I realize 2 strokes have "twice" the power because they get twice the combustion per revolution, but why is the peak/power band so narrow, then it drops off compared to a smooth, even 4 stroke It isn't (well, not nearly so much) with a 2-stroke. Turning it to the left lowers your slide height and your idle. Going back to the engines, a car 2-stroke engine performs two power strokes per combustion revolution. other than that its all hardware changes like pipe, carb boring, milling the head, cylinder porting. 5 mm is a big power loss to them,so you may have increased low speed power,but definitely lost high rpm power,which most chainsaws run at. The correct oil-to-fuel ratio ensures optimal performance and longevity of. I set it to the stock position (being 1 turn clockwise).

The powerband generally kicks in at higher RPMs (when the bike is "revved high") compared to a 4. checked carb all jets clean and OEM reed valve is fine. The right blend ensures that your engine runs smoothly and efficientl. But more strokes mean less power density. TWO-STROKE PRINCIPLES Although a two-stroke engine has less moving parts than a four-stroke engine, a two-stroke is a complex engine because it relies on gas dynamics.
