I finished the exhaust today, and only managed to blow through the tubing a few times.
I hooked up the new chain and sprocket, and it seemed to spin fine, so I welded up the last of the motor mounts. The throttle and clutch cables all work with the 500. The alternator plug plugs in too.

My main project now will be the cooling system. I pushed the engine so far forward that I don’t have room to mount the radiator with the fan attached. I may buy an aftermarket slim fan, or consider running it without one (not needed as much living in San Francisco).

Tomorrow I’ll try to tackle the cooling system mounting, and then work on splicing in the ignition box and mounting the coils. I may have this thing on the road tomorrow!
