it means that you're running very lean. as a short term fix you can turn out your pilot screw underneath a 1/2 at a time.

post your jetting here and we'll get you a proper set up.

the needle is **** get rid of it asap.

go to an EMM for sea level or EMN for 2-3,000' plus. BTW because i don't ride at those heights i can only go off of your feedback ok!!!

put either needle in on clip 4 and put in a 160MJ.

if you want to go the whole hog with the MAJ change and the PC all leaned off like mine, well, it's all in my signiture to read etc so good luck with that.
