What I'm trying to find out is if anyone out there locally can balance the crankshaft to the piston or vice versa. I'm building a 1300 motor based on the M1000 bottom end, and the more I read and think about it, I'd like to have someone re-balance the crankshaft and piston (since the big bore will have bigger and heavier pistons than the stock M1000 pistons). If you know of some local shops that can do it and also if you have had experience with them. I'd obviously like to find someone who knows what they're doing and have it done. Thanks!!
