dirtbiking
Dirtbikes come in many different years, models and makes. The four main dirtbike producers are Honda, Suzuki, Yamaha, and Kawasaki. I own a Honda. The models of dirtbikes constantly change with the years as they continue to get better and better. My bike is a 2004 crf250x. The 2004 is the year of the model, and the crf250x is the model and the 250 stands for a 250cc engine. Dirtbikes have many different parts. There is the clutch which most dirtbikes have. Most bikes have clutches except for small dirtbikes like 50cc engines and such. The clutch is used for switching gears and is often difficult for beginners to learn to use. Most people who haven't used one struggle with it. Basically a dirtbikes engine is a carburator, a piston and a gear box. Thats basically it to a simple dirtbike engine. They are obviously more complicated and have more parts. They way the bike works is pretty easy to understand. First gas is brought into the carburator from the gas tank where it mixes with air from the airbox. Then the gas moves into the piston chamber where it is ignited by the spark plug. The force of the explosion pushes the piston head downward turning the crankshaft. This causes the gears to move and it turns a samll sprocket on the outside of the dirbike which is attached to a chain. On the other end of the chain is a larger sprocket attached to the rear wheel. The small sprocket turns, moving the chain which moves the large sprocket causing the tiures to move and therfore the bike moves. The throttle, which controls the flow of gas to the carburator is on the handlebars. Obviously the more gas going in the larger the explosions and more explosions means the piston goes faster and the gears and sprockets too so therefore the bike goes faster. Dirtbikes are most often started with kickstarts. They are sort of shaped like an L. Basically what it does is cause the spark plug to spark trying to igniote the gas. The way a dirbike is set up is with the gas tank up on top of the bike. The seat is right behind it and behind that is the rear fender. In front of the gas tank are the forkswith shocks with handle bars on top. On the bottom is the wheel with the front fender hovering over the front wheel. The dirtbike frame is under the gastank and seat and house all the engine parts like the carburator,piston and gearbox. These are at the front of the frame under the gas tank. Then the airbox is connected to the carburator and is under the seat. There is an exhaust pipe coming out of the front of the engine and it runs down to the end of the dirtbike and ends under the rear fender. Under that is the rear tire which is attached to a large arm with shocks on it. There is a chain running from the rear tire's left side running to mid-way through the bike to the small sprocket on the gear box. Larger bikes have coolant and ferrings on the sides of their gas tanks if they are not air-cooled. Mostly smaller bikes are air-cooled. There are front and rear brakes as well and a gear shifter too. There are many small parts of a dirbike but those are mainly the essentials. To ride a dirbike you have to get good with the clutch. What you do is kick over the bike when it is in neutral. neutral is typically located between first and second gear. The gear shifter is located by your left foot. Started off in neutral the gear shifting would be one down and four or five up usually. It depends on the bike but thats pretty much standard. So the bike is running in neutral so what you need to do is pull in the clutch, downshift into first gear and slowly let out the clutch. Now while letting it out just give it a little gas by twisting the throttle a little bit. Now what happens to most beginners is they either let out the clutch too fast and not enought gas and they stall the bike, too fast clutch and too much gas and they flip the bike or too much gas while letting the clutch out and they panic and lose control. It happens all the time. People panic and lose control causing it to flip or crash. Riding a dirbike requires the user to have to know how to use the clutch well. Unless you are riding circles in an open field you will need to shift a lot like coming to a stop or taking corners and whatnot. Shifting gears does get easier once your moving because you can let out the clutch much faster. You can even power shift which is shifting without the clutch. It is not highly recommended though because it isn't good for your gears and whatnot. Also while riding a helmet would probably a decent idea. Whether you aint good at riding or you are, wiping out don't take much. Even if you are better at riding, usually the better you get the crazier you get. I can't count the number of times that i have smoked my head off the ground while wearing a helmet doing stupid stuff.
