What is the next size up from stock. My cylinder is scored and I'm wondering which size piston to get. 101mm?? Are the bore and clearance specs included with the piston? Thanks in advance!!!

 

I think you can get a piston that is 10 or 20 over and there is a 101mm also. Pistons should allways come with clearance specs.

 

Scott- I believe JE finally made their 101mm piston. Check with them or Craycraft on availability!!! All specs should be included like sixsixT said!! Put that puppy back together and let's ride!!!!!!!!!!![img]i/expressions/face-icon-small-happy.gif[/img] If you have any questions call me or PM me. Laterz Rigo

 

On the JE piston, remember that recommended clearances are "per inch of bore". If not looking for more power, the OE (oversize) piston is the way too go set up correct of course. Why is your clyinder "scored"?

 

My cylinder was scored when my valve broke. There's a couple of shallow grooves in it that cause it to need bored.
