I don't really understand this Slabo. Are we miscommunicating, I can be a bit thick at times!? Anything that comes off the wheel like sprocket or disc has to pass over the axle so it needs removal unless, like chain, it breaks apart? Even that is easier with the bike up. But it is simple enough. Believe me, if I can do it you can or a Chinese mechanic can. I am actually scared of machanical work since I rewired the twelve-volt doorbell to the mains power at age nine and set light to the hall way requiring a fire engine. I sort of look at machinery of all kinds and my mind goes two dimensional and shudders.

The stand concerns? It is a heavy bike for me as I have a few discs gone and can't stand or walk very well even on a good day - but I get a milk crate and sort of wiggle it on then lean, lift and push bike into a stable, solid working position. There is some weight to lift but I manage and have used a car jack to lift it before but that was more chancy. I will get a simple lever or hydraulic stand one day when I see one on special. I have done this a few times with no disasters, get it into the right place under engine and nothing is trapped.

The rear shaft if that is the one you mean, undoes with a bit of leverage from a solid shifter while on the ground, and in fact I had enough resistance when tyre gripped between my legs, wheel off the ground, to apply the rear axle torque (about 70 ftlbs). I can't understand why any equipped mechanic, even in China, wouldn't have the right stand, either leverage type or hydraulic, and wouldn't have the basic tools? Certainly should have a crate or something out the back somewhere! The front sprocket shaft is a well known problem on many bikes but doesn't need removal for any chain, sprocket or rear wheel work.

Good luck with travelling and settling back quickly. And good luck with finding the faults. Usually it is something simple (and obvious in hindsight). Most testing is just the boring and time consuming logic of isolation. Lets hope you are (in this case) as stupid as me and it is the kill switch (which my brain keeps seeing as 'off' when i look at it, even with full mental capacity ...) Of course I move switch the wrong way which means no start. I do it all the time and still get it wrong! same with the choke, i had to paint a blob on the bar to remind me as many times my brain fades and it looks all wrong! Then when I do get it started I ride away from the store in embarrassment and forget to turn on the fuel so I get right into the middle of the long, leaning, sweeping bend up the road over the tight stone railway bridge six inches from the wall, and engine dies again, usually with a few cars close up behind me because it is my village and I stick to speed limit when no-one else does. I am getting on, and did lots of dope when a kid, whats your excuse?
