Motor Work

crzyfz · 11-28-2010, 07:14 PM

I have a 2008 yfz 450 with the Cam Mod, K&N filter, Open Air Box, Jetted, HMF slip-on, 15 tooth front sprocket. I am wanting to do a little motor work to make a little quicker and was wondering what the easiest way to go would be without buying a big bore kit? Any suggestions??

Buy a higher compression piston, stroke it, or both. But first, I would get rid of that slip on and buy a full exhaust. That would really wake it up.

+ one with stuckey. After that you could do some porting too.

Definately go with a port and polish job, with a high compression piston.

Thanks guys. But now could I just do a port and polish job or would I need some more work done as well? I am trying to go and inexpensive route for now
