Edster I sent you a PM. I mentioned in the PM that you could bore your jugs to 1250, but youd be better off making a call to NRHS to make sure. They do a 883 to 1200 bore for about $150. But my pistons wouldnt work for you at 1200.

You can NOT bore stock juggs to 1250...............

The largest you can bore your stock juggs is 1212cc....


1212CC is the absolute limit to bore the cylinders... there's just not enough wall thickness to support more

Being a dealer for NRHS Performance I can't boast enough about how great their kits are. I would consider sending them your heads to maximize your performance. I'd hurry! the $700.00 price tag is going up real soon! By the way, Axtell makes their cylinders.
