i tried a search relating to my issues,didnt find what i was after.
new 66 cc installed on my bike,modified roller skate wheel,and chain some upgraded version,much larger (taller) than what was on my first one.
got chain aligned dead on,tension is good and bike runot bad before tuning carb.
here's my issue:
chain is rubbing inside housing,barely marking it,but making noise,moreso under load.
i dremeled away a tiny amount away from the ridge where bearing presses in,
considering adding a small shim between bearing and sprocket.
other than moving sprocket outwards .020" at most,am i begging for trouble elsewhere?
better suggestions?
i guess i could swap in the smaller chain,but i like the whole idea of bigger better chain.
thanks in advance for your help.
