i was going to fit clip on handlebars just below the top yoke & was wondering if anyone has already done this & is it a comfortable riding position.

Hiya......I am that man ;D
Now..the blue bike (#4 srx) you see has a very nice pair of Thomaselli clipons fitted (I picked them up on Ebay, in germany)
#1 srx (mine) has a pair of clipons that are a bit clunky, but have a vernier adjustment, which makes it easy to set them up to suit your riding position.
#2 srx, a 400 that I sold to Andy230's mate, had clipons which were just the standard ones, modified...... You do this by removing the lugs that screw into the top yoke....smooth them off and polish them......then slide them onto the forks between the top and bottom yoke......they 'just' clear the headlamp support bracket....and you are limited to position by the brake master cylinder on the right........I also use these on my srx track bike.....the position seems just about right ...for me anyway.
#3 srx, a 600 sold to a plumber mate of mine.....also has modified standard clipons...and he's happy with them....if you want i'll get a pic or 2...
you really need rearsets to go with clipons......
then you'll really find out how good your back is ;D
Actually, I find, that at 60 mph + your weight on your arms is balanced by wind pressure on your chest.....but bu55er! 15 mins round town sorts out the men from the others

Missed the carbs bit.......
how much money you got????
nice pair of flat side 36mm carbs on fabricated manifolds do the business but you'll flog your house to keep up the payments.
I use twin 36mm amals on my track bike.....john the plumber uses twin carbs off a bmw (rotax) on fabricated manifolds (cost him 200 quid)....i have twin 34mm dellorto's on my road bike....which is well over 620cc now, with 10.5-1 hight comp piston.... and that goes well enough......but....
the blue bike (#4) is now running at 640cc with high comp piston.... and the standard carbs 'dynojetted' and full flow filter......and it works really well, probably as well as my road bike
so.......'bang per buck' the dynojet kit and air filter (at approx 70 quid) is the route I'd take
Oh...and on my other track bike i run a pair of 34mm amals (picked up at the bmf for 30 quid!) rejetted.......and thats a stonking motor
-
cheers for the info lads , it,ll be a big help
-
steveL you say a standard dynojet kit on origional carbs is it a stage 1 kit or a stage 2 mine is only bored out to 620cc
and a full flow air filter does that fit into origonal air box or do you mean
K & N type cone filters that fit straight onto carbs
i noticed the carbs are a funny set up 1 is a proper carb what does the other one do sorry for sounding daft but these bikes are new to me ??? ???
-
The standard carbs are a bluddy nightmare.....but they do work well when clean and set up correctly...I'm not sure what 'stage' the dynojet kit is....but there is only one available, so choice isn't an option. And the upgrade will work fine on your motor.
The carb is indeed a 2 stage affair, the l/h part is sort of butterfly affair, and is in use all the time, the r/h part is vacuum operated, and comes into use once the throttle is opened sufficiently (with the engine running) it is supposed to make the bike more economical and tractable....but I don't really notice a great deal of difference in economy between the standard carb and a pair of twin dellortos...maybe it's because I keep my bikes nailed most of the time ;D
the airfilter can either be a pair of k&n's clipped directly onto the carbs, or k&n also do a freeflow replacement filter for the standard item....the second option is cheaper and A LOT easier to fit.

If you are looking for rearsets i have just made some new ones that puts the footpeg aprox 100mm back.

I have found a photo in the projects section.The rearsets are a copy of the ones on Andy,s race bike that i made for him after that spill last year when he put a hole in his foot.See:-Photographs:=Projects:=13th row down,4th photo from the left.

alan how much would you want for rearsets do they bolt straight on or do you have to make any mods
cheers nipper
-
If you have a CAD file that would be fine, i have access to Autocad....b ut it would need to be a compatable version I think (although autocad is backward compatable i think)
-
Hi Nipper
You can have a pair for £25.00 inc postage as long as you are in the UK.The only mod you might have to do is open the holes out.At the moment all three holes are 10mm diameter.

Alan
-
Alan, I'd be interested in a pair as well if its easy to knock out a few sets at the same time.

Your logged in status should be displayed on the right handside of the title bar (the one with Thumperclub logo). This should say something to the effect of "You are Logged in as Srx6" or "You are not logged in xx.xx.xx.xx" where xx.xx.xx.xx is your IP Address

i,ve fitted my rearsets just waiting for pegs yo fit on they are the dogs bollocks only needed a little bit of grinding to get by frame welding 10 minute job to fit
you can see them in project pictures TOTAL REBUILD
-
Looked at the photos and i must say they do look good.If your pegs are like mine that i fitted to my Goose they will have two square dogs on them to stop them from twisting around.An easy way to fit them is to drill the rearsets with the dia that is the size of the width of the dog then with a file round the dogs of to fit.Does that make any sense to you?
Regards
Alan
-
yes alan it makes sense my pegs are on order and i.ll see how they fit. did you receive cheque i sent
regards nipper
-

Hi I like the idea of modifying the standard clip ons. appeals to my sense of not spending any money. Are there any steering issues for example do you have to position them sticking out a lot to avoid touching the tank on full lock or can you have them at the same angle as when they're attached to the top yoke. Sorry difficult to explain the question without pics.
cheers
Julian.

check the photo of my bike on the first page of this thread.....thats about what they will look like
