Cleaned, rebuilt, jetted, shimmed, and resealed.
Took a few hours. Ordered 90/120 jets from CarbJetKits.com. This seems to be the best combo from what I've read on the CX500 forums for running a Mac 2 into 1 exhaust. Shimmed the needle with one shim and filed down the back of the needle to get that wiggle back. Replaced the fuel transfer tube seals and float bowl seals. It was leaking pretty bad before from the left carb. Found a good used intake manifold for the right side (finally) to replace the cracked one. Looks great all together.
Ready to rock.
