Jetting Question

2 posts in this topic

I see that all the historical info. regarding jetting is no longer available? Not sure what happened?

At any rate I'm in the process of setting up the carb on my new 2009 WR450;

I have have the JD kit and it states to use the 168 main; Others have used the 165 main and have been successful. Any opinions on this; I'm located in IL and elevation is about 700 ft.

I plan on using the red needle with the clip in the 4th groove. Also have the PMB insert in the exhaust and plan on removing the plug from the top of the air-box and disconnecting the grey wire.

I was kinda thinking that if I go with the 165 main that my jetting would also be good for Moab; A place I like to visit once a year or so :thumbsup:
