There are a lot of high quality picture sequences covering everything from removing a carb to setting valve clearances.
Everything I have looked at so far covers trhe Raid and white Open Enduro models. It may be that the blue TTRs were not sold in Russia?
There is a sequence of colour pics which will let you determine exactly which model TTR you have.
Well worth a browse and very well done GreyWulf - an excellent website
