I've been a member of the TIOC for more than ten years.
I met John Healy at Triumph Days in Sturbridge, Massachusetts, in 1999. He's been involved with Triumph motorcycles most of his life and is a wealth of information.
The TIOC magazine, Vintage Bike, is well worth the annual dues and I've learned a lot about Meriden Triumphs over the years.
In the current issue John talks about jets and needles for Amal carbs and I learned a lot about after market carb parts that are not made to correct specs.
