Well for the past month anytime I went up a long hill and if I had to pass anyone when I was in 4th or 5th gear as I gave it full throttle the engine would rev up. the clutch was slipping and I could not believe it as I only have 25000 kms on it .All the mechanic's I talk to said to either put stronger spings in or change the clutch frictions.. one asked me if I was using car motor oil and I said no I'm using mobil 1 v-twin motorcycle oil. I went back to the kawi dealer and they were no help in the service dept as they wanted to change the clutch to .. So I went up to the parts counter and ask them how much for a clutch as I will do it myself and Mike there ask me why your bike is to new to have the clutch gone so I told him what was happening .Mike told me to to take out the mobil oil and put in Motul v-twin as he said the mobil is to slippery of a synthetic and it will make your clutch slip..I only had 1200 kms on the mobil oil to. well i thought what the hell I will try it before i change the clutch .To my surprise I took it out and rode it hard up the hills where it was always slipping on me and now its not slipping anymore .. go figure !! One smart parts guy thanks Mike.. Has anyone else had this problem?
