This is a severely abused machine greatand every time I remove any part to inspect it...almost every part needs repair or replacement. For example...the O Ring on the Intake manifold was shrunken and dry rotted providing no sealing benefits whatsoever on the cylinder head. No bent valves, no broken timing chain; but severely worn and partially damaged chain guides along with a damaged drive belt were found on it today. The O Ring on the Intake manifold was suspect for quite some time. This is a 2014 scoot with many miles on it.

Age doesn't hurt as long as preventative maintenance is followed. I have a 2006 & it runs great!
