I've got a True 11:1 Ross piston for sale. It has less then 3hrs on it. It's designed to change the bore of your Yamaha Raptor to a 686, and still run 93 octane pump gas. No problems with the piston, it has been lightened and de-burred by Bob Craycraft at Craycraft racing. The bottom of the piston and skirt have been heat and friction coated. The piston is clean and in good shape. Only taken out to install a 13.5:1 Ross and start running 110 race gas.
If you are interested PM me or email me at gytr_660r@yahoo.com
This piston is not the JE style piston that people have had problems with, this is a new Ross Racing Forged Piston. I will sell for $175 shipped to anywhere in the US.
