Which is why I didn't bother to fit the ones I bought and are now on someone else's bike with similar bother. IMO the best conversion on Ducati SSs is the Dellorto carbs.
Not heard of these as an option, some rave about the Mikuni flatslides, but they are not as common. Had I known of the Mikunis at the time I may have considered. However, hindsight and all that. I have to say the Keihins, in conjunction with the other mods, are very very good now they have almlst been set up right. The power improvement across the range is noticeable. Its just the idle which is still not right. Stuart at Ian Murray has not changed the jets, I am sure that with the full system the air flow is too great for the base idle fuel jet, leaning out he mixture and causing the symptoms I have. I have the jets, its my plan to do this tonight as I was too busy yesterday, I will report back...
I have a cure............ Fit the Mikunis with stock jets other than Dynojet 155 mains and Needles / springs
Ok, 65s dont work. Its almost as if its a vacuum leak. I can see why people get rid of them. Patience
Ian........Have a read.........maybe there is something simple among all this lot that will help. carbkie.html, Keihin FCR Carb Tuning Procedures Fixing the dreaded lean bog on Keihin FCR carburetors http://www.keihincarbs.com/tips/gate.html Keihin FCR tuning manual * FREE * - Frank!

No apparent vacuum leaks, sprayed easy start all over. Do you think its worth putting on the Standard Mikunis to check if its the carbs?
stronger throttle return springs might help been watching this thread with interest reminded me of an old bike I had when I was younger revs coming back down slowly turned out the throttle slide springs were not strong enough and the air flow was keeping the slide from dropping correctly just a long shot I am not familiar with these carbs and quite glad I have the inferior injection system sometimes
Ok, I have returned the slow fuels to 60's and its running much better. I have played about with adjustments a little and its running about as good as ever. Revs not hanging nearly as much as before. So Im leaving well alone and see how it goes before winter kicks in.
