Any comments on this link?

 

my 96 Fatboy is 3/8 ~ 1/2in

 

Thanks!

 

Grab the belt with your thumb and forefinger where it is accessible on the upper part headed to the transmission from the rear wheel and attempt to twist it.

It should twist about 45degrees. Do this with the bike sitting on it's side stand and normal load. Less that 20degrees is to tight, 90degrees is to loose.

I've used this method since I purchased my bike and got 115,000 miles out of the belt before it broke. And it broke because of debris that peeled back the protective rubber coating and allowed the steel belts to rust. Both pulleys are still serviceable and were reused with the new belt.

 

Thanks I like this method

 

Check your lower belt guard mine has a gauge built in, each line is 1/8 inch.
