After talking with ivan he had me send back my needles to him. I was running a full akrapovic exhaust system ivans jet kit, airbox mod and k&n filter. Ivan thought that maybe I was running the standard needles set and not the needle set for the race filter and k&n filter. I sent the needles back in for him to measure and come to find out I had the wrong needles. So there are two sets of needles for the carbed r1`s that he makes. The smaller tapered needles are on the way. Dont know when I will get to ride the bike due to the frigid weather her in Ohio but I will post an update explaining how the new needles perform. They are supposed to lean out my midrange and richen up my topend. Supposed to give a 3hp increase up top with the filter and airbox mod. We will see.

I measured the old needles with digital calipers before I sent them off. I am going to be able to measure the new ones. I will keep you posted.

Yeh at one time when I first called to order them I think that is what I was told too, but it was too far back to remember exactly. I think that maybe he revised his needle for the airbox mod. I am giving the benifit of doubt.
