So the gear lever moves up/down as normal but doesn't seem to "catch"?
That sounds like it could be wear on or damage to the external gear selector mechanism but it seems a very low mileage for it to happen. Happened on my GPZ (same motor in that respect) but not until it had done over 60k miles.
So. First off check the clutch adjustment and also ensure you are allowing the gear lever to fully return after selecting each gear. Your toe should come fully off the lever. Often a problem when people buy new boots.
Failing that, I'd be looking at the primary gearshift which consists of two metal "hooks" which grip and rotate the selector drum when you move the lever. One hook pulls one way, the the the other way and they are joined together by a couple of small springs that make them engage in the slot on the selector drum.
The points on the hooks can be worm round so they don't catch properly or a spring can be broken so they pop out.
On the plus side, you can get at it without either dismantling the whole engine or taking the engine out of the frame. If anyone twells you this is the case, they don't know what they're talking about.
It's located under a seperate cover underneath the front sprocket. If you lean the bike over top the right, you don't even need to drain the oil. You do need a new paper gasket for the cover.
If it was me, I'd be whipping off the cover and inspecting it. You sometimes get away with simply filing the (surprisingly flimsy) hook back to a point or replacing the spring. You might need to replace the whole selector mechanism. The mechanism CAN be removed and replaced with the engine in the frame, I know because I've done it but it takes some jiggling about.
