I have never seen anyone put a air/fule gauge on a bone stocker,was just wondering if anyone even knows how Kawasaki sets them up. I have the 2010 here and just starting my in house R&D work by welding bungs in both pipes. Didn't know if anyone ever did this. I also want to see what a bone stocker does when you run it down the road wide open. The reason for this is I have a customer that said his 840 takes about 40% more fuel up to 6000 rpms but after that the front jumps up to needing 70% or more the longer he holds it wide open. My thinking is the fuel pump might not be keeping up with the bigger injectors. Just something that makes you go hummmmmmmmm! Could this cause over heating holding them wide open in the dunes?
