Guys looking for some advice. Took my xt660r (07) out for a ride today after a long lay up. Got the MOT sorted no problems. Noticed problem changing up 2nd to 3rd and to 4th. For awhile I thought it was clutch adjustment as i seemed to be able to bypass the problem by clutchless gear changes. anyway I adjusted the clutch but still there was the problem. It just won't engage on the up shift. If I revved hard its seem to help.

Any ideas guys as to what's wrong with my beloved XT??

Cheers
