05 WRF450 Fuel Screw Question
Posted March 15, 2005 - 07:18 AM
Long time lurker, first time poster. I've gotten lots of info from the forum, but now I need some advice.
Got an 05 WRF450 today, and it seems really lean off idle. I know it is brand new and all, but it won't idle without the choke (regardless of engine temp) and generally runs much better from closed to part throttle opening with the choke on. With the choke off, big flat spot, then bam. Seems super lean. I am at sea level, and it was about 65deg here today. It also pops and spits a lot during decel.
Will adjusting the 'fuel screw' help? If so, where is it and is it plugged/covered on 05 models? I bought it in Dubai, UAE and am riding it here in Saudi Arabia, so I don't know if it is US or international spec. It has the AIR system, so I'm assuming it is US spec. I have pretty extensive experience with street bikes, but haven't ridden a dirt bike since my '86 CR250. Are these things jetted pretty well out of the box?
Any helpful input appreciated.

I realize that a JD kit might not be easy to get in the Saudia Arabia. The fuel screw needs to be opened up. I used a wood screw to pull the plug out of the carb body. The screw is underneath the plug. A hole is already drilled in the plug so its easy to get out. I use 1-1/4 turn out.
