DR650 off to Valhalla??
« on: November 11, 2012, 09:15:54 PM »
Hello all,

Not been posting for a while, but still lurking  :D  No singles news really!

The 1991 DR650 has been ace and utterly dependable for my boy's first year of life, MOT time in a month.  Lets give it a clean up, and a once over.

 :o  Wait!  Whats that "clak clak clak"  Must be the tappets, when did you last check em?  Must be, oooh, 2 years?  3??   ::)

Anyway, tappet clearances were predictably huge.  But still she "clak clak clak's"   :-\

Oh-oh.  Sparkly oil...   :'(

I dropped by Burwins, great guys, MOT men, MZ racers, for an opinion. 

They reckon a bearing at either end of the rod is letting go, thus the "clak" is the piston clipping the exhaust valve(s). 

So they said "don't waste yer cash on an MOT!  And use the 30 quid for the skorp MOT", tho did also say that if its still alive in  month they'll gladly test it (and it looked like it would pass)!  If I get the winter out of it before it expires, I'd be delighted.  (It does 15 miles per day, central london.)  And then put the Skorp on the road come Spring.

So, while it is still ridable, running, taxed (till July) and MOT'd does anyone want it? 

To be honest, I cant justify rebuilding the motor.  The cases will need splitting, then every bearing.  And the chains.  And surely a piston, rings, bore, valves, yada yada.  Gaskets are even dear!

And its lumpy as f'ck and not very well carburetted anyway (US import, modified to remove evaporation control rubbish.  Carb tired?  Or just not set up very well?).  But utterly reliable.  Always starts.  Always.  Stops as well as DR's do.

In the 5 or 6 years I've had it:

New header pipe 3 years ago, new s/s micron can when I got it
Rebuilt forks 18 months ago   Genuine $uzuki $eals
New C&S 1 year ago
New tyres 1 y ago
New shock 2 years ago  (Hagon, adjustable, not cheap, covered in Waxoyl)
Heated grips (likely dodge by now?)
New clutch (metal and friction plates) 2.5 years ago.  Genuine $$$$uzuki
EBC pads & rebuilt brakes about 18 months ago.  More expensive $uzuki piston seals.  I seem to remember I got stainless pistons too...  Stainless front line.
New rear spindle and wheel bearings and hub bearings 18 months ago
There must be more.  I have spent too much money on it, but this one is probably "goodbye old frend".

Immediately prior to my purchase, it had a new front disk. 

Tho admittedly, I do paint over a crack in the frame every year, on the drive side, just near the side stand mount.  The MOT man does a very good Albert Speer impression, and claims to be ignorant of anything amiss under his jurisdiction.

So does anyone have a DR650 they need a parts bike for?  The plastic is all good, the tank is good, but has nicks in the paint, and the decals have worn thru.  But there is no filler, no dents, and I think no rust.. Seat is good apart from one nick.

Kickstart only. So the battery is predictably gubbed!!

ALternatively, I'd love a 650 (or even DR600) kickstart motor, which is known good.  But I think that is most unlikely!! :'(  Anyone??

So in the absence of anyone taking it away, I'll break it on ebay as there is good stuff on it.  And I'll keep the Hagon shock.  But 1 year old son = not a lot of time to break a bike for which parts are not in very high demand, so I am not that keen...

I'm not looking for a lot of cash, is anyone interested?  If really pushed, I could even deliver within M25, but cannot guarentee that I'll get there!!

There are some piccies on the site, and plenty of threads about shocks, brakes, etc.  Ideas, laughter, commiseration on this thread please!  I hope this finds all well and happy.  Its been a good year for me, with the kid and all that.  Time's abit tight tho for tinkering with bikes and silly plastic cars.  So I haven't been.  I think I'll be pressing the Skorp back into service quite soon.

before you do anything take the rocker cover off. dr650 motors have an achilles heel, loud and sudden tapping from the head is almost always the exhaust cam follower that has worn through its hardening. the cams can go fecked too. try ringing the breakers, they will have everything but the cam and followers. im told that phil joy of joy cams can build them up with stellite weld and re face them both the cam and the followers. i suspect that your garage was perhaps lifting your leg by telling you that. check the cam first. 
and in future you need to be anal about the valve clearances and oil changes.

Aye Andy,

Pleased to read of progress all round and not surprised to read that the 'loon' is occupying time over the bike and the 4 wheel plastic pig.

As for john's comment "and in future you need to be anal about the valve clearances and oil changes." !! ??? I believe you are of the school of 'Thrash'em 'til they drop!', many good scratchers are. However, he has a point!  ;) Just make sure you don't have an "Armaggedon!" moment like this one! (Link below ;D This requires parental authorisation!!!! 12yrs  ::) )

"Armageddon!"

Good health, Bill.

What is of perennial concern on this site, and Bill this is a classic example, is what one is searching on the internet to find this sort of material. :o

Andy, I am sorry to hear about the DR, hope you get it sorted out and best of luck with the Skorpion. A shortage of time and a preponderance of failed main seals will see me using my Skorpion this winter in place of the 2Ts  :-\

Very interesting John, thank you very much for that.  I didn't know that, there is not a lot of interweb info about the foibles of the DR, that there is for (for example) the skorp, or the SRX.  Although maybe its just harder to find given the very long production run of the DR and its many variants.  Is it still going???   

So maybe its not "its time" just yet...

(Time to MOT the Skorp tho!)

I will take your advice and remove the rocker box.  Will let you know what I see.  A "quick keek" inside with the inspection covers off did show a rather scuffed lobe on the cam, but I was not really too surprised at that...

To be honest, I wasn't that sure about the piston clipping the valve- I wouldn't have thought it would run (and it does, as well as it ever did).  Just noisy.

I will have a look around for servicable old ones, but will also phone Phil Joy.  Cost may be prohibitive tho....    The bike is worth spending a few hundred quid on it, but I have to be realistic.

I am thinking I should get both lobes and both followers done?? 

Will let you know what I find out.

Thanks all, nice to hear from you guys!

Good luck Andy, I hope it's fixable.

havin the cam and followers both refaced will be the best bet, much cheaper than buying new. im told its only the 650dr that is affected like this. if there is any wear at all on the followers or ny scoring on the cam, then take them out and get them done. they'll be better than new then.
i was at my mates house on sat, he has a dr650 with only 10 thousand miles on it, and after running low on oil on a run out, no running out, just running low, he got the clattery top end, and thats what it was. he showed me the followers, theyre pretty worn, thas how i found out about phil joy. if you bell him he will probably say he has a cam on its way from scotland for refacing.

Hello guys

Thanks for the advice, and the hellos! 

I will let you know how it pans out.  I will probably get it done, but get the skorp back on the go in the mean time. 

As an aside,  here is me trying to show the boy the joy of the feeling that motorcycling gives you!

(look at that happy face!)  -->

Aye Andy,

Good to see the wee fella in good form. Hope all goes well with the rebuild.

Steffan Apologies if 'Armageddon' caused a disturbance. I received the link from a member of the keepering fraternity up here!  ::) Long hours dancing with midges, clegs and rolling in peat bogs, covered in ice and snow, a long way from anywhere, can have an adverse effect on the humour. ???  The mind pictures of the gerbil being expelled at speed, are of 'Tom & Jerry' quality! ;D

Good health to you all, Bill.

Yeah, I know what you mean!!  Not my gaff, I was just showing off to mates about what an adventurous chap my son was.

I did once scud his cranium off a particularly low ceiling, but was lifting him out his pram, not launching him skywards.  Genuine accident!

They love all that being hurtled around, dont that?  Its nuts!  I am sure the social workers would be less impressed!

Sadly no footage exists of the delight at him being put in a shopping bag and being hurled around and round at a vast rate of knots.  He loved that.  My wife asked me to stop after she noticed the handles coming off the bag!!!    ;D 

First day of nursery today.  Its probably for the best...!

Will post photos of the cam and followers when I get it apart.  (The DR, not the baby)

Are you sure about that?  ;)

Pass the Whitworth, the ES2 needs the tappets 'doing' as well!

Slainte, Bill.
