I hav recently imported 2x 1980s vespas a 1985 px150e and a 1981 p150s.
I got them all signed off by the mechanic locally and looked good to go.
Both bikes when riding home, had the rear wheel completely seize and I came to a large skidding stop.
Scared the shit out of me!
They both started again and seemed fine and I am now trying to get to the bottom of why this happened.
The fact it happened to both bikes makes me think maybe its a fuel/oil mix issue as thats the only thing that was done by the mechanic to both bikes and seems like one hell of a coincidence otherwise.
The bikes aren't idling particularly smoothly and checking the the spark plugs they look quite oily.
The bikes both ride fine now but I am hesitant to to go too far incase it happens again.
Any Help would be greatly appreciated.
I am a complete noob sop please be gentle
