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…
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. The beautifully cast covers are one of the most prominent and eye-catching components on the unit-construction Triumph twin engine. Unfortunately, they are also vulnerable to damage and corrosion, so original primary covers in…
The Importance of Right to Repair Legislation By Mike Grage, Customer and Technical Support at The Bonneville Shop On February 2, 2022, H.R. 6570 was introduced to Congress and was referred to the Subcommittee on Consumer Protection and Commerce. It has not moved since. If passed it will become the Right to Equitable and Professional Auto Industry Repair Act. This bill may have automotive industry in the title; however, it…
By Dave Porter, Customer and Technical Support at The Bonneville Shop The topic of which oil pressure switch to select regularly comes up in discussions, and still remains somewhat baffling as to why there are so many inaccuracies abounding regarding this simple switch. From late 1968 onward, BSA and Triumph used an oil pressure sending unit which has a small internal plunger that senses oil pressure levels. The switch is…
Pattern Parts and Fettling to Perfection By Dave Porter, Customer and Technical Support at The Bonneville Shop Occasionally I receive inquiries from customers stating a part that was purchased from The Bonneville Shop does not fit correctly. I typically query the customer about the application, including make, model, and year. Sometimes it is revealed that the part was ordered in error, and the result is a simple return of the…
By Mike Grage, Customer and Technical Support at The Bonneville Shop We didn’t have LEDs when I started professionally wrenching on motorcycles over 30 years ago, but I most certainly wish we did due to the low power requirements. Done right LED lighting can make riding a battery less bike at night much safer. People of all skill and knowledge levels tend to have difficulty making LED turn signal lights…
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. The rotor was in good condition, no “runout” on the end of the crankshaft, and the stator studs are not bent, so this procedure passed with flying colors. “𝙄 𝙝𝙖𝙫𝙚 𝙖𝙙𝙟𝙪𝙨𝙩𝙚𝙙 𝙩𝙝𝙚…
Have you thought about getting an old barn bike to fix up but feel like you don’t know where to start? Are you thinking that you have a smaller budget to get it back on the road? No worries, mate. Sometimes it’s great to restore these Brit bikes to their original glory but sometimes you just want a cool bike to enjoy the roads on. Dave has picked up his…
How the Tiger 100 Became the Daytona By Dave Porter, Customer and Technical Support at The Bonneville Shop It was brought to my attention recently while updating Triumph 500 valve product descriptions in our catalog, that there should be a blog to help illustrate some of the history and evolution of the mighty Daytona Tiger 100. Bert Hopwood and Harry Sturgeon were becoming increasingly concerned in 1965 about the forthcoming…
A Farewell to Real Chrome By Mike Grage, Customer and Technical Support at The Bonneville Shop I remember a line in the movie Mad Max: Fury Road “…You shall ride eternal. Shiny, and chrome!”, and then the silver paint is sprayed into the guy’s mouth. That silver paint might be the near future for motorcyclists and gearheads (petrolheads) like me thanks to government bans. When I started riding motorcycles on…
