Question about 2000 Aprilia RX 125
Aprilia RX 50 will start fine but only rev to 5000 rpm and not 10000.
Carb spotless clean tank flushed through new plug. Any thoughts Could it be the main seals
Hi Bobyounggolf, and the usual suspects are:
1. Faulty crankshaft seals, do a visual inspection and pressure test.
2. Power valve failure.
3. Faulty high output coils or CDI
4. Float level too low, restricted main jet, fuel tank not venting.
5. Restricted exhaust port or clogged expansion chamber. I am sorry you can't find the first and best tool you ever bought for your Aprilia but despair not for a mere $10 you can download another one.

Hi and welcome to FixYa,
Jet size would depend which carb is installed, a Dellorto 34mm?
Initially, check the sparkplug tip colors. If very light brown to almost whitish, then lean mix; too much air, too little gas. Try raising the needle if if has notches and moving the e-clip. If fixed, use small thin washers. The basic idea is to make the needle rise early on throttle movement.
If an aftermarket open breather air filter is installed, then it would be causing the lean mix, too much air. Restrict the filter by adding temporarily upholstery foam to experiment at which thickness the flatspot would disappear.
Good luck and thank you for asking FixYa. Happy Holidays.
