Clutch problem?? Recently my 2008 Harley fatboy while riding at 65-75 mph in 6th gear will loose contact/grip with the clutch.. it will rev without being engaged... I have to downshift to 5th to re-engage then I can up shift and it will continue fine... it is not a regular occurance has done it a couple of times... clutches and plate are in great shape like new... cable is brand new.. oils are changed and fine.. any ideas???

Sounds like the clutch release is not seating smoothly and fully. Operate the release very slowly (preferably out of gear while static or can you put it in 6th while its off? and see if there's any stiction in the clutch release mechanism.Maybe the clearance changes in 6th gear but i cant see why it should.

It could be. How are you adjusting the clutch rod in the primary? Loosen the jam nut and screw in till it bottoms out,then loosen one full turn and lock the jam nut. Then you'll need to adjust your clutch cable. Make sure that you don't take all of the slack out of the cable. There should be room enough between the clutch lever and clutch perch to fit a nickel between the two when it is adjusted correctly. If the clutch lever has no "slop or play" in it,then the cable is too tight.
