On the post 99's, the relay is under the headlight just in front of the triple clamp. Easiest to reach under the headlight from the front, very accessible. I'm guessing the carbies are in the same area. I tried to cross reference it at NAPA, but I wasn't confident they had it right, so I spent the extra money at the dealer when I replaced mine. The electricals are already somewhat fragile on these things, I didn't think it was worth trying to save the few bucks.
