Triumph Daytona 500 Rebuild Pictures

INDEX / SITE MAP  CONTACT US    HOME

I decided it was time to re- acquaint myself with the workings  of a 500cc Triumph after not having owned one for over 40 years. I purchased a fairly decent looking 1973 Daytona in September 2011. Cosmetically, the chassis is nice but the engine is a tired out unit with 17,000 miles on the clock, accuracy doubtful. This page shows random pictures of the work in progress, for anyone interested. Comments or questions are welcome and you can email me at sales@northerneagle.ca

Many thanks to Jeff Palmer and Greg Stiles at Palmers Motorcycles in Stratford, Ontario, Canada for the use of their equipment and brains. Between the 2 of them they have 50+ years of experience in vintage and late model bikes of all makes. Indian, HD, and Brit included. Contact Jeff at crackerjackmechanic@yahoo.ca or 519-508-8288.
