The standard spec includes a spark arrestor to meet US Forestry regs---but I guess they meant leaves etc being caught up under the low level exhaust system and catching fire there.
Otherwise known as the patented Triumph system to make you go like hell so that the velocity puts the fire out!

In answer to your Jackpine question, that is a common moniker for the 66 T100C, so the exhaust referred to would just be the stock siamesed high pipe for that year.

Which doesn't work as stock on the TR5T, due to the close proximity of the downtube to exhaust port. They must have altered it to fit, or just never mounted it (maybe why you didn't see a picture?).

I'm surprised a Michigander isn't familiar with that term for that bike, Bill Baird was probably responsible for it being called as such. Though I don't know if it was ever an "official" designation, probably just a popularized magazine dubbing.

I've been referring to the 66 T100C as a Jackpine since, well, 66.

I grew up riding Poker Runs and Enduros and spent many years riding in the woods up by M 61 in Gladwin. I did not know if it was a official model or if they had put together something special for the race. I did some web searches and it looks like it was a unofficial nick name for the early T100C.

Continuing the topic drift for one more post, in looking at the 1966 Triumph USA sales brochure, it does refer to the T100C as "the famous Jack Pine" model.

Don't know if that makes it "official" or not, or if it would apply to other years? But it certainly does to the 66.

OK, back to twisty pipes... I have looked at one bike with the 66 exhaust, but the right side was altered to fit, something was changed with spigots, and the engine had to be removed to mount the pipe. Musta really wanted that look...

If you look on www.dcclassicmotorcycles.co.uk Dave does/did a few different pipes for the TR5Ts & the Triumph twin based pre65 bikes he builds, there's a few ideas there?

Wearing shorts in any bike is tempting fate

Let alone that the world is not ready for my legs

An old post, but a Google image search lead me here to comment on what was my bike when this picture was taken. It was 1982, Lexton Road in Mitcham, the fella is Mark who I have known since 68 and am still friends with, his C15 I sold to him. As for the Adventurer, I had just rebuilt it following an accident that saw me in plaster for nine months. The bike needed a new frame which I got from Robucks. The exhaust system is Triumph T100C, and the whole lot was genuine, not pattern. the only issue was the R/H pipe, I had to put a small dent in the front else it would have touched the downtube. The red thing at the bottom of the downtube is a Norton Commando oil filter which I used for a while following the fitting of the new frame which I also had stove enameled in case it had anything harmful in it. Though it looked nice, the original exhaust system was actually better performance wise. The wheels were brand new on Borrani rims that Hughes of Tooting had built for racing but never used, cost me about £30, I couldn't resist at that price, so I would use them for the road, and the originals off road. After rebuilding it however, it was too nice to use off road, so as all that was wrong with the frame was the seat loop, and a dent in the tank, and I had the spare wheels, I just bought a spare engine and built another one for the dirt. A French site found some of my pics, I am wearing the blue and white helmet riding the one I built from the accident damaged parts. (See link). Three of my friends also bought Adventurers and a Trophy Trail as they were so impressed with mine. Pete Charlton http://twist-grip.blogspot.com/2013/12/
