    What do you mena with different base map ? Isn't it just a 0 map ? Would you like to share your maps- just top see how you go. I did the following mods: - Number plates form the 10 model - Airbox mod - TwinAir Flow kit - Dr. Dubach full system.. I just leaned it from midrange to top and richened it in the bottom area...

  3. hey guys ... mine does this too .. i've tried al the pilotjets from 40 - 48. The bigger the pilot the better it starts cold BUT .... It won't get alive when stalled ... Any suggestions on a better setup ? Who knows why the 08 one comes with a much much bigger Main Jet than the previous models ? BR //jf

    Oil problem

    Hi all, i'am riding a crf 450 03 most times with the 17' rwheels on. Since a few months i noticed that the ammount of engine oil increases !!! As u know the crf as engin and gearbox oil seperated, Now it's so that i somehow lets oil from the Gearbox side in to the Engine side. When i measure the ammount i loose on gearbox its almost equal to the ammount i gain on the Engine side .. Does someone have an idea ? Its hard to say how much it is .. It somehow depends on the track i race .. on faster tracks its more than on slower ones .. i am getting crazy ! br, //jf
