SR125 cylinder and piston.
Hi, anyone know where I can get a replacement cylinder and piston for my sr125.
This is my first engine rebuild I brought a bike where the timing chain had come off I've replaced the valves and rebuild the engine (no damage to the piston). When I done a compression test on the bench it was showing 75 and not the recomend 114+ I put a bit of oil in the chamber and done the compression test again and it shows 125 which means it's the barrel and rings, correct?
There wasnt any oil in the engine when I turned her over will that change the amount of compression ?
