I installed a mac underdrive set. Now the belt seems to have alot of viberation. It is making a super loud noise. I didnt know if maybe the tensioner isnt adjusting the belt tight enough or something. Any input?
Will do that. I didnt change the crank pulley. It actually already had an alluminum pulley of the same size on it. Ill check the others though for sure.
do as bentley429 said and also ensure the pullys are flush against the base there mounted to.....you should have tightened all the bolts evenly as you installed...
