426 piston needed

[jr_vw2]

I am in the market for a low compression piston for my yz426. Does anyone know where I can purchase one or have one made? I have been trying to search for it but am not having good luck. Any help would be great. Thanks

Curious as to why, when pump premium works with the stock 12.5:1 ratio, and higher compression is more efficient than lower.

This is very true but boosted engines dont agree with high compression ??

I hope your planning on posting some pics of your set up.
