Recommended Posts

i just put myb engine together..set up is..

4mm crank

cool head 22mm domes

v force 3s

timming plate at plus 4deg

reed spacer blocks

34mm mikuni flat slide carbs..btw this engine is in a road bike

prob is that at about 4thou rpm the bike seems to pulsate.. almost turbulant like, its quite odd i never experienced it b4 if i rev straight past it its fine but 4tho is about crusing speed so its a real pain.. it doesnt miss fire or seem to be starving it just feels like it things i have tried

removed the spacer blocks no different

raised the clip which richened it up..it was better but still not all that good at the bike was too rich and fluffy...could it be the timming i think i will try stock timming tomorrow..anyhelp at all would br great thanks
