I am daily riding my 77 400F and I am having trouble getting 3rd gear to engage sometimes. Every once in awhile it just seems "locked put" until I try again. The second time usually gets it. I believe the clutch is engaging fully, and all the other gears seem fine, except that 6th will pop out into some sort of "neutral" position if not rigorously engaged. Any ideas would be appreciated. The bike has 10 700 miles on the clock.
