Ok im rebuilding my 2000 mxz 500 ordered a rebuild kit off ebay put it together and left it sit till now went to start it and piston is hitting head. I did looking never knew there was different thickness of base gaskets but the highest the go is 0.8mm and my piston is sticking about 1.5mm over my cylinder right now with paper thin basr gasket. So my question is how much should my piston be sticking up on my cylinder i thought its expose to be flush with top of cylinder and if so how can i make up the room I need?
