Try testing the voltage in the battery should be around the 13 volt mark. Remove battery from bike (undo negative lead first) and see if battery will charge. Do not use a car charger it will damage the battery. Use a charger that has an out put of less than 1 amp, if the battery accepts the charge leave it for a few hours. Refit the battery to the bike (connect positive lead first). If this does not work try looking at fuses could be one or more have blown. A few afterthoughts come to mind 1. do you have an engine run/stop switch and is it in the run position. 2. does the clutch lever have to be operated to start the bike. 3 is the bike in neutral.

on the x9500 that uses the same engine there's a reset button to press after a service hidden under a front panel, on some of the other Piaggios it's reset by using bottons on the speedo. so sorry I can't actually tell you on this model, but it will be along those lines.

Check your starter. It sounds like this is the culprit.

Have someone get the error codes from your car's computer with an OBD or OBDII scan tool. That light means you have a problem that needs repair, and the error code will identify what's wrong.

It could be a wheel balance problem, engine misbalance due to poor firing on one or more cylinders or a wheel bearing. Place the bike on a paddock stand to check for wheel balance and wheel bearing errors.

more likely a fuel hose problem.. could be a clogged filter, a pinched hose even a dirty carburetor .. it's not a tight clog it just slows the fuel enough to starve the engine then over time it drips enough fuel into the carb to allow start and run for a short while before clogging again

It sounds as though the mixture is way too rich. Is the choke stuck on or malfunctioning? With is dry spark plug but fuel in the carburetor, try turning the fuel valve and choke off and then with ignition on and holding the throttle at least 1/2 open, kick the engine over several times. If it starts under these conditions then perhaps the float(s) in the float bowel have leaked and are full of gasoline causing the fuel to flow continuously into the throat of the carb then into the engine. It probably is some sort of carb mixture setting, choke or needle valve/float problem.

CHECK THE CABLES THAT GOES TO THE SPARK PLUGS. IT MIGHT BE LOOSE OR BROKEN.

Possible warped/cracked head or cylinder wall.

Time to disassemble the engine again,,, you can see what is causing the problem ... proceed from there...

try some bradex easy start, down inlet.

still think you have a plugged carb passage somewhere maybe an idle air passage, you used carb cleaner and compressed air to blow this carb's jets out?
