Triumph Top-End Sealing and What the Workshop Manual Doesn’t Explain

By Dave Porter, Customer and Technical Support at The Bonneville Shop When we think of a typical air-cooled British vertical twin-cylinder motorcycle engine, I would propose that the majority of us think of Edward Turner’s iconic Triumph twin. The external rocker boxes sitting atop of the cylinder head really are an impressive feature, and those beautifully chromed push rod tubes are a pleasant visual contrast to the black painted cylinder…

A Primary Concern: The B-Range Chaincase Covers

By Dave Porter, Customer and Technical Support at The Bonneville Shop The Triumph 650 and 750 ignitions and primary drive systems evolved over the years, and along with the upgrades, came revisions to the primary chaincase covers.

Dave’s Building a 10-Footer: A 1970 Triumph TR6R – Part 2

Next in the series shows me checking the air gap of .009” between the rotor and stator, in various positions. I rotate the engine while moving the feeler gauge around the circle, ensuring there is no tight spots.
