That will be cool when done. I have a little TC100 that I got a few months ago for $50. It is held together with paint and rust but it was cheap and it runs. FAR beyond restorable but still a fun little ride.
That TS185 is a solid bike. Had one that was the farm bike for years. We'd pull it out of the barn every so often and ride it. Put it away for a few weeks/months, pull it back out and it would fire right up.
Lots of fun.
Good point. That bike will be pretty light when complete, I bet a stock cb350 drum would do the trick just fine. I'm sure you would have no problem finding one from somebody here. All the 350 racers have take-offs.
I'm sure something like a CB350 brake, or if you want to stay Suzuki a GT185 or GT250 brake will be more than enough. That little enduro brake will probably be good for one medium stop before totally fading out (if you are lucky).
