I ripped this off of the thread I started back in the day:
http://www.talkmorgan.com/ubbthreads.php/topics/200545/all/Belt_noise"DO NOT “OVERTENSION” BELT
We at Super Max strive to give you excellent belt drive products. We perform many pulley rebuilds. Each and every Over-Lay is hand cast and hand machined to exacting specifications to fit the need of each and every customer’s personal requirements. We have approximately 6 painstaking days in each Over-Lay to insure that you, the customer, are getting the very best possible service and parts.. For “YOUR” motorcycle.
The average rear belt is “SEVERELY” Over-Tensioned. This extreme tension can cause a myriad of problems with belts, pulleys, bearings and seals as well as premature belt failure. It is best if you have some play in the belt. On swing arm bikes 3/4” with two people up is a pretty good starting spot. If the belt does not ‘Ratchet” (Slip a cog) it’s not too loose. Over tensioned and misalignment must be addressed.
Give your new Super Max a break and utilize a looser belt tension than is common on many bikes. The over tightening of belts can cause premature failures.
Your Super Max pulley will last you for years if properly cared for."
I don't know just when this will be installed as the third pulley is just starting the self-immolation process. I can probably get a few thousand miles out of it before it becomes obnoxious. It's still a hard winter here and I don't even expect to be able to take it on the road before the end of April! grrrr
