[quote=machinehead]A few ideas from my own RR-W experiences - I ran mine for 6 yrs and 42,000 miles and never went to a garage with it, so have had a bit of experience!
Assuming its got carbs, which I guess it would, I'd
* water in fuel
* some other much partly blocking a jet int he carbs
* kinked fuel pipe
* dodgy vacuum tap in the tank
* and lastly, real odd one that had me fooled... if you've had the tank and/or air box off beware of this. On the RH side there is a breather from the carbs that vents the float bowls and its easy to kink this putting everything back together, of course when you take everything off to find the problem it unkinks so you never see it! The kink creates a ploblem that stop the bike revving out, but only noticable under load when riding, seems to rev ok in teh workshop.
Best of luck!
hi thanks for that but all those are fine you can ride it hard and its ok.
just seems to be when you hold the throttle in any possition eg 1/3 1/2
it also wont respond very well if you snap it open .what does the throttle sensor do ?i unpluged it and it made no difference at all?????????
