New to me GT750 project!

Bought as a project, not entirely sure how uncompromising of a racer I want yet! Anyone know the swingarm and exhaust?

I would guess the exhaust is home made by someone who thought the bike was hiding a camshaft some where. Who in their right mind would make a 3 into 1 straight pipe exhaust for a multi cylinder 2 stroke?

Eh?

Can't remember who , but somebody STILL makes a 3 into 1 chamber for these. I think they're designed for low end torque , not top end squirt like a NORMAL 2-stroke owner under the age of 80 wants.

Seeing as this engine will be set up for touring, then I think I will be quite happy with the exhaust. May go for the original airfiltersetup too!

Exhaust looks homemade to me too. The water buffaloes had a flat torque curve from the factory. Not peaky at all, like say an H2.

Can't beat that triple sound with chambers and pod filters.

The Yamaha is almost done. I couldn't bear the thought of not having a project :)

It really only needs a wheel laced.

Jemco out of Houston I think will make a 3-1 or 3-3. I was told he makes Omars 3-1. A 3-1 is going on mine when the funds allow. Does good work too.

The chambers on my GT-550 roadracer were Jemco's..... provided without the cones assembled, to they could be pie-sliced and welded for best clearance. Depending on how 'custom' ya wanna get, the TR-750 racer's center chamber went high on the left, through the frame, and exited high on the right. Left more cornering room below.

I stuck with all three chambers low, and lifted the bike at both ends by 1-1/2 inches. She wasn't lightning-quick steering, but still plenty stable.

Good luck!

I'd love the TR750 pipes, but tuned for standard porting. That would be one hell of a project though!
