I have had a lot of experience in this bike, the parts are really hard to get hold of from experience. this did happen to me but mine had a 65 bore kit on it and it turned out to be the bearings. there is not much that can stop a two-stroke bike reving up like that as the mechanics inside are very straight forward. a good tell tale is to check the inside of your sump plug, if there are filings on it as it is magnetic, this is more than probably the bearings and will need rebuilding. really sorry if this is nto the answer you are looking for.

I got smoke from my aprilia rs 125 05


Seems like it has a bad gasket in the engine.
The engine may have damage if it smokes.
Is the smoke white or blue?

Engine wont accelerate and coughs when trys to get to high revs


Hi Odoggg, 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.
