Title: XBR replacement tank
Post by: mthee on January 15, 2019, 12:35:53 PM
I wanted to put a CB350 tank on my XBR and got one cheap off eBay because one of the balance pipes had come away. Perfect, as they need to be removed and rotated to clear the frame rails. The tank came without a latch for the cap, so I bought a CB200 tank for the latch and to practice shaping the underside with. All went well and in fact, I really prefer the super-slim CB200 tank.
It needs a pet******* bung welding/brazing in, but I can only find 22mm Harley ones, rather than the 16 X 1.5mm used by Honda.

Which is best, design-wise, the male one with the extra step or the female without?

Good evening Matt, have you thought about a flush fitting fuel cap, that's what I've popped into the "tracker" tank. Looks the bizz. I'll send you some photos later. If you type in "weld in petrol cap" on fleabay I think it's the first pic that comes up .... cheers, Michael

Got your pics for posting. Nice. The fact that you're a plumber fitting a flush fuel filler made me chuckle! Saw your welds 8) Wish I had your skills! I'm happy with the nice Monza(?) style cap that came with the CB200 tank, ta.

Evening Matt I use an Electric tig welder....and yes , the FLUSH fitting filler thing went right over my head.🤣🤣  We did do a fair bit of oxy/acetylene brazing during my apprenticeship days, I absolutely loved doing it and got very high marks in my exams for my work but haven't really done any since. Don't know why really, I need to buy a small oxy kit me thinks. Try and get my hand back in to it. Big bro (propeller) used to have a CB200 waaay back in the day, I never really liked the fake leather squares down the tank, although I think the shape is lovely. Best of luck with whichever route you decide to take. I look forward to seeing the result👍👍.... cheers, Michael

Some pics of my somewhat neanderthal reshaping of the undersides using a 40oz ballpein.

XBR tank added for comparison.

A smear of that there body filler and a licko paint and nobody will be non the wiser Matt 👍
Title: Re: XBR replacement tank
Post by: mthee on January 16, 2019, 03:19:55 PM
A couple of other angles. My fave, the CB200 has got rust aplenty, so removing that will be a first for me. Electrolysis followed by oxalic acid and 2T oil. Welding in a new bung first and not having a local Michael, I found there is a local guy who advertises himself as Bob the Welder!
Let's hope we get another roasting spring - great for painting.

Post by: Moto63 on January 16, 2019, 05:55:08 PM
Yes I too prefer the look of the CB200 tank Matt. Just a bit of advice if I may. Make sure the bloke who is going to weld your new filler in is happy doing TIG welding and don't let him do it with a MIG welder. To much heat maaaan, will most likely badly distort the tank. Also if the tank is bad with rust and if he's a decent TIG welder, I'd seriously consider cutting the bottom of the tank out, that way you can get in with some course wet n dry and sand it down inside. Then just get him to weld the underside back on. Probably only cost you an extra £20 to £30. .... keep me posted and best o luck 👍
Cheers, Michael

Thanks for the inside info. He was recommended by the local sheet metalworks who were too chocca for the next 6 months. He's retired, so hopefully years of experience, but although he offered a derust service (it'll have to be DIY for me, as money's tighter than a Brexit deadline!) he didn't offer your proposal.
Title: Re: XBR replacement tank
Post by: Moto63 on January 16, 2019, 06:33:39 PM
"Tighter than a brexit deadline" I like that one 🤣🤣...... just thought that if he's happy to do actual welding bit you could cut the underside out yourself and rub it down then pass it on to him to do the "technical " bit.... the welding 😁😁👍
Title: Re: XBR replacement tank
Post by: mthee on January 16, 2019, 06:37:56 PM
Me cut the bottom out?! Ooh, err, what tool for that then? :-\
Title: Re: XBR replacement tank
Post by: Moto63 on January 16, 2019, 06:51:16 PM
Just use a small grinder with a thin metal cutting disc in it, you may possibly need to revert to a dremel up inside the tunnel at the front of the tank looking at the photo you posted. Please make sure he's happy welding it all back together before you do any cutting 😁😁👍..... personally that's the route I'd take if there's a lot of rust inside the tank. Peace of mind that way and you're beating the underside to fit anyway. ....
Title: Re: XBR replacement tank
Post by: mthee on January 16, 2019, 07:04:04 PM
Testicular fortitude (or lack of) notwithstanding, I'll probably go cheap and run an inline filter after electrolysis and acid. If I like the tank on the bike and decide it's a keeper, I'll probably keep an eye out for a cleaner one. Thanks for the tip though and may I just say, damn, you really produced some good looking welds on your flush filler. Rispeck, innit!!!  ;D

Interesting thread this - I'd often thought about what alternative tanks could be made to fit the xbr. The company Caferacerseats supplies a range of universal fit tanks (and many other parts) some of which might work with the xbr - reasonably priced too as they include fuel tap and cap. Would have been interesting to see a side view of them sitting on something like a CB500 to get an ideal of scale and how they look.

And at those attractive prices, one is even painted for you!

Here are some measurements I took from my XBR tank for reference;

Max length 640
Centre (front mounting) cups to centre rear mount hole 527
Centre cups to centre pet******* 230
Centre cups to rear of toptube where frame rails attach (and width goes from 65 to 75) 200
Centre cups to start of max width of 160 (outside seat rails) 360
Width of tunnel between cups 110
Diameter of top tube 65mm (CB200 cups had to be trimmed to gain clearance)
Height from cup centres to top of toptube 75
Max width 310

Worth reposting here what was included incidentally to my posted appeal for a CB250RS brake plate;

Joolz has a CX500 tank fitted and says it's an easy mod, needing only longer rubber mounts up front, or washers under the originals and a trim of the rear mounting tab. However, you then have to match the seat to the new tank face and you'll have lost the side panel mount that the XBR tank provides.

Here's a CB400N tank being used (same as 250N) but the builder doesn't describe how he did it, other than to say it needed a "soft" frame modification, which might mean no welding.
http://www.bikebound.com/2018/08/07/honda-xbr500-cafe-racer/

GN250 tank here;
http://rhcc.pl/ajs-trial-replica/

I nearly got my hands on a CB650 tank which looked like it might have nearly gone straight on.  The CB750/900 tank is longer.
The SR500 tank also looked good, apart from tunnel widening and the gap left where the oil filler cap on the SR frame top tube is located by the headstock.

The GS400/425 was also good looking on measurements supplied by eBay sellers, having a 160mm tunnel to the rear of the tank which will clear the frame rails, but the pet******* might need repositioning and seat and side panel considerations remain. Also front mounting posts on the XBR will need cutting right down and the cups on the GS tank trimming to allow the tank to clear the XBR top tube.

Thanks for that - plenty of information. I've seen one fitted with a Honda 400/4 tank (I think) and it looked well. Not sure what modifications were needed though and they probably aren't cheap now with the current demand for 400/4 parts.

Well it does say he may be open to offers and postage varies. I've owned 3 400/4s over the years (2 blue and one in red). Sold the last one about 5 years ago. Got it cheap as it had been standing and it turned out the rings had stuck in the bore over time. Cost an arm and a leg to have the 4 pots rebored with piston kits etc and gaskets to add insult to injury. Then the carbs got all messed up with ethanol so they needed stripping and rubbers replaced,then it need new coils and the list went on and on. Did eventually get it running well but then it needed a cosmetic resto but i'd had enough by then!

Very useful seeing how some of these tanks look. Interesting to hear about the Cadwell tank too Joolz. Worth keeping an eye out for a used one. I think they hold around 11 litres. Link to the AJS Cadwell parts prices :-

Received the pet******* from eBay lathe engineer, made up for £18   :) Took it to the local shop, where matey TIG welded it on no probs, but really struggled with filling the old pet******* holes because he said the tank was Swiss cheese. He built up a big weld using his MIG and said although I'd need to use a liner, to test it first and return it if it leaked so he could go over it again. Got it home and it leaked from the sides of the weld, maybe at it's base  :'(
Does this mean the tank metal is too porous/rusty? Lost cause? Michael?

Title: Re: XBR replacement tank
Post by: Moto63 on February 01, 2019, 10:51:53 PM
Evening Matt. Yes quite possibly. The tank that Tim (timbo) very kindly let me have for just the postage costs to practice on turned out to be like that. Wafer thin and an absolute nightmare to tig weld anything to it. Like I say Tim had told me that it was pretty much knackered but was worse than I'd expected. So in answer to your question, yes if the metal is wafer thin then yes most likely become porous. 😢😢. Best o luck with it. Cheers, Michael

Not to sure to be honest Matt, never used it mate. Got to be worth a go tho Shirley. Plus possibly a thin smear externally of something like araldite. Not to sure how araldite copes with the modern fuels? (Anybody out there have some info on this??). Still gotta be worth a shot trying it out, then pop some fuel in it for a few days before it goes off for spraying. Assuming it works obviously 😁😁🤘Best o luck and keep me posted .... cheers, Michael

With the CB200 tank now firmly mounted (no, not like that, vicar! I like it a lot, but not that much!) I've found that the resulting triangle is too big to fill ( :o)  What I mean is, the smaller tank makes any side panel needed to cover the airbox and battery triangle appear too big. So, the airbox might have to go, leaving me with a K&N question for Moto63. I understand you ran one successfully on an original XBR carb? Was it this one and is there any rejetting/ needle lifting required?

Post by: Moto63 on February 28, 2019, 07:42:15 AM
Morning Matt... no I didn't run my cafe racer on the original carb, I bought a mikuni standard slide type (not a CV) then popped a conical K&N filter on that. I can/will dig out the relative paperwork to refresh my memory on the actual model of carb and let you know. I remember it wasn't as expensive as I thought it might be. I'm not saying it was chirpy, chirpy CHEAP, CHEAP (song in there somewhere) but defo not bank braking figures.... I am a Yorkshire man after all 😁😁👍.... I think you'll struggle to run it properly with the standard carb with no air box. Any pics yet of bike with CB tank fitted, looking forward to seeing them 👍.. cheers, Michael

Post by: Rossco500 on February 28, 2019, 08:02:22 PM
Hi Matt - not sure if I am interpreting what you are saying correctly but looking at the photograph with the xbr side panel in place, you might find it looks ok if / when the tank and panels are painted in the same colour. If you can open that photo using the one of the graphics packages on your computer (Paint?) you might be able to get an idea how it would look and possibly add a seat. Also, you might be able to reduce the look of the "triangle" on the side panel by increasing the width of the angled black section (which Honda has effectively already done). Not sure if any of this makes sense! Lol

As others have suggested it can be quite tricky setting up a carb without the airbox

Regards

Tony 
Title: Re: XBR replacement tank
Post by: mthee on February 28, 2019, 10:24:13 PM
Thanks, Tony. Side panels are sold, so it looks like I'll be trawling Google for inspiration. I want something different anyway and it will come. Metal covers for the airbox housing and an oval plate for the battery area, or vice versa, maybe. Having bought a jet kit for a CB900 I ran with Ram Air foam pod filters years ago, I had thought CV's were tunable with just patience and a handful of jets  ::) With the XBR needing only one carb sorting and the success story in the link above, I was sorely tempted!
Title: Re: XBR replacement tank
Post by: Moto63 on March 01, 2019, 07:52:06 PM
Looking good Matt, all that bike needs now (apart from the tank painting 🤣👍) is those side panels ditching and a lovely CARB throwing on there for everyone to look on at in absolute envy 😉🤘. That's when you'll get all n sundry asking you how it runs with the "original " carb with just a pod filter bolted on. At which point you can stroke your chin and suck thro your teeth and say..."yeah runs just fine"  😁👍

Any advice on cone filter manufacturer? I'm looking at K&N and DNA.

I'll admit to getting sucked in (sorry) by the DNA blurb.

I'm guessing my Motad 2:1 isn't very free-flowing, so does this mean the shorter length (lower surface area) filter will be the best match?

Good stuff Matt. Like I say mate, my bike ran totally fine with it as it was, so personally I'd just give it a good external clean with said toothbrush and solvol. Bolt it on and try it first. Hopefully won't need to strip it down. As someone on here has as their strap line "if it ain't broke, don't fix it" wise words I'd say.... best of luck with it. Keep us posted🤞👍.. cheers, Michael

I thought it was "if it ain't broke, fix it 'till it is". Which is definitely more amusing.

Good luck with the carb matt. It'll be fine.

I could use that £50 to fix a short bicycle pump onto the carb body, then I could boast of a Mikuni TM40(?) Flat slide pumper!  8)
Because there's a handy drain plug which allows the main jet to be changed on the bike without dropping the bowl, I had a peek and it's a 230.
Does it need a specific throttle cable? I didn't get that far, coz the missus caught me out and thinks I've paid for it when we're supposed to be saving for Butlins!  ::)

Title: Re: XBR replacement tank
Post by: mthee on March 16, 2019, 10:45:24 AM
Well, I must confess, I lost the choke plunger the day before yesterday. It had got stuck in it's bore, I'd applied heat and pulled on the cable, tapped the body - no movement. Repeat - nothing. Repeat and out it flew - hurray! Except Matt no brains was standing outside the garage on the pea shingle, so focussed on dislodging the plunger, he hadn't considered what might happen when it emerged. The plunger shot off the end of the cable and lies somewhere on the drive, but small brass bits are hard to spot on pea shingle and non-magnetic. Anyway, if it's reachable, I'll probably put one of these in it's place;

https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F192468273290

Plus, I might need one of these;

https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F201506513499

Or there's one at 90 degs.

Should happen tomorrow. Old carb off, Mikuni in place and check for clearance. A quick look made me think I might have to relocate the reg/rect, but it really is all gravy and I'm having the time of my life. I even managed decent welds on the tank mount with my flux core! With a tag line like, "if you slag,  you drag" who could resist!!!!

Title: Re: XBR replacement tank
Post by: mthee on March 16, 2019, 02:43:30 PM
Got some unexpected time and here's the verdict - reg/rect has to move, but leaves behind a tab and grommet almost directly above where the cable goes in, so it might act as a guide for the outer without the need for a dedicated elbow  ;D Cable runs nicely under the CB tank, although I'll need the right length and nipple.

Placing hand on latest copy of MCN....."In the presence of Moto63 and members of Thumper Club, I hereby solemnly swear to apply Autosol by toothbrush to Mikuni TM 41 Pro-Series Flatslide Carburettor, so help me, Joey Dunlop" - that do ya?  ;D Got the choke and top adjuster bits coming, so just need the right cable length and to see whether I can avoid having to make one up or not - it'll come down to price, probably.
Anyway, since I'm keeping the battery, I got some 1.5mm steel sheet and had a go at folding up a box for it  ::) Got away with the folding, but welding the sides up was a different matter and reminded me of the saying I read a lot on welding sites, "Grinder and paint make me the welder I ain't"!  :'(

If I'd have known I would have sent an old toothbrush down with the carb, got quite a stash in the old workshop 😁😁. If you've not got an ac/dc tig welder Matt you'll probably not weld ya folded ally. You tried "no nails" (joke, joke.... I WAS joking)

I wish! Mine goes down to 30A, so I had a go at stitch welding to try to make the best of it, but, let's just say, I'm glad the welds will be hidden.

Spotted this video of an XR600 tracker and am thinking about using the same TEC silencer, as it would mean I can shorten the footrest hangers;

Can I get opinions on noise levels and whether this unstamped silencer is likely to pass an MoT? The bike can be heard towards the end of the video.

Evening Matt. Personally I think it all depends on the mot tester who you deal with. The guy I use is pretty "olds cool" so when I used to take the cafe racer in (which was much louder than the dommi in the video) he used to give me an advisory for the exhaust. If they're the ones you're fancying I'd go for them. Then again that's easy for me to say as I personally would be pretty confident that my tester would pass it come MOT time 😉🤘
Name withheld to protect the innocent 😉

Maybe I'll put one on and delay trimming the footrest hanger until after the MoT, just in case the Motad needs to go back on.
Best to just put it on for the MoT and hope it passes, or pop in for a chat first?

Matt... live life on the edge, in the danger zone!!...... just buy em, bolt em, wake the neighbours on an Sunday morning with them and then go ride the hell out of it. 🤘🤘
Should it fail the mot because of the cans you can always pop the motad back on like you say then hey ho instant pass 👍

Ha, ha!  ;D Or should I say, "Yee Ha!"? It's worth the gamble to shorten them thar pesky hangers...
Title: Re: XBR replacement tank
Post by: Moto63 on April 11, 2019, 07:20:39 AM
Woh... there cowboy, slow down. Them thar pesky hangers are worth a bob or two. Pop em on fleabay get cashed up then whittle ya self some new ones outta some 10mm ally plate. Do your own design to suit the new fancy shmancy end cans that will by that time be residing on your steed. 🐴😉... if you cast your eyes back to my tracker pics I think there's a couple of pics with the hangers I whittled up outta 10mm plate....
or you could just simply get out the big hacksaw and launch half the original hangers 😁👍🤘
Either way keep us posted...really looking forward to seeing the completed bike, cheers, Michael

 ;D Time, tool and skill set-wise, it'll be Harry Hacksaw. Besides, I've seen a couple of pics where the cut down hangers look really good. At the rate I'm going, it'll be June before I'll be finished and that's having even shelved plans for the spoked wheels, forks, speedo and light!  ::)

Evening Matt... yes mate I went that route on my cafe racer. I cut off the rear footrest hanger on the exhaust side then cut and filed the other side down to a single footrest hanger... looked good when I'd finished

Looks like the same silencer I use, I found it very loud even with the removable baffle fitted, I solved the problem with a longer baffle fitted in place of the removable one that came with it

I was so busy listening out for the supercharger whine on your video, that I completely missed the replacement of the peashooter with this silencer ::) Looks good!

Great tip, thanks for sharing. I was planning to add in some packing material, but might combine the longer baffle as well. Did you use packing on yours, Joolz?
Title: Re: XBR replacement tank
Post by: JOOLZ on April 12, 2019, 05:38:38 PM
Thanks, the old BSA Goldstar exhaust sounded good but was too restrictive. These slotted baffles work much better than the ones with the holes (this might not be the right diameter but same type), no I didnt bother with packing I found the slotted baffles gave a nice tone and not too noisy.   https://www.ebay.co.uk/itm/EXHAUST-SILENCER-BAFFLE-35mm-CHROME-4-STROKE-DB-KILLER-TRACK-DAY-QUIETEN/281140937828?hash=item41754e4464:g:2eEAAMXQ3kRQ8cJy

Electrical fault sorted, bike went for MoT. The very nice bloke noticed the missing nut on the torque arm and put one on, before passing it - proper decent service! On the way home, my novice efforts to solder a throttle cable end on without purchasing a solder pot (I used a radiator end cap and butane torch) came back to haunt me, as the cable pulled through the end  ::) I had to walk alongside the bike in first gear for 3 miles in the rush hour - the walk of shame - that'll teach me  :-[
Next day, solderless end went on as the shops were too busy and off I went, only to discover the cheap Chinese petcock was intermittently starving  the bike  >:( >:(
On the sunny side, the tank looks good and the POR 15 kit has sealed it well thus far. More work is needed on the seat.

Dang! You've obviously spotted that I didn't get near it with the solvol and toothbrush! Many thanks to you, it looks the biz with the oval DNA filter and after 6 months off the road (after several kicks, ignition off, to restore compression) she fired first kick  ;D ;D ;D
Beers at the show? IOU kegs, my friend!

Judging by the first photo Matt.....it looks terminal, I'd have given up and broken down in fits of tears at that point....then gone and drunk lots n lots of ALE 😉🍺🍺🍺🍺🍺..
Judging by the second photo all looks well 👍👍

Thought I'd chuck out a pic of the XBR to get opinions on the steel discs I'm using to cover the battery box. I've mocked one side using a paper cover, complete with penned lines to follow the tank design.
What do you think? Other idea is white discs with black numbers, like a small number board.

Thanks, Joolz.

I'm thinking of locating 2 warning LEDs in the top of these hollow bolts to go in my bar risers, but the seller doesn't have any torque specs. They're M8 stainless with a 4.2mm hole. I probably need 30-40lbs of torque.

I'm currently looking to use a headlight which incorporates a speedo and came across this one on eBay. It being Italian, I doubt my standard (2.5mm?) square end cable will go in. The vendor says he doesn't know what bike it's from, but I thought Bill might ID it?

https://www.ebay.co.uk/itm/143614732305

Bike's got side panels 😁
Title: Re: XBR replacement tank
Post by: Moto63 on May 27, 2020, 06:05:42 PM
Matt, Daytona do a black headlight with a speedo built in. I would imagine it will be a universal cable mount. Don’t think from memory that they are silly money and it’d be a brand spanker... ooo eerr, more tea vicar
Title: Re: XBR replacement tank
Post by: themoudie on May 27, 2020, 11:41:39 PM
Aye mthee, appears to be typical 1960's lightweight Italian headlamp and speedo. Cannot be specific from which model of machine it might come. Similar to Joe Lucas and Smiths. Aprilia headlight shell and Veglia speedo.

My Dukes all have Smiths speedo that are the universal 2.5mm square drive (need to measure to be sure!).

Headlight shell looks OK, speedo may work, but the needle could waver about like a rag in a Force 10! Mini speedo heads are of a similar size, but again the quality is VERY variable and reflected in the price.

I doubt if this is what you wanted to read, but will measure up later today and post on this thread.

Regards, Bill
Title: Re: XBR replacement tank
Post by: mthee on May 28, 2020, 10:31:05 AM
Thanks, Michael, but too new and needs one of their digital Speedos so around £250 all told??

Cheers for the good info, Bill. You're right, I'll pass, as I like a reasonably accurate speedo.

At the moment, it's between these 2;

A 7" that someone had in storage for their Norton;

A wipac which uses a 5 1/2" reflector (so 6" overall?)

Any advice, comments gratefully received
Title: Re: XBR replacement tank
Post by: themoudie on May 28, 2020, 10:46:06 PM
Sincere apologies mthee, still not managed to measure up cable dimensions etc. eBay going well and the garden needed sorting! Will try tomorrow after the Post Office run.

Bill
Title: Re: XBR replacement tank
Post by: mthee on May 29, 2020, 09:12:24 AM
Thanks, Bill. I would be interested for future reference. Even if the cable section is the same, I doubt the speedo drive ratio will match the Japanese standard 2240rpm=60mph?
Title: Re: XBR replacement tank
Post by: themoudie on May 29, 2020, 09:04:21 PM
Aye mthee,

Square drive in Smiths speedo equivalent speedo is 2.5mm x 2.5mm.

The square end on the cable is 2.3mm x 2.3mm.

There is no drive ratio printed on the face of the instrument. I would need to dig out the helical, phosphor bronze drive gears to get some idea. However, I only have Grimeca 230mm Dual-SLS front drum brakes and the speedo drive for the older Ducati hubs and other Italian manufacturers from the period of the Aprilia headlamp shell and Veglia speedo may be different ratios.

My regards, Bill
