THE DIRECTIONS FOR MY YOSH SAID NOTHING ABOUT WHERE THE NEEDLE SHOULD BE SET. HAS ANYONE EVEN CHANGED WHERE THEIR NEEDLE IS AT? HOW COULD IT NOT BE LEAN AFTER ADDING SO MUCH MORE AIR? ALSO, I DID NOT CUT THE HOLES IN MY LID AND MY HEADER PIPE IS BLUE TO PURPLE, COULD THIS INDICATE THAT I AM LEAN AND CUTTING THE HOLES WOULD ONLY REQUIRE LARGER MAINS. PLEASE HELP ME, I AM CONFUSED. I LIVE IN SCOTTSDALE , AZ. I THINK ELIVATION IS 2000. THANK YOU FOR YOUR RESPONSES.

 

ANYONE?

 

I have the full Yoshi with stock airbox, and no lid. I have 155/160 Mikuni main jets, with the needle on the 3rd clip. 620ft elevation

 

thanks guys.

 

I have a Yosh Comp Full system for my Raptor and a pro design air filter. Anybody know what jets to put in the carbs with drilling holes in the airbox. Also the needle and the air/fuel mix screw???

 

I am running a k@n with full yosh, 155-160 and needle at fourth from top with yosh recomendation for air box holes. it runs well wether or not it could be better? i dont know.
