Does it start easy enough ,what does it do when you open the throttle ,is it when it's moving or at a standstill

kicks up first time but will not rev at all wont raise the engine speed at all and if you open the throttle up it just stalls , had the plugs out and they get wet so suspect electrical but which one ?? cdi,rotor or coil

and back to the original question, float height wrong or sticking partially closed? Some other fuel starvation? Blocked main jets?

ive tried all the carb thing to no joy mate also sometimes the spark looks weak and others a bit better but it never really looks blinding , ive bought a load of bits today and i got some 1ua carbs with the extra pipe from the float bowl are these any better or not really any difference ?? think ive got another rotor and flywheel sorted so ill just keep trying new bits till the bloody thing is sorted !!! still need a cdi tho lol . oh and i had to get a new battery and an optimate for the r1 last year and its been faultless since bless it

Had a similar thing happen my F2 when one of the main jets fell out 'cos some goon didn't tighten it up -- wasn't me, honest ;D So... could it be something silly like totaly wrong needles in the carbs?

Hi, if it was the cdi then the bike would'nt even run, i would check the ignition pick ups that's the thing which makes the bike rev.
