I have a 1972 T100R, JG 32552 (August 1971-July 1972 is what I found in one record). I am trying to find out some history on this bike, if possible. The bike has no directional signals and does not look like it was ever wired for them. The left handlebar control is a horn and the high-beam/low beam combination switch with the horn. There are no right side controls except for the throttle and Air Control Lever. The triple-trees are chrome along with the headlight ears and front-end sliders, it does have gaiters. The bike also has a steering damper. To the best of my knowledge these parts look all original. The chrome is pitted in some locations and is tarnished in other locations. However, searching on T100R images and also in the Haynes Manual I cannot find one of similar design features. I am starting to think someone just chromed the frontend many years back. Does anyone have any insight if Triumph manufactured any chrome frontends such as the one described? I would like to do the rebuild as close as possible to original. Thanks for helping, David

I think you're right about the chrome not being factory. All my reference material shows the forks and triple trees in black paint, top to bottom.
The handlbar controls sound right.
The bike should have directional signals from the factory.
The steering damper was dropped in 1970. I think the front end has been replaced with an earlier version.
Hope this helps.
If you have more questions don't hesitate to ask. We may not know everything, but we'll do our best to help.

Hi Rocky and thanks. The engine and frame numbers match and the bike seems to be mostly complete and runs ok. I plan on doing a complete rebuild and a wire harness is on the list of items so I will ensure I get one which includes directional indicators and start looking for the correct hand controls. I am familiar with the Honda CB series and have done rebuilds in the past. I am new to the Triumphs, I always wanted one and I was just able get one that needs work a few weeks back.
Since you are new to Triumphs you were wise to get a bike that was complete (or nearly so) and running.
Sounds like you have the basis for a great restoration. The 500cc bikes run well and are satisfying to ride unless you're a WOT road burner.
I'm a firm believer in replacing very old wiring harnesses. Electrical problems can drive you crazy.
Good luck with the restoration.

How about a few photos of it that would help
Wow, the bike looks really good!!! Just from the pics, and overall, you got a good one.
It's all in one piece and running. I think I would ride it as is for a while if it's roadworthy and you can trust it.
FYI, where there is yellow, it should be cherry, but the scheme on the gas tank isn't right, according to the pics I have.
The fenders have the correct white stripe, but lined in gold.
But you may already know all that. I just thought I'd toss it out.
Everyone here will be anxious to see the finished product.

That bike looks in great shape
Those are threaded plugs with O-rings to fill the holes first put there on the 1971 models so you can feed a feeler gauge straight in when adjusting the valves. This was long overdue as prior to that for all those years it was a PITA to try and use a feeler gauge to set valve lash.
Cheers, I've never seen those before.
I've done the valve clearance on the "plug-less" Triumphs more times than I can remember and have become accustomed to working through the round inspection holes.
This younger generation has life so easy.
Headlight ears, yokes, fork lowers and pillion peg mounts should all be gloss black, not chrome.
That is one sweeeeeeet bike you have.

I do not know any engine rebuilders up your way. The Seeker may know of one. If you have to end up shipping it, I recommend GrandPaul right here on the forum.
As for paints, Don Hutchinson is the best U.S. source and authority. However he uses the original paint types that most modern paint shops refuse to use. www.triumphman.com
Don Hutchinson, under encouragement from up-and-coming staff members, now formulates ALL original Triumph colors in modern paint. He's moving with the times!
Ah, that is good to know. Thank you, Paul.
