Air box mod the Kawasaki mechanic at team moto in albion told me about.
The mod involves increasing the size of the ram tubes removing a set of butterflys and repositioning a sensor. Not much in the way of gains but stops it being out of breath at the top end and dramatically improves throttle response. I rode one today at the dealers that was tweeked and the difference was really very noticable. Keep you posted and get a full write up on what is done after its completed. $ 88 to get it done seems pretty reasonable for a better breathing machine up top.
