accelerating

Hi all just got my 2001 Mille with 10000 miles on the clock took her out today and noticed the clutch was slipping when accelerating hard even at 145 in sixth gear do I need to change the clutch or is there something I can do to solve the problem

Hi guys from new member, Bought by 2002 Mille the other day and have noticed when accelerating from around 2000 revs in 3rd gear there is a rattle / vibration. It happens in that gear only and not in neutral ?? Wondering if its just the belly pan / chain or somit else vibrating at that...

The bike was fine before I stored it during the winter months. Did an oil & filter change before the winter. Now when going through the gears I'm unable to select 3rd without easing off the throttle first/reducidng the rpm. Any ideas what might be wrong?
