Big Bore

8 posts in this topic

<font color="navy">Does anyone know where and if there is an aftermarket big bore kit for the YZ426? I'm not interested in boring or resleeving my cylinder; I'd like to find a complete big bore kit. Thanx

What the heck you you need MORE POWER from a 426cc four stroker for?!?!?!?!?! Oh, to keep up with the KTM 520's! :D

Just Kidding!

<font color="navy">You can never have enough power :) If you think the 426 has gobs of power, try a CR500 before they're gone. FYI they've stopped production of the CR500 for 2002.

Has anyone played with a Wiseco 13.5 : 1 compression ratio piston (stock displacement)? I understand you're suppossed to run 50:50 race fuel/premium. Is there a big difference from stock?

Thanx for your replies

Hick from here did the 450 kit to his bike and last I heard from him, he really liked it. You might do a search on this since he has posted about it here a while back...
