Every engine has one, and we’ll explain how to utilize it in the later sections. They can go past 14,000 RPM in some engines, which is incredible.Information on 2 stroke timing curves. IGNITION TIMING. Combustion of the fuel/air mixture does not happen all at once like an explosion does. It happens as a progressive burning of the fuel, starting from around the spark to the outermost combustion area. ... Retarding the timing will make the power band smoother in the mid-range and give …Constant gas on, brake hard, gas on is normal for a 2 stroke. The power band is exceptionally narrow, and so you have to work hard to keep the engine boiling. The four-stroke is an entirely different beast. It has a far broader and smoother power band, which runs through the mid-range, and up to the dizzy heights of 14,000 RPM. The peak …I would go with a YZ250 because they are so versatile. It doesn't take a lot of money and work to transform what is a great motocross track bike into a serious woods weapon. You will hear some guys say the YZ250 is "overrated" but there is a reason it is arguably the most discussed bike on Thumpertalk. A lot of people own and ride a YZ250. For a bit of a demonstration, try to accelerate when your engine is running at very low rpm and notice the change in acceleration as the engine gets up into normal operating speeds. Two stroke engines will typically have a narrower (smaller) powerband than a four stroke, hence their mention on the linked page.
