I'm planning on replacing all my gaskets and seals on the top and bottom end of my bone stock '98 honda 300ex engine next weekend. I've been thinking of getting a wiseco over bore piston kit, which I'll put in, if I decide to, when I replace all the gaskets. The ones I was looking at range from .010-.080" over stock. Do I need to replace/mod anything else on my quad to install the .080," such as valves, springs, cam, sleeves, or anything else? And if so, are there any sizes that won't require that? Also, do they increase wear on the engine, tranny, etc. or have any other problems associated with it? Also, any recommendations for a specific over bore piston kit to go with. Thanks for the help.
