Hi all. I was riding back from a 6 mile journey on my 2010 K1300S and noticed that my clutch was slipping badly in 4th to 6th. Since then, pulling off in first is a very slow process and the clutch slips so badly that I can't really get the bike to move above 60mph as the revs just fly high without engagement. It's worse when warm, when it's cold I can just about use it in first to third gear without slippage but it's still unusable in 4th to 6th. I have changed the clutch mineral oil and have done a full oil change (including filter) using Motul 7100 and it is exactly the same. No difference in the awful clutch slippage.
Now, before I buy the Barnet clutch pack and get elbow deep, could it be anything else?
Thanks in advance for your help!
