I’m going to be installing some MrRpm parts since I swamped my 650, developed a knock, and now doesn’t really want to crank. Will using their stock crank and rods and an 800cc big bore kit and maybe the cams if I can find someone that can tune it.

If I can’t locate anyone then I’m just going to put it back to stock even though I would like the added power. Seems like the parts would be the same money to go back stock vs. a BBK but I have to find someone that can tune it. I am very able for the rebuild but don’t really know much about the tuning aspect. Any suggestions are appreciated.
