OK, thanks.
Wow, one quart of quality 80w90 <$10 and if info that S8150 takes 200ml per change is accurate then almost 5 changes. This machine looks like it is gonna cost me very little to operate and maintain 
Can you tell me the milage intervals between engine oil and gear oil changes? I am fully confident that I will be able to do liquids at home.
How often do valves need adjustment? What other maintenance will I have to have dealer perform?
Per the manual. Oil & final drive change @ 300km/180mi. Oil change @ 1000km/600mi. oil change @ 3000km/1800mi. Oil & final drive @ 5000km/3000mi. After that, oil change every 2000km/1200mi. Final drive every 5000km/3000mi. Clean the oil screen every other oil change.
Valve adjustments every 4000km/2400mi
Spark plug clean @2000km, replace @ 5000km
Air cleaner - clean @2000km, replace @ 5000km ( I doubt this is necessary - see how dirty it is)
drive belt - inspect @ 7000km
there's some other little stuff like inspect for loose bolts (I have found some loose bolts), clutch lever freeplay ( yeah right - clutch lever?), check tire pressure, lube brake cable). I plan on doing all my own maintenence but I am considering having the dealer do the first valve adjustment & look it over for warrantee purposes.
If you do your own valve adjustments, you will be able to see how much the clearances change and probably do the adjustment less often. I have found this to be the case on my motorcycles.
