Motobecane vlx help (5 replies)

so heres the story
my buddy has a vlx moby, all stock, works 100% fine
we put a kit on it yesterday evening, everything went smooth, no issues
BUT our problem is, now it wont crank over, u CAN crank the engine by hand, or remove the spark plug and it will crank as normal, it even cranks normal using the decompression valve (yes everything was assembled properly, engine cranks smooth and makes compression as it should), BUT as soon as you release the decomp, the bike no longer cranks.

why?


we are only able to start it now with a drill
is this because the starter clutch is not strong enough to turn the engine over with higher compression and the increased displacement? weve kitted other mobys before and never had this issue...


stock compression was 155psi
current compression is 180+psi

help.
