It looks like the '71 above was painted Astral Red as a solid color, the primary color on my 1970. It's too bad that they did not do a proper original paint job on it. I have nothing against great custom paint jobs but the original color themes on Triumphs back then were unique to each year and sub-model and identify the bike as such to the knowledgable eye.
A nice 1970 Bonneville just went for $10.5k on BaT last week, looks like mine but probably better mechanicals. Not for long, though. Doing a complete rebuild and learning Triumph engines quickly myself. They are very simple and wonderful. A major shout-out to Pelican Gizmofixer, (Paul), in NJ who has taken time out of his day twice now to give me an education on these motors. I also found a great British bike shop in Long Beach, BA Moto, which has the great parts business, Moore Cycles, just 100 feet away.
I brought my assembled case to BA Moto and one of the owners helped me get it apart with the special pullers and tools they have. These guys are great; they repair, own and race vintage Triumphs plus build killer race motors. They are young and I think they like to drink beer as well.
I've got it apart and the crank is at Marine Crank Shaft in Santa Ana getting polished and balanced as we speak, (one of, if not the best in the USA from what I'm gathering). My P/Cs were worn and had already been bored once to .020 over, so I picked up an Aerco 750 kit which consists of P/Cs, rings and clips plus head gasket. That ran around $630+tax.
Had a couple hours free yesterday to clean parts and get ready to re-assemble the case when the crank is ready. Here are a few photos taken recently. The bike:
