Just got back from the 10k service, eventually paid 540 euros for materials and labour. Valves where within specs and there were no other significant points of worry. This gives me mixed feelings because I just paid a huge amount just for someone to say the bike is in good condition but on the other hand I should be glad that there are no issues. PS: They also charged 35 euros just to clear the wrench notification on the dash :P.
It's alot of work just to get in there to check the clearances. I would think add another couple of hundred to adjust if they needed that.
I would expect that the majority of owners would have the same results, and given the difficulty of the job, I hope I am one of them. Unless I get problems I am thinking the 40,000 kms would be a reasonable option. After all, most things in the Workshop Manual can be taken with a pinch of salt. I run my bike in very hot conditions and generally slow traffic conditions too. Long runs are fairly rare and amount to max 500 km at average speeds of around 50 kmph in temperatures of around 35-40c so the oil has to work pretty hard IMHO. For that reason I change my oil and filter at 2500-3000 km it cost me only $20 all in and I feel it is worth it. The bike has a Magnetic Sump Plug as standard, well at least mine does ??
By the way, the dealership said that they dropped the engine which is easier and faster than having to deal with the airbox, fuel tank and swingarm. Maybe someone could try that out, it took them around 4 or 5 hours to check the clearances that is with dropping the engine method.
