both of my brand new engines that I've bought in the last year I had to put a nibby carb on because the carb was either so far out of whack in it's settings that I couldn't get it adjusted in The Sweet Spot to run, or the other carb wouldn't run unless the choke was on, and I don't know how to give it more fuel... it was direct shot right to the carb so both of my bikes I couldn't get to run, checking everything I could, replaced parts and throats, gaskets, all kinds of stuff wasting all kinds of time. I bolt on a nibby carb second pull runs like a champ so I'd have to say Mikuni can suck em. NIBBI FOR THE WIN!
