I noticed that the belt was 1/4 the way off the pulley. Will I need a different tensioner to cure this?

Is the crank bolt/pulley seated.....??????? that could also be the cause...

 

is the belt maybe a bit too long? or stretched?

what pulley is that, stock or ASP? i'd say try replacing the belt with the correct one for your pulleys(even if you originally got the right one) to see if that belt is messed up.

 

If the crank pulley is on all the way to the right torque, you might just need a high sided idler pulley aka the Larry Pulley from Thunder Racing.

I did this a few years ago.

 

ASP pulley. I believe the belt is the right one. It has been fine for 8,000 miles. This problem was after my first time to the track with the DP NOS, so I expected some problems to surface.

I'll be checking the bolt on the pulley. I need to get an SFI approved one anyway, so I'll probably replace the tensioner, pulley & belt anyway.

 

i had this issue with one of those poly cog belts. picked upone of those on accident. kept popping off, then i got a stock belt from the dealer and problem solved. just a thought if you had a poly cog belt that is

Looks like a bad belt. It may have stretched a little on you...
