So I just bought the scooter about a month ago and I took it in for the first 1000 km service. I noticed in the manual it says you should adjust the valve clearance for this service. I don't think the dealer did this. They never opened up the engine. I should have not paid them the $150 to simply check stuff and change the oil what a rip-off. Does anyone know what the valve clearence is suppose to be on the People S150 I want to just do it myself. Thanks for the help.
