The JC Whitney catalog was common adolescent reading material. I was remembering their "TT Pipes" they had avail for common bikes back in the day. Something cheap and simple like that would be nifty to include in a test stand for running an engine that was not yet installed in a bike.
Yep, but don't put them on the bike itself: the flanges would vibrate, crack, and the pipe(s) fall off, causing a flat rear tire at speed. The rider survived, the bike was mighty expensive to repair.
I remember ordering pod filters, brass swingarm bushings for a cb750, some handlebars and am sure some other stuff way back when. The one vivid memory of that deal was the handlebars looked like they came off a barn find. The were not 'square' but bent and I had never seen such bad chrome before with scratches under it in the metal etc... Sent them back.
Here's the one funny part about this: those swingarm bushings were actually very good, and made correctly for the 750K0-3 & CB500/550K1/2 frames. They didn't fit after those models, though.
I also bought some side covers for a CB750F0 from them. They looked OK, came in gray. About 2 months after I sold the bike the owner came by to have me install a Transistor Ignition in it, and one of the side covers had lost one of the bungs that attach to the frame grommet. When I pulled it off to look at it, the whole cover cracked in half(!). They are still sitting in my garage, I guess I really should just throw them out. I got a new set from Frankenstuff, which are pure gold IMHO.
