Ron Raven (Can Am) autta be along shortly......he is getting twds the end of doing a TR500 (or T500R??) Replica of a period Ron Grant privateer racebike.
Ed Toomey has a rebuildable core for both models of t5oo and gt500. See him on Facebook to or hit me Friday for a phone number when I get home.
have a friend who supposedly had a pile of T500 parts he didn't know what to do with. Let me see if he has it still
I have a fair amount of engine parts left from the last project: pistons, wrist pins, bearings, cylinders, heads, bolts, rebuildable cranks, covers, etc. Some of these are up on ebay, the rest will be within a couple weeks. What do you need?
