[kobiparts]

Hi

i have an yfz350 , bought hot rods 4111 crank 
and Athena 392cc head kit

but i need new pistons that will fit those two parts, the crank and the cylinder kit.

Thanks.

WSM has decent big bore options and you might need to have that head worked as well as the ports if it's originally a kit for stock stroke.

The Athena cylinder is 68mm and all the piston I found on eBay is 66mm.

Any chance wsm has an 68mm with long rod piston?

Yes, that's why I posted their name. TDR stocks them.

Thanks a lot!

Hope they fit well.
