The only 12:5 piston I know of is woods...

It is a nice piston by the way..

 

randall(222) says its a lead weight. what do they have for compression 12 or 13-1?? who sells them.

 

Woods has 11:1 and 12:5 pistons. Yes they are not as light as the je pistons that hpr sells, but they are not a bad piston especially since they are only $250 or so...

 

ok thanks amd! are you comming to genoa?

 

no, I cant make it to genoa. I am getting ready for little sahara on holloween weekend.

 

JE is supposed to have thier own superlight piston, similar to the "Ringholder" design on the YFZ 450 and 450R. It's probably another 2-4 weeks away. Wisco has also started making superlight pistons now for the 400EX.

 

how do the super lites hold up?

 

someone told me that a couple have broke. dont know any details
