Common questions
What does .010" oversize mean?
This ring is sized for cylinders bored .010" larger than stock 883cc specifications. Your cylinders must be machined to this dimension for proper fit.
Is this a complete ring set or just one ring?
This product is a single piston ring set. For a complete engine rebuild, you will need to order enough sets for both cylinders.
Can I use these on a stock 883 with original bore?
No, these oversize rings will not seal properly on stock-bore cylinders. They are specifically for cylinders that have been bored .010" oversize.
