Hi, I took the top end off of my 1972 TR6R yesterday and it looks like I will need new pistons.  Are there any recommendations for a machine shop to do the boring? I plan to have the barrels powder coated, should I do that before I have them machined or after?  Also I have a T160 Trident that I would like to have the tank repainted to stock. Any recommendations for a paint shop in the Detroit area?  Thank you.
