just wondering if someone knows the minimum width for an 02 -400 kodiak se drive belt mine is not slipping yet but it is lossing top end speed

 

Theres almost no way the belt will be worn. This tranny is nothing like a kawi or polaris. The belts only slip and wear, if its been wet.
This is the classic, primary clutch weights needing relubing. Clean out the inner area of the primary, all the old grease, and dirt and grit , and relube the weights, and itll run like new.
The belt should be between 1.21"-1.09" wide
