It 's always fun to go for your bike dirt faster and stronger. However, it is difficult for many drivers to choose what they want to buy for your bike, because money is tight. If you are a Yamaha WR250F dirt bike, but his own, then you're really lucky, because I'd like a couple of mods that you do so that I can quickly share with others. Oh, and did I mention that they are free! So if you want extra calcium from your motocross almost-but-still-a-bike-path, then you're in the right place. ThisThe changes consist of changing the air-box, exhaust, CDI wire, and to stop the accelerator.
Air-Box Mod
The stock airbox from your WR250F Dirt Bike has an air intake / shield that protects the air filter from water, sand and other debris. Although it is safer on the filter, but no real power, because it blocks the airflow. For this change, just unscrew and remove it from the screen. This mod is more like the YZ250F, because they are not on the screen.If you go in the desert or a dusty track and want to protect the air filter, simply screw into the back of the screen. This is more of a difference to the years 2001 and 2002 models will do, why limit the latest in a battery box air, the air flow.
Discharge
The exhaust deflector on the WR250F is very restrictive, because to be quieter and have a spark arrestor for riding it. The drain hole is very small, a lot of power to remove dirt from your bike. To removethe flap must take ten millimeters lives at the end of the silencer, it stops there. Then just hit the deflector and will immediately gain power. Although this type to make the bike more power, will keep a lot stronger, so that in mind when you are near grumpy people who do not want people to have fun to drive in those days.
CDI gray cable
The gray wire on the window WR250F CD ignition with the floor. The gray wire is that the temporary difference WR250Fthe YZ250F. It delays the time of the second half of the upper end of the number of turns, which makes it a slower lap and narrow. He must have more power at higher revs just to get rid of the gray cable. You can cut or remove and cover with tape.
To get the wire to the seat, tank and masks. Find the CDI, which is a black box (on the right side of the headstock for models '01-'02). There should be two differentGroups of two wires from the CDI. The kill switch is a black wire and black wire with a gray stripe. You want the other group with a black wire and a gray wire. It should be under the frame where the gas tank. Then just unplug the connector and pull the ring of dust. Insert the plug back and tape the wire you just cut to the port. Then just slap the tank shroud and tank back and you're ready to go!
Throttle
Who Wants to Belimited, especially on a dirt bike? I know that I do not know, and is one of the first things I want to do on a WR250F is the removal of the throttle ridiculous that there are limits to 3 / 4 gas. To resolve this problem, you need to go on the right side of the carburetor and the cover of the gas that has a few screws. The inductor is a screw on the underside of the throttle plate, as shown in the figure. To change the length of the stop YZF gas, pull and cut with a saw. TheOriginal size is cut to between 30 and 35mm, and about 25 mm. Reset the throttle lever to stop and that's all.
After you do these mods on the bike as close to a YZF motocross as you can get. There are some changes you can do for your WR250F, but require some special tools and a little money 'more. At the end of the exhaust deflector, and decide that is too strong, where you drive, you can only get to use a waste gas for them, which lowers the decibels, while stillhold more power. Good luck and drive safely!
