I have an aprillia leonardo 125 moped and every time it rains or I drive in wet weather, the bike keeps stopping and I have to keep trying to restart it, which can be numerous times and I need to find a solution to this problem as it as dangerous, because the bike can just come to a halt when i am driving in busy traffic and i have to get off and push it off the road and keep trying to start it up again.

put it on a charger and then start it.  pump the gas to prime it.  You'll need to replace the battery because it's shot.  I have a Aprilla 250 and love it.  

SOURCE: how do u change the back tyre on an aprillia

you need to take the wheel out of scoot...this involves taking exhaust off to gain acsess...& undo one of the shocks....& taking mounting plate of to get at wheel..then undo wheel nut..which will have a split pin in it...then when you get back wheel out..you can change the tyre...
