I have recently reassembled my D10A engine  as fitted to my D10 SPORTS. 

I found it difficult to test the gears with the engine on the bench. So I waited until it was back in the frame. 

With the engine in the frame and clutch operated,  I can click up once, down into neutral and then what I think is 2nd. But no further clicks for 3rd or 4th. 

I have yet to put oil in the gearbox/engine and the engine is not running during the test.

It is such a long time since I have ridden the bike I can't remember if this is normal with the engine off and bike stationary. 

Let me know if I should wait until the bike is running to check if the gearbox is OK or should I already be worried.

I think  I took good care to ensure the gears were all correctly positioned and didn't disturb the selector parts during disreassembly or reassembly (well apart for the selector shaft which came out and pushed back in). All gear parts only checked for wear and condition. 

I know gears were all OK on the road before I started work on the engine. Although never as positive as I would have liked ( a few false neutrals.)

Have you tried forward pressure on the output sprocket whilst operating the gear lever? I find it helps to nudge the gears in the right direction. Same when riding, taking the slack out of the lever movement helps give a smoother change.

In your case, just push it forward while changing gear - you shouldn't even need to use the clutch.

Hi Colin, if the ears were working "okay" previously then probably nothing too much to worry about. Something's maybe shifted slightly during rebuild and might "jiggle" itself back in position. A couple of new springs on the gear selector might tighten things up for you ?  Right nuisance after all your work..... We've got a new D10A owner in Barrhead now as well to keep you company 🙂

Can’t help but notice that 3rd sentence. You are clicking up once, down into neutral and then what you think is 2nd?  Have you got that right? You did say it was a while since you have ridden it.

It’s down into first then up up up into top.  Opposite to many other British bikes.

Take it into A&E and they`ll slip an endoscope camera through the oil-filler hole to check out the gearbox internals 🙂 Actually a decent one is not that expensive to buy...

Thanks everyone for your advice. I got the bike rolling and the gears are clicking through. Might have helped if I'd remembered that the gears work in reverse of most other bikes. Must be an age thing . . .
