i put 3 washers, 1 each behind the secondary belts. New belt installed.

runs great on bottom and mid. I am just wondering if what i did caused something in the secondary to bottom out or bind losing about 5 to 6 MPH.
 

those bolts do not touch once the sled starts moving, they are strictly a starting point for the belt to return to when the primary lets go.
 
is the belt broke in? i put a new one on and was over revving till about 100km's on the belt, then it settled down.
 
i put a brand new belt in then added 1 shim for each little bolt.

it seems to be perfect season before :confused:
 
this is on a 09 4 stoke. factory belt replaced at 1600 miles.

besides the shims in secondary, no other changes were made

Tom, if your bottom out or bind, your rpm spike. You run out that last MPH on over rev.
IMO, Thats something you would feel and see with the tach

Also tends to roll the belt upside down.. not good
