British Bikes / Exhaust Pipes for TriBSA
« on: March 30, 2020, 04:19:33 PM »
Hello, I’m new to this forum and I have a TriBSA I originally built more than 50 years ago using a CB32 Gold Star, frame No. CB3385 and a 1952 Tiger 100C, engine No 31540. I blew the Gold Star engine up chasing a 305 Honda.
Like a lot of youngsters of the day I fitted a racing seat, racing tank and I made a central oil tank. I also fitted a TR5 high level Siamese exhaust system and Royal Enfield front forks.
Since I retired, I have been slowly rebuilding the bike, using the original tanks and seat etc. I also want to fit a normal low level Siamese system, the TR5 does not fit that well with the tool box being fitted.
My problem is getting one that fits, the Siamese high level fitted with more than 0.312” clearance from frame down tubes.
Can anyone advise of suitable pipes please? The exhaust stubs are 1.5” dia, I could fit sleeves to accommodate 1.625” dia. Pipes.
Thank you
Regards
