2004 RS 125: aprilia rs125 2004 plate, cuts out when warm... wi...

SOURCE: de-restrict an aprilia rs 125

You shouldn't have to restrictions only happen on faster bikes 600cc onwards but if you talking about the inabilty to push your revs to the very max, I wouldn't do this unless you know what you doing, and by you asking this question, you don't know what u doing, this rev restriction is set in place for safety of your engine, rather than restricting speed.,,,

• 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: why does my aprilia rs 125 clutch pressure plate keep breaking?

hey how ya going im a apprentice motorbike mechanic what ive found with these temperamental buckets is that sometimes if you dont have the clutch pushrod on the actual clutch case adjusted properly the activation arm goes past its throw and pushes on the inner race od the bearing and breaks it so get a new cable new pressure plate and adjust properly i adjust it be screwing till i feel the resistance then back of 1/4 turn to 1/2 turn i hope this helps thanks heaps guys.
