there are a few basic rules how to use a 125 cc 2-stroke sport bike with high power. first, most important is, always, before riding, WARM IT UP! it has to have at least 50-55 degrees ceslius before accelerating at full power! then, use the best 2-stroke oil you can buy! I use Castrol TTS, well, Motul is also very good, but very very VERY expencive!
when you put a new piston and cylinder in, you have to prepare the engine for the running at full power. it takes around 300-500 km, and you have to ride with RAVE valve CLOSED!! if you made the engine work, sat on the bike, and accelerated to top speed as soon as possible, that was the worst thing you could do! you should just start the engine, ant let it run 10-15 minutes idling (standgas), then go on a giro of easy riding, and next few hundrets kilometers ride without accelerating at full power!
