Thanks guys, an update from me. I'm headed back to the UK to recover and get my surgery double checked. I've left my bike with a mechanic here, and will come back to finish the trip once able!
I did find a good Almaty mechanic: MCC Motors Almaty. mcc-motors.kz, mcc-motors.com. 8 701 551 4898, 8 707 224 5224
Some friends of friends of mine live in Almaty, and it turns out they ride real bikes: DRZ650 etc and thats where they said was the best place in the city to get it serviced.
I saw how they treated my bike, and they seem to know what they are doing: fixing bent rims, they carry good oils and basic spares, they can do basic metal fabrication (redoing bolts etc).
Walter - worth adding as a way point.
I'm still trying to diagnose what caused my falls, but im sure its something in/around the steering column.
