Hello. I have an Intruder 1400, year 2003 , and i am having problems with the clutch, it works pretty well for a while after the bike is warm enough while riding it for some time for some reason the clutch stops working properly, i have to stop and let it cool down otherwise i wont be able to ride. Usually does this only when the bike is very warm, if i ride it for a few minutes it works fine, I have changed the oil and had changed the DOT 4, any other suggestions… Please help, thanks
