a piaggio model ciao + - 1962 mobilette or scooter. the mix for the gas RATIO i do not have it on the scooter thanks please send info to vnmon@hotmail.com thank you 50-1 ratio just like a weed eater The Vespa /Piaggio mopeds use a 2% gas/oil mix. Find a Ratio Rite mixing cup at a shop that sells dirt bikes and use the column marked "50:1" ratio. Being an older bike it may not hurt to add a bit extra oil, say 35 -40 to 1. This will keep all parts well lubricated but it will blow more smoke and will drop performance. This can be recouped with an addative/ octane booster. |
