Hi, I'm a newbie. I got a Yamaha xs360 for helping a coworker clean out and tear down his old shed. Complete, but no title. Carbs off the bike and float bowls removed. Everything appears to be there. I have a haynes manual, but no part #'s. Am having difficulty finding what carbs these are and the correct rebuild kit. ex: will a kit for an xs 400 work? The plan is to build this into a vintage racer. Would I be better off with a different platform?
