Question about Aprilia RX 125 Motorcycles
Hi Johnj_jackso, you may have squeaked your top end this is commonly known as "HEAT SEIZE" the piston heats up expands and becomes extremely tight in the cylinder bore and usually occurs mainly on 2 cycle engines right after a fresh top end rebuild, but it can also happen to brand new motorcycles, but these are rare instances due to better quality control and education. The usual suspects are:
1. Improper oil/fuel mixture ratio.
2. Faulty or improperly adjusted oil pump and or cable.
3. Among the causes of lack of cylinder oil is clogging of lubricator by dirt or waste, obstruction in oil pipes, leaky check valves, leaky pump packing, broken oil pipe, oil too cold to feed, lack of oil in the crank case.
4. Wrong type of oil used in mixture or pump.
5. Failure to follow proper break in procedures.
