So a Honda scooter SH150i 2010 22 000 K has shown up where I live for sale. Guy said he got no bills to show anything ever been done to it. Seemed clueless about the Everything do with service and more then likely just never did anything. He s asking 2600 and I m thinking abused like that needing a major service it's worth 1900 . Am I in the ball park? Belt has to be change , valves checked out etc. thanks again .
