I sent my 650 to Mike Rieck and he did a beautiful job. I had him do a bunch of performance stuff too. Highly recommended. Nothing against Hondaman of course but Mike is in my backyard and is known nationwide for these SOHC4’s for his work, including porting. Can’t go wrong with either though. I think Mike would be closer to you since he’s in Mass, so shipping would theoretically be faster and cheaper.
