I do not have the gyrt book in front of me. Is that jet kit a dyno jet kit that yamaha relabled?? Or is it just different needles and mukuni jets?? Does anyone have a different needle that works with the stock mukuni jets?? I need a needle will more taper (more fuel) than the stock needles. I am jetted 200/200 right now.

 

I think they are mikuni needles with more tapper. Mikuni jets.
