Power Problem On 92 Fantic K-roo

[nimky]

hello,

I've got a 92 Fantic K-Roo 212cc - It's got a wierd power delivery problem:

I can go up slowly through the revvs on a flat surface, but if I suddenly accellerate, or put the bike under more load (e.g. go up a hill) it just drowns out.

I've tried taking the exhaust (tailpipe) off and no difference - so not a tailpipe problem

I've had the carb cleaned out

I've changed plugs

Anymore bright ideas? I'm looking to get the bike fixed up and sell it (Dundee, UK if anyone interested!)

Thanks

tried setting up the carb? does it idle and rev fine??

I had a hint to do my gasser.

Get it running and warm,

turn the tickover right down, (but so it still ticks over,

then turn the mixture screw right in, (to lean the mixture)

and then turn it out half a turn at a time,

after each half turn, test throttle response quickly,

if its slow to respond then take it out another turn,

i know on gassers you should have to take it out more than 3 turns,

Not too sure about fantics tho, hope that helps??

low coil on stator plate you can get replacements from bill pye,you can check the measurenent with a volt meter should read approx 475 ohm, if i remember right dissconect green wire from coil and measure between this and earth this cured my fantic 303 OR on my 307 it was the pick up on the stator
