I don't ride much so my bike has only 13k at the moment. I went to the dealer to get the oil changed because I live in the city and I have no way to clean up the mess and mostly because I needed my lights to be adjusted. Anyway, they said I should get the big 12k service done. They quoted me almost 300€, so I obviously said no. I wonder if there is anything important in there that I should maybe get done individually? They are the official dealer and very expensive, in my opinion, so I would find a cheaper place to get done what actually needs to be done. They mentioned valve adjustment(i think) and checking the spark plugs. I don't know what else though. For 300€ there has to be way more.
The manual lists valve clearance every 42k and everything else is such that if it ain't broken, no need to fix it. The only thing listed is changing the spark plugs every 12k. But man, 12k is nothing. And again, if it works, why fiddle with it...
