I just purchased a used Aprilia. It is a 2002 RSV 1000 R Mille, the lady I bought the bike from told me that she had just had a shop install a new clutch, tires, etc. The clutch appears to be very stiff, and hot or cold it will not go into neutral with the engine running, I am forced to hold that strong clutch in at every red light, very aggravating. there are no external adjustments for the clutch that I can see. Also, with the bike running, if I pull in the clutch, and shift into first to take off, or when I am sitting at a red light holding the clutch, the bike tries to lurch forward, it wants to go, this tells me that the clutch is not disengaging all the way. PLEASE HELP.
