A clogged gas cap engine hole can cause this.

If ok, change the fuel filter(s).

A clogged filter will allow a little gas through but can keep up with demand.

OK< can you provide more details? Does it turn over? Does it fire at all? Do you know if you have a spark? Do you know if fuel is getting through? Has it run properly recently? To run, a motor needs fuel, air and spark Inspect all fuel lines and wires. Pull the sparkplug and see if it is burnt/wet/corroded

Look in the owners manual

It's not the new switch, it's the new keys that have to be programmed. The keys have uniquely coded chips in them, when you turn on the ECU uses the antenna that is by the ignition switch to look for a code that it recognises, you need to introduce the new key codes to the ECU. This is what the manual says: In case of installation of a new ignition switch the procedure is as follows: Turn ON using new key The dashboard will not recognise the key and will ask for the customer code: insert the customer code. It is 00000 when supplied. It can be changed to any numeric five digit number. Now you can enter: MENU, DIAGNOSIS (insert the service code 25973), Then select MODIFY KEYS and implement the procedure. If you are not sure about the mode switch, this is what you do: Use handlebar "mode" switch (left / right) to select "Menu" option on the screen, then press mode switch in to enter. Use handlebar "mode" switch to select "Diagnosis", press to enter. Use handlebar "mode" switch to enter the workshop code (25973). When you have selected the digit you want then press in and it will move to the next digit etc. You can't screw anything up, if you do it wrong go back or turn off and start again.

Most likely cause is a broken or bad earth on the dim light (power then has to go through 3 filaments in series to get to the earth on the good light).

Check brake pads first

sorry running rich is not a plug burning problem running too lean is so check your fuel pressures, injector , air inlet (filter)

The coolant system on any engine, including bikes and scooters, does not use just water. You will need a coolant mixture which you dilute with water. There are several types of coolant mix so it would be a good idea to ask an Aprilia specialist exactly which type of coolant mix to use.

Check the alternator output it should be about 14.2 volts at about 1500 RPM

-If you can access to. Good luck Mai

It is pressed on the tapered shaft, you need a tool called a gear puller.

First of all, is there fuel in the tank? is it reaching the engine,have you a spark at the ignition plug?
