GT125R (carby)

Quick update, and 5th is definately still there. Need to go out and do some more testing, but without the engine running I am able to shift into all 5 gears. What I did notice is that after changing to 4th I was unable to select 5th exactly as it had been when riding. Then, when I rocked the rear wheel with upwards pressure on the selector, it slipped straight in. Seems strange that it wouldn’t go in when riding, as the motion of the back wheel was what allowed it to slip into 5th with the engine off.

I don’t know much about the gearbox setup on bikes, but it seems to me that this is just an adjustment issue. Something seems just a hair out, and if it will actually shift into 5th, then this will rule the pawl spring out, right?

I will have a closer look at the adjustment on the connecting rod and see if this will make any difference, but it seems that something in the gearbox selector assembly is coming to a hard stop between 4th and 5th.
