wr450f '04 Hesitation then pop?
Posted December 27, 2003 - 08:39 PM
I just did all the mods today, gray wire, throttle stop, JD blue #4, 170 main jet, fuel screw 1.75 turns, air box lid removed, gty-r exhaust insert, 500ft, 55-70deg. The bike feels like it pulls twice as hard since the mods, but the only thing that concerns me is the very bottom like I said before. I also took out the exhaust insert completely and found that it did the same thing. Is there something that I may have forgotten and how can I get rid of this bottom end problem?

I've been reading on the acc. pump adjustments and will start there. It wants to die after the hesitation, and that soundslike the acc. pump adjustments I was reading up on.
It’s amazing how the mods I’ve done so far have given the bike so much more power. I didn’t notice any change having the GYT-R insert in the exhaust or the exhaust open, only louder, so I’m leaving it in for now.
I thought the red needle was for higher elevations.

I ended up adjusted the acc. pump screw 1 clock-wise turn, fuel screw to 2turns and increased the idle slightly. The snap off the bottom was better, it didn’t want to die, and the power is awesome…power wheelies in all gears. I’m going to play around with the red needle next weekend.
Would you run all those needle positions with the same jetting, if I stayed at around 500ft?
