Hi, Menace2 and the usual suspects are:
1. Fuel tank empty.
2. Fuel supply valve/petcock turned off.
3. Fouled spark plugs.
4. Engine flooded as a result of overuse of the enricher.
5. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
6. Fuel valve/petcock or filter clogged.
7. Discharged battery, check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
8. Loose or corroded wire connection at the coil, battery or plug between ignition sensor and module.
9. Spark plug cables in bad condition and shorting, cable connections loose, or connected to the wrong cylinders.
10. Ignition timing incorrect due to a faulty ignition coil, ignition module or sensors (MAP, CMP, CKP, O2 and/or BAS).
11. Security alarm needs a reset.

SOURCE: Help with my aprilia AF1 125?

Congratulations. You have just purchased a very high performance 2 stroke 125cc from a very talented Italian manufacturer. A two stroke engine needs 2T oil to be mixed with the fuel before it is fed into the engine. This is a cumbersome job and one has to get the ratio just right. So in order to make the job easier you have two tanks. 1) The regular fuel tank & 2) A small capacity 2T oil tank (made of plastic mostly) which is hidden behind a side panel. In order to give a regular dose of 2T oil there is a tiny oil pump attached to the side of the engine. This oil pump has to be actuated simultaneously when the carb slide is actuated. Hence the banjo. So now you know why the throttle cable splits into 2. One goes to the carburator and other to the oil pump. Good luck and enjoy your bike sensibly.,,,

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.,,,

SOURCE: I want to buy 1990 aprilia af1 it

It has the same engine with Mitto but that engine is more fragile than that of the CBR's.
Don't buy it if you ask me.

  • 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?
Can I get a “very helpful” rating on this answer? Thanks!
