Haha, Toomey pipes would be awesome.....  Evil There were accessory pipes available for these, but apparently they've all vanished off the face of the earth like most of the bikes.

I ran across these pics a while back online.....if mine hadn't been complete, something like this might have happened.

I'd consider coming out of retirement for that. Tongue

The old girl cleaned up pretty well. She's got too much precious patina to violate it any further than my thorough cleaning. waytogo

Recover seat, check. Fab new battery cables, check. Verify static timing, check. Test for spark, check. Fab and fix missing rear gas tank mount, check. Test for gas leaks, check.

When I went to check for spark, it was pretty damn cool to hit the key and have all the lights come on for the first time since 1981. All signs point to this thing running as soon as the snow is gone and I can get it outside. If it runs well, about all it will need is tires and plug wires. Game on.


This really came out nice!  I don't know much about two strokers, does this just not have expansion chambers?

They're weenie little muffler expansion chambers, not proper pipes.

But actually they're just fine for this moto.
Don't really want to be torturing the engine with more HP as replacement parts must be thin on the ground.

I suspect the entire cylinder is cast iron, yes?

Well, if a magnet sticks to it, it has iron of some amount. So that covers iron, steel and 400 series stainless steel, among others.

Iron would make the most sense.

I'd add 347 stainless.

It's far from a complete list but I didn't know about 347

I ran into it when I was working in the fab shop.

They used a big piece of it in a camera base they made for the Smithsonian. I just painted the thing. The whole weldment was 8 feet across.

Yep. Replacement engine parts for these are slim to none, even from the one place in the US that is considered the source....

The cylinder is indeed cast iron.

 Cool

I've been buzzing around the neighborhood on mine here and there since the initial resurrection. It's sorta fun to ride even though it's not high powered by any stretch and cable operated drum brakes are plenty sketchy. Part of the fun I guess. Going to get some tires ordered for it soon, since it's going to need to venture out on the road as it should.
