thanks for the response, the belt is 47 1/8 and it is between 1 1/8 and 1 1/4.....did it wear down from 1 1/4?.........how can you tell if the belt is worn too much?.......it looks fine to me, it is dirty and you can see a couple places on the outside that have slight wear....the belt may have 100 hours on it......the clutches are 13 inches apart measured from the ouside bolts, i wanted to go another 3/4 of an inch forward to tighten the belt ..... i can pinch the belt together right behind the drive clutch and almost touch the top and bottom together...........would a new high performance clutch make a big difference?........thanks again
