Nice Gasket
I bought stock and this one. They both fit well and I honestly couldn't tell the difference between them except for a very small difference in price. Works great though!

Tusk Top End Gasket Kit

91 YZ250
Great price, and good kit however the gasket for the reed cage is a little too small, and will tear at the corners when installing. I used this kit on my 91 YZ250
