After numerous attempts to clean and rebuild my carbs on a 1981 XS400H, I am close to throwing in the towel. I can only get one of my bikes to run on one cyl (the right side), and only start it when full enrichment is on. The other bike (identical year and model) is a similar story. I cleaned them ultrasonically 4-5 times, I even sent them to a chap in Florida and incurred a cost of 300 to get 4 carbs rebuilt with shipping. They are still doing exactly the same as they were before they went to shoot crocs in Florida swamps.
I found a rubber boot from an unknown bike that has about a 1/2 inch offset. I think it might be a CX500 Honda... If I had another to match I think I could mount a pair of Honda CM400 Keihin carbs and just chuck these Mikunis in the swamp.The Honda carbs like the bike itself is soo much better designed...
Also they are easier available off Flea bay and much cheaper to rebuild, and they have a "REAL choke", Also no need to adjust float levels... No diaphragms to fix/replace...
Has anyone else given up on Mikuni and gone over to the VB series of Keihun carbs? If so what did you use to mount them? Also will I need a pushme pullme throttle for the Keihins?

I will try a bit more with the Mikunis as I have 300 bucks into them, but I have no problems like this with my Honda bikes....
