If the clutch is operating fine as well as the shift mechanism, it's either a bearing or a internally cracked case that's allowing the bearing to move. First gear is actuated on the rear transmission shaft that Is common to the drive sprocket on the left side of the bike, and an idler gear that engages the kick start lever to the clutch basket. This is located under the right engine case cover. Remove the chain and sprocket and check the shaft to see if it will move up and down in the bearing. If that's solid, remove the right side cover and check the case and bearing under the idler gear. I have had Yamaha cases crack at that bearing area and cause that same problem. Good luck!

dear mr T-handle, I check out the engine by taking the clurchcover off and what did we find at the bottom of the case......? a valve adjuster...the screw which you turn when adjusting the valves....at the bottom of my case.....so we quickly opened the valvecovers but all seemed well up there....
that little thing was precisely under some shiftter so when I pressed down the lever it could not go down because of the little piece of metal.It was undamaged so we guess it has been there for some time....I really have no idea. But the problem is fixed and ready to roll again!! Thanks very much for your help and advice!!
