Fit perfectly and stopped my leak. Simple things that work like they're supposed to make me happy. Tusk is my go-to for value.

Worked out great part in picture showed it had exhaust bridge holes in the piston which it didnt . But came with instructions on how to apply them wasn't to much of a hassle over all satisfied.

only complaints I have with the kit is when you need to refill a size it gets pricey real quick buying the shims individually. Not sure why you have to go through hotcams to get each size in a small bulk package for a decent price. The other complaint I have is the numbers on these get very hard to read after some ride time. Still a handy little kit.
