I fitted the cooking Comets Mikuni with a length of water hose (some blue quality stuff Ben uses on the flying brick) and the carb stopped falling off!
Today I took a ride on a sunny and average spring day in UK after about 20 miles I opened it up and it misfired and faltered and as it was a slow traffic situation I continued on pilot and minimum throttle until I reached some straight road near to my destination wound her open again, and she did the same trick and then after 20 seconds just as I was about to give up, she cleared and ran smoothly up the revs I thought it was a rubbish blocked jet that had sucked through, but when I got to my destination the outside of the carb was running with....water. I cant believe I was getting ice in May, if I was that hose is some insulator.
