It 'always fun to go to your Dirt Bike stronger and faster. But it is difficult to decide for many drivers, what to buy for your bike, because money is tight. If you have a Yamaha WR250F Dirt Bike, even then, you're just lucky, because I want a mod that you can do in stock, to make it faster. Oh yes, and I said, I'm free! So if you want the extra kick from your motocross bike, almost-but-still-a track bike, then you're in the right place.These changes include changing the air box, exhaust, son of the CIS, and stop the valve of the gas.
Air-Box Mod
The stock air-box on your WR250F Dirt Bike is a snorkel / water shield to protect the air filter, sand and other foreign bodies. Although it is safer for the filter is removed use HP because it blocks the flow of air. To change this, simply loosen the screws and remove the screen. This mod is more similar to the screen because YZ250Fhim. If people in the desert or a dusty and we want to protect the air filter, easy to screw back on the screen. It's more of a difference in 2001 and 2002 models do, for the most recent battery box air, which limit the airflow.
Exhaust
The exhaust deflector on the WR250F is very restrictive, because it is silent and have a spark arrester for off-road trail. The mouth is very small, with a lot of energy out of the Dirt Bike. ToRemove the grid, you must exit seven lives mm at the end of the muffler, are still there. Then just slide the diaphragm and you have the power immediately. Even if it'd make the bike more power will be much stronger, so remember, if you travel near grumpy people who do not want people to have fun in those days.
CDI Gray Wire
The gray wire on the WR250F CD ignition box connects to the ground. The gray cable is that the timetable for the WR250F'sdiffer from the YZ250F. Slows down the timetable in the mid to upper end of the range of laps, go slow and small. To get rid of him more power in the range of speeds just above the gray wire. You can cut, or you go out and cover with tape.
For the wire before the siege tank and radiator shrouds. Find the CDI, which is a "black box") (on the right side of the handlebars for the '01-'02 models. There should be twodifferent groups of two by the son of the CIS. The circuit breaker has a black wire and black wire with a gray band. You want the other group with a black thread and a thread of gray. Should be below the frame when the tank. Then just remove the cap and pull the ring of dust. Put the cap back into the group and the son, just assumed the connection. Then just hit the tank, shrouds and back on the gas tank and you're ready to go!
Throttle Stop
Who wantsbe limited, especially on a dirt bike? Do not know, and then one of the first things I did on a WR250F is the elimination of the stop throttle ridiculous that there are limits to 3 / 4 gas. To get rid of what you need on the right side of the carburetor, and shelter from the gas that has a little 'of all the screws. Gas is a screw on the underside of the hard disk and gas, as shown in the figure. To change the length of the gas YZF prevents you from taking and cut with a saw.The original size is between 30 and 35 mm cut, then to about 25 millimeters. Adjust the brake pedal and again that is all.
After these mods the bike is closer to a YZF Motocross Bike, as you can get. There are some other changes that you can do to make your WR250F, but require special tools and a little 'money more. When you consider the exhaust deflector and decided it was too difficult, where you drive, you can only make use of exhaust gas for them, which lowers the decibels, thenstill hold the majority in power. Good luck and bon voyage!
