I see many hardened, near crystallized, flattened, corroded carb orings. Some rail orings right on the verge of becoming intense leakers. Mikuni (used on early 2V Ducati) not immune either.
Yeah those o rings have lived a hard life on my bike lol. I'll be sending my carb your way in a couple weeks just need to find a good time to get them off. Curious to see how much better they'll run to once theyre properly cleaned (they've never taken apart).

In the process of doing the equivalent of a 15,000mi service on the bike, so basically everything's being looked at
