2 Stroke vs. 4 Stroke Engines
This is becoming a big topic in the riding world. I started out riding when 2 strokes were dominant. Two Strokes are fast when you look at how little the engines cc's are (example the 250cc.)They have great power but only through a relatively small range of high rpms. This is where the problems come into play. If you’re a new rider, its hard to keep the rpms in the small window of good power. Two strokes always keep the riders on there toes. They want to be shifted a lot, the clutch slipped, and the rpms screaming. This can make for a lot of fun. The maintenance on a 2 stroke is pretty basic since they use reeds instead of valves. The only tricky thing about some 2 stroke motors is most of them require the oil to be mixed right in with the fuel. It is very simple to do, just be sure to keep a jug for premixed fuel only. How to premix my fuel.
The 4 stroke is a totally different animal. I had just bought my first Honda 650 4 stroke ATV in 2005. I have to say it took some getting used to. It’s much heavier and wider than I was used to. It doesn’t get up to speed as quickly as the 2 stroke does right at first; however, it runs right by it on the top end. The nice thing about 4 stroke motors is you can be at low rpms and pin the throttle and it gets up and goes. They have a lot of power from low rpms until its time to shift. Four strokes don’t turn as high of rpms as 2 strokes, but they make power over a wider range of rpms. This means you don’t have to work hard to find good power. Basically pick a decent gear and pin it. The down side to 4 strokes is they require more maintenance. The valves need to be adjusted, the spring pressure needs checked, oil filters changed, and valves lapped. These are things anyone with a little mechanical skill can learn to do on there own. It seems like a lot of work, time, and money just to ride, but it's actually pretty cheap to take back to the dealer to have serviced. The 4 stroke is a very reliable machine and is quickly becoming the wave of the future. Years ago you couldn’t find a 4 stroke able to hang with a 2 stroke. Today we see 4 strokes everywhere. They are just easier on the rider, and are always making big power.
