The warning light and EFI will disappear once you fit power valve :)

I've got 2008 Aprilia RS125 and CDI I derestricted first.. I had warning light on until I fitted power valve.. No warning light now.

• Start with a new spark plug. Now do you see spark? If not, check the side stand kill switch. It kills the engine so that you don’t start out with the side stand down. If broken or out of adjustment, it would kill the spark. Check for a broken wire at the side stand switch and coupler. Try moving the kill switch by hand. If that doesn’t work then wire a jumper around the switch to bypass it.
• Check the fuses. How good is the battery? Try a jump start from your car battery. Is the handlebar kill switch on?
• Check the operation of the ignition switch and all kill switches with a volt ohmmeter. Check the wiring harness. Did a wire come unplugged? Are all wires clean and with solid connections? Any abraded or pinched wires? Is the bike in neutral and the neutral light is lit up? If no neutral light, check the neutral switch and neutral switch wire on center casing. If still no spark, get CDI system and coils checked at the dealers shop.
• Are the fuses good?

SOURCE: does a aprilia rs 125 have a thermostat

yes buddy as the rs125 dont have fans on the radiators so the faster you go the more are passes through the radiator to cool it down dont worry abour it buddy there built for this or if your not happ install a fan your self also just make sure you have coolant in there
