Hi and welcome!  The problem is more likely to be the clutch than the gearbox. This problem is quite common and most people who are familiar with A10's will try to engage neutral as you are coming to rest, not actually when you have stopped. The A10 clutch is a bit crude, particularly the 6-spring, and whilst the 4-spring is much better it is still far from perfect. You need to spend quite a bit of time with the primary cover off, making sure that the plates lift off evenly and you need to have the minimum of slack/wear throughout the clutch operating mechanism from lever to the pressure plate to make sure you have maximum lift. A further problem is the design of the levers on A10's which have a short distance between the pivot and cable nipple; this gives good leverage but poor travel. Fitting non-standard levers gives additional travel. At this stage I would concentrate on the clutch plates and general efficiency of the lifting mechanism. It is worth checking that the lever on top of the gearbox is in its most efficient position, i.e. passing through a right angle as it travels, or as close to that as you can get. Good luck.

G'day Bulgaria,  *welcome*. I think your the first from that corner of the globe.
As beezermacc said. Do a search, theres lots of topics on setting the clutch up right.
Cheers

Welcome, a history and some pictures in "Bikes, Pictures & Members" ?

Id' say start with a full clutch check & function\parts inspection + fine adjustment.

 phew, must've been exhausting... *smile*...not being a smartarse(now), but I think the word you mean is "excellent"....
 I think those screws are about 1,3/8" -1,1/2" can check in a few hours....?

G'day Bulgaria.
The screws and studs for the gearbox cover.
1 of 67-1705 = 1/4" x 1 3/8" BSW 20tpi thread
2 of 65-3061 = 1/4" x 1 7/8" BSW 20tpi thread
4 of 67-3023 = 5/15" studs 3 3/8" long BSW 20tpi thread on one end, CEI (cycle) 26tpi thread on the other end.
Most threads into Aluminum are BSW and most nuts & bolts are CEI (cycle) 26 or 20tpi.

 Well Musky's onto it, but maybe not all boxes are the same. ... I measured mine and some in a spare box. ...I was only concerned with the two front ones that you're missing, yes 1,3/8" will be sufficient for the single rear one , but (on mine at least) the front two only need to be 1,1/2", any longer sticks out the back....And with unthreaded shank of 28mm (1.1"max)...

 That was based on the spare box having what appear to be original cheese head screws...@ 1,7/8" long. (I changed the bit in brackets)
 Modern Socket caps screws should be ok though, (usually) having 1" of thread, but I'm sure you can work that out, just wanted to make you aware of that so that it still doesn't leak
