Where you located? RB parts sometimes hard to find. Rayaracing does resize the sleeve. there are trick on resizing you can find on the internet. I'd just purchase a new piston and sleeve especially an RB product.

Ok thanks I am not sure how to tell if it needs it. Or not.

How many liter or gallons has it ran?? I've been running RB since the mid 90's. I've seen them 4gallons of fuel or 2 1/2 season of racing , 2X a month, b4 recondition. Check compression by hand, pinch start at approximately 270degrees from TDC, should be restriction by hand, or purchase a RC compression gauge.
