68 t100c teardown and rebuild

Well, I picked this bike up in the spring and it is a nice runner, but it shows 40 years of rust. I had a few issues running it this year, mostly minor, but am going to tear it down over the winter and see what I have, mostly concentrating on getting the frame touched up and the cosmetics updated. Have not decided on the engine. Liek I said it ran nice, started easy, the only issue i have is some oil on the left side cylinder head after being driven, it would burn of and be fine while riding but after sitting in the garage on the side stand it would build the oil back up on the cylinder fins. I did a carb rebuild and new air cleaner late in the fall when it started to stall out on me, and it ran fine after that. Tank is currently out at the painters being restored to the original 'Trophy 500'. We will see how it goes.

frame done

well the easy part is done, I have the motor out and the frame torn down for powder blasting or painting. No huge suprises, mostly rubber gaskets that need replacing, cleaning polishing, some bolts to replace, but generally everything was in pretty good shape. The oil tank had been repaired with some fiberglass, see the photos, so I am seeking a used replacement, as I am not sure I will be able to blastg and repair this one. Next will be the motor teardown.

been too long since I posted, have the bike torn down, lots of rust and age on the frame and bolts. tore down the forks, had a heck of a time getting the dust excluders off, and then getting the oil seals out, they must have been in there a long time. Brute force was the final answer after a few days of alternate soaking in WD40, PB penetrator, and the stanchions were pretty much shot, see the 3 pics, so I have replaced those and the oil tank. Am waiting to get the frame and various pieces back from the powder coater and get started on rebuilding the frame.

Isn't amazing how good a bike looks from a few feet away!

It's only when you start taking apart that the true condition becomes evident.

You've got an interesting project on your hands and we look forward to watching your progress.

Good luck!

Imagine how good a bike looks to someone hot to buy a bike before summer and it`s not hard to see how so many guys end up with repair and rebuild projects rather than rideable bikes.

I`ve never been dissapointed buying a rolling basketcase yet because I know exactly what to expect.

Good luck.. I'm in the same position.
I got two Daytonas.. a 71 and a 72.. hoping to get a runner from both, but didn't realize how much work I set myself up for.

Actually, one engine is stamped T100C and the other is T100R.

I'm learing a lot.. and having a (PB) blast..

is there a specific orientation for the swing arm spindle grease holes when replacing the swing arm shaft? do they align vertically, horizontally or does it not matter? I don't remember how they were when they came out.
