Re: 62 Triumph Bonneville

Well, Things are in a holding pattern right now. The old heart backfired so I'll be shifting gears for a while, taking it one day at a time. Nitro under the tongue ain't near as much fun as in the tank but we will adjust and get going again soon.

Re: 62 Triumph Bonneville

While waiting on some parts and a schedule to pick up the tank and fenders I've started on the next project, the old Vinnie. Twice as many part and much more complicated than the Bonnie so it will be a challenge for sure. Vinnie.jpg Three days of disassembly and cleaning and into the heart of the be...

Re: 62 Triumph Bonneville

Did some research and also called a guy who has restored a few Triumphs. I was reminded that 62 was a transition year from the last pre-unit to unit construction. During this period some parts were being mixes to say the least, including cams. Rather than pulling the head I set up some indicators to...

Re: 62 Triumph Bonneville

Back on the project. Next is setting the valve spring pressure and stem length from the head. If it's too low or too high, the rocker will not hit in the center of the stem. Usually after a valve job, the valve tip needs to be ground to correct this. Next is checking the valve springs in relation to...

Re: 62 Triumph Bonneville

Everything was going well on the head until I put the wrong stone on the seat grinder. I had cut the 30º angle with a 60º angle stone. :oops: Well my option at this point was replace the seat. First problem, these seats are cast in place and not necessarily concentric with the valve guide. Most comm...

Re: 62 Triumph Bonneville

Got some winterizing done so back on to fun stuff. The elbow grease paid off and the primary cover finished nicely. The small dent is not visible since it goes behind the footrest so I'll let that slide. 20181007_181946.jpg The speedo and tach are finished. Kinda sticky even after cleaning so I've o...

Re: 62 Triumph Bonneville

Yesterday I delivered the tank and fenders to Young Pon in Bellingham. He was referred to me by Bill Stevens, President of Washington Vintage Motorcycles who has had several bikes painted by YP. His quality is top notch. He also has a small collection of vintage bikes from Bultacos, BMW, Nortons, Gu...

Re: 62 Triumph Bonneville

The engine is finally in the frame and all the correct bolts, studs and nuts are in place place but nothing tightened. 20180922_181346.jpg Next was fitting the push rod tube seals. The process normally calls for a .030 crush fit. Anything more than .040 can warp the head. After double checking every...
