There is a guy out here on the west coast in Bellingham, WA  Located in the NW corner, who does the same, so no competition I hope. Great prices. He bored, chamfered the ports, supplied the new clutch nut, rim locks, I needed for my '73 MX and tuned of the trueness of my crank for $120 USD incl. taxes. Cycle Therapy.
