ALAN SPARKS' PROJECT

Received an email from Alan Sparks out in California. He just picked up an old 500cc Triumph and is looking for help in tracing the history as he restores it. Here's what he had to say:


Just purchased this project bike in Auburn, CA. I was told that the bike was purchased from the widow of the owner who raced the bike out of Placerville, CA. No numbers on the motor although it's a 500cc Unit Construction Triumph. I've been e-mailing back and forth with a guy in Sonora, CA who rebuilds these and he said that triumph motors built for race bikes sometimes did not have numbers on them. Also, the cylinder barrel fins have been drilled out (race application?). In comparison with other motors, it appears to match up with late 50's/early 60's units.


Frame number is AM 405 1556. Don't know the manufacturer (hoping somebody out there will know). Fiberglass gas tank is pretty cool with the dual aluminum flip top caps. Any info on the tank and frame would be nice.
If you have any info that could help Alan, please get in touch.

  1. Just heard from a local flat track racer and he provided some details on the bike. The Frame is from an American Eagle Talon 405 (British MC bike built in the late 60's/early 70's). Frame was custom fitted for the Triumph engine and the fiberglass tank (possibly a BSA Tank). The Bike was Owned/Raced by Paul Knudsen who was a member of the Polka Dot MC out of Sacramento, CA. Unfortunately, Paul passed away in 2003. I've e-mailed the Polka Dot Club to see if there are any pictures of Paul and the bike racing back in the day. If anyone out there thinks they have pictures of Paul and bike, please let me know. Thanks, Alan. Thanks also to Brett for posting the pictures.
