Took my Speedmaster in for the 500 mile service yesterday. The mechanic took all the California smog junk off, installed the AI kit and unifilter, and replaced stock exhaust with the Bub slachcuts. He took it for a ride and found no flat spots or popping. It runs perfect without re-jetting. It's a family owned dealership in San Bernadino Calif. Been there 44 years. They all race Triumphs, even the sales guy.Doug Douglas motorcycles really treated me right and I really like the way this bike feels. Fast and solid.
