Ease of Installation
Not great

I bought the kit for a 1999 YZ250. The base gasket, power valve, and water pump gasket all fit well - but neither of the head gaskets were correct. The YZ utilizes the O-ring style for the head. The outer ring was too small, and the inner ring was too big (both in circumference, not diameter.) I had to go a different route for those two.

Ease of Installation
Just what I needed!

Perfect fit, and seal. Cost efficient necessity for a tear down and rebuild.

Answer: We don't offer different size gaskets for your bike. I would suggest contacting Wiseco to see if they offer something other that the stock replacement gasket kit.
