Stripped the carb's down today to see why the K1 was running rough from idle to partial throttle. All the float levels were way out, but the main problem was number three carb main jet holder is bent, it felt odd unscrewing it (slack, tight and so on) and the needle end was taper ground to make it fit. This bike is a recent American import.
My problem is getting hold of one as David Silver doesn't seem to stock them, any ideas anyone?
