XR100 racing camshaft and high compression piston

What do you guys think of your high compression piston or racing camshaft. Is it worth the money or should I put my money into a different part.

The thing that will make the MOST difference is a high compression big bore piston. Everything else adds a little here a little there and adds up, but there's no replacement for displacement. Cam, big valves, pipe, porting, carbs are all great but without a big piston, they can only help so much. Of course, I'm talking about making power, not just having the engine run a little better.

hondatrailbikes has a nice 115 kit thats just the ticket for the right price check out the web site!
