engine balancer ?

[Slingshot560]

on the quadzilla, clutch side, i had to remove the balancer to put in a new keyway, now all back together it still vibrates like a s.o.b, is there a certain way the balancer has to be installed, it spins freely until you put the gear on it then i dont know if it has to be in a certain way ???? please help, this shit is drivin me nuts. that and these stock carbs are pieces of junk too !

i would just make sure that the balancer isnt bent. Our Lt250r was vibrating like a SOB and we found out that the balancer shaft was bent.

is there play in the bearings? i just had my lower end rebuilt on a lt250r and now it's smooth as can be. if any bearings are bad including the rod, it will cause vibration

put the engine on top dead center. youll notice a dot on the balancer gear and the crank gear they must line up or you will get a vibration.
