Yes its getting too much petrol , you will have to check the float pin, better to clean the carb.

09 tuono wont start asks for user code

Hi, John and the usual suspects are:
1. Fuel tank empty.
2. Fuel supply valve/petcock turned off.
3. Fouled spark plugs.
4. Engine flooded as a result of overuse of the enricher.
5. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
6. Fuel valve/petcock or filter clogged.
7. Discharged battery, check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
8. Loose or corroded wire connection at the coil, battery or plug between ignition sensor and module.
9. Spark plug cables in bad condition and shorting, cable connections loose, or connected to the wrong cylinders.
10. Ignition timing incorrect due to a faulty ignition coil, ignition module or sensors (MAP, CMP, CKP, O2 and/or BAS).
11. Security alarm needs a reset.

My aprilia 125 moped will not start, there is a spark at the plug, stinks of flooded fuel, it's soaking the plug when kicked over, what's problem?

Sounds like the engine is flooded with gas.Turn the fuel off if you can.Remove the spark plug and move the wire away from the spark plug hole.Now turn the engine over like your trying to start it.See if gas comes out spark plug hole if yes engine is flooded.If it is flood that bad your exhaust will have fuel in it also.You should get a new spark plug before trying to start it again.If gas does not come out the plug hole.Install the new plug and try starting it with the fuel off.Hope this helps.

Aprilia habana cutting out and starting problems

Did you clean the pilot & main jets in the carb & set the float height to standard? There is also an over flow in the carb which should stop fuel flooding into the air filter - did you check?
Make sure there are no splits in the fuel pipes & the smaller vacuum pipe that goes from the side of the auto fuel tap, also check pipes connect well
By your description it sounds like the carb is filling very slowly, 1 bowlful would get you around 2 miles & then plug would be dry when trying to start it, leaving it overnight the carb would fill up & flood air filter due to a leaky fuel tap

Ride safe
Please mark this as very helpful (if it has been!!)

My aprilia tuno125 wont start . all electricks seem to be working. but the starter motor relay is clicking wen i press ignition

Check your battery, it has power, but not enough to engage the starter
to turn. If the battery is good, once you put a load tester on it, it could be your starter solenoid. Good luck.
