  • Allows full throttle
  • Gets rid of "the bog"
  • Eliminates power robbing emissions
  • Makes needle and fuel screw adjustable
  • Gets better mileage

If you have a new off road motorcycle with emissions controls you are probably frustrated with the low end response or bog that plagues your bike. You have probably noticed that there is no way to adjust for this. This really takes the fun out of riding. Fortunately F2 Racing has developed a kit with the help of 6 time Baja 1000 winner Steve Hengeveld that eliminates the emissions system and gets the power back that was lost along the way. This kit contains EVERYTHING you need. Not only does it restore power, but it makes everything adjustable and easy to work on. These kits have been tested by Hengeveld and have his stamp of approval before being made available to you.

WORTH THE MONEY April 21, 2008
Reviewer: Jurk from North Idaho, United States  
I always liked the wr models from my 250 to 450 but hated how the power was snuffed out. Now with this kit the bike runs like it was meant to.

i got the first one August 29, 2007
Reviewer: Rick Bagley from Bigfork, MT United States  
Hey. let me tell you: if you are riding a stock wr 450 you are missing the boat. i made the initial changes the magazines suggested, but after the power back kit and lots of calls to Dylan, we have this thing figured out. My bike flat out rocks. i am racing the desert 100 in odesa WA this weekend and i expect to easily get the holeshot against the motocross 450's. i highly recommend the power back and dylan will work with you no matter what. Even if it takes 15 phone calls - which it won't now that we have it figured out - even with an after market pipe and a non tuner such as myself. it is a torque monster. hang on and smile.
Thanks dylan
