I’m looking for a little more power out of my 04’ YFZ450. It’s pretty much stock except for the full Yosh exhaust, K&N air filter/ air box, and the “Cam mod” most people do. Besides a big bore kit, is there anything else I can do to add some more power? Would putting a set of Hotcams in it made a big gain in power? The things got crazy power already, but I figure a little more won’t hurt. This is mainly a trail quad, I don’t race. Are there any other power mods I can do that aren’t crazy expensive? Does anyone make a thinner base or head gasket to bump up the compression a little?
