Dear Lunatic: Man, I've always wanted to say that! I'll just have to say it again. Dear Lunatic, if you don't mind shipping your engine, I'd recommend Don Nevins as a mechanic! He's a great mechanic who specializes on old Brit bikes and he's honest and laid back. I've always found him very forthcoming with information and easy to deal with. Don works out of the same facility as Randy Baxter of Baxter Cycle and Randy deals in old Brit bikes and parts all over the world, so parts should not be a problem if you need any for the rebuild. They are located in Marne Iowa. Don's number is (712) 781- 2451. Hope this helps! Good Luck.
