Best practice is to replace the gasket when you remove the cover. Reusing old gaskets often leads to slow leaks around the cover bolt.

Easy to install. Good quality and price. Does what it is supposed to do
Very good quality/value for the price, I would buy them again.
Good gasket, I like these because they are the same thickness as factory, and do not change the end play on the cam and breather
Decent gasket. Sticks out of the nosecone cover a bit at the top as it doesn't follow the nose cone shape precisely. Seals well.
easy to replace just like oem
