I just ordered my jets today, so hopefully they will be here before the end of the week.

Another quick question, anyone have or know of a picture that depicts each part of the carb that I am going to have to change and adjust?  Which jets, mixture, idle screw etc?

In that picture, is that showing the bottom of the carb with just the bowl off the bottom?

If thats the case, can I do these adjustments without having to take the carb completely off?

Yes.

The bowl screws a re bitch to get off and I recommend changing them to Torx bolts. You can access the bowl without removing the carb, but chances are the screw will strip. OEM screws are crap!

If I remember right I had it out a couple years ago cause I had to completely clean my carb cause I got some dirty gas and which ended up clogging some jets.  So hopefully it should be a problem to get out.

Oh, so can I do the adjustments without pulling the whole carb out?

Yes.

Loosen the carb at the carb boots, twist the carb clockwise, and access the bottom from the left side of the bike.

Up and to the right of the main jet is th pilot jet.

Factory pilot should be a 22.5 if memory serves me correctly.
