Ordering Instructions
When ordering at checkout please supply the stamped code on the top of your BARREL CYLINDER* for example, AA,A,B,C,D,E.......P.
This code will provide the internal size of your cylinder/barrel
You will then be sent an appropriate piston sized to match your cylinder. If no code is supplied you will be sent the smallest sized piston.
*PLEASE SUPPLY THE CODE ON TOP OF YOUR BARREL NOT ON TOP OF THE PISTON
Please check your manual or do not hesitate to contact me if you are unsure.
Additional Technical Details
The piston should offer a slight improvement in performance than the original because there are three minor improvements:-
- The piston has an induction curve cut out on the rear offering a better exhaust stroke
- The rings close over the top of the peg which also reduces losses during the stroke
- The piston rings height is raised slightly nearer to the top of the crown.
