A preliminary once-over shows it will need a few things like brakes, new bars, and cosmetic work - lots to do. But before investing any serious time or money I want to make sure it runs. So job 1 was to check out the carbs. Sure enough, one of the diaphragms was torn so it was back out to the shed to pull the carbs off bike no. 3. I was in luck; one of the diaphragms was still good (the second was also torn). This was good news for a number of reasons, not least of which is replacement throttle slides with diaphragm can run upwards of $150 each, used.
Cannibalized a few other carb parts and now I have a complete carb setup that seems in good shape.
The proof will be in the running, of course.
So now it’s time to put enough of the bike together to hopefully (fingers crossed) get it running. With the crappy weather forecast for the next few days perhaps I’ll have some good news in a week or so. Wish me luck.
