SOURCE: Aprilia RS125 Help

Ive just bought a 2000 model RS 125 but my knowledge of bikes is pretty limited :/ The bike was running fine for a week with no problems at all but then the electric start doesnt want to work. I went through the manual and tried a couple of things (recharged the battery checked fuses cleaned spark plug etc) After I did this I still didnt have any luck but the electric start sounded abit more promising. I gave it another couple of goes and it started but when I let the throttle off the engine died and Im back to square 1. Anyone have any ideas about what could be the problem? I was talking to a friend and he said that I need to make sure that there is power going to the motor. He mentioned using a voltmeter to see if there was power going into it. He said that if there was no power then it would need a new electric start but if there was then I would need something else but I cant think what? Does this sound right to anyone?ou'll be able to tell if the ignition system is okay if there's a spark at the plug against the head with it removed when you kick it over (is there a kickstart lever on the bike?)/spin it over with the electric start. You could try bump starting it to see whether its just the electric starter motor or the ignition system itself that's the problem. If you do have a good spark then the bike should start with a bump push start/off the kicker (does it have one?)then you'll know whether the starter is the problem. My bike's kick-start only though so I'm no expert on starting Aprilia RS125's...Good luck. Don't waste money on new parts until you're sure of the problem though.,,,

SOURCE: Fuel tap

The fuel tap is located on the left hand side of the tank, just about where your left knee is. Turn fully anti-clockwise is off, from there turn half way, pointing up is on, and fully turned clockwise is fuel reserve. not much in the reserve but enough to get home or petrol station.

they can be a bit touchy on gears start the bike in first holding the clutch down so that you dont jolt forward lol and try and put it in nutaral but only move the gear leaver a slight bit upwards if no luck then put it into second and try the other way by putting it down only slightly. if nothing then you could do what i had to do and ajust the gear leaver nut by taking the leaver of and moving it anti clockwise a few notches and make sure it gose back on the teeth or you risk weering them down give that a shot. if nothing let me know

SOURCE: How do I reset service spaner icon on my aprilia

hi, if you hold in the small button on your left handle and turn the key in the bike to turn it on, do this about four times and be sure to hold the button for 10 sec each time.

i had to do this on my rs 125 and it works!!!!!!
