416EX Question

[Honda Guy]

Does anyone have a dyno sheet of a Stock 400EX(or with pipes, air filter and jet) and then a dyno run with a 416 kit. Does the 416 decrease reliability at all? I am not one to bore engines but its getting really tempting. How do yall like the 416? Who did it for you? And what kind of racing or riding do you do with it?

GT Thunder's website has lot's of 400EX dyno runs.

I do MX racing,,alot of track riding and some trail riding. You will love the power increase of the 416 kit,,,like riding a different bike.. I highly recommend it,,get the parts from Terry Marcum for the best price. If your leary of boring it go with a higher comp. stock bore piston and different cam. I've read good things about it also..

How much does the 416 kit cost? How much is it usually to intall it?
