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 N
