Question about 2000 Aprilia RS 125

I have a Aprilia rs 125 2008,done 4000ks. It blows too much smoke

I have a Aprilia rs 125 2008,done 4000ks. It blows lots of smoke when in the power band. Have tried different synthetic oils. Seemed to blow more smoke when I blocked off the SAS. Would like to know how to adjust oil pump so less oil is pumped. It is de-restricted. Runs fine with perhaps a very slight pause midway through the power band?? Not sure what could be causing this? Maybe too much oil ??

Maybe rings are you losing coolant check the spark plug if it comes out with oil or too wet this means your oil pump is pulling to much in get back to me budd

The oil pump has a mark on it that lines up with another mark on the part of the pump that the cable is attached to. Adjust the cable where it goes into the rubber block, so that the two marks line up when the throttle is in the idle position. This seems to have worked on my 08 RS.

Cutting out n blowing white smoke

Hi there!!! White smoke coming out from the exhaust means that your block is damaged and you need to replace it together with the piston. It has loose compression.

Hope you'll be able to fix it!
