Hey man just wondering if you could help me out too. I got a 06 with FMF Gnarly exhaust w/ turbine core 2 silencers. It was bogging down and then fouled the left cylinder plug. I changed plugs and put a toomey air filter and outerwear (no air box) on it. It runs good but wants too bog when you are not getting into it hard. I got the whole system with a jet kit that came from washington state and I am in North Carolina. I am not sure if that jetting will work here (sea level, maybe a little above, 32 degrees at lowest). I've got to find out the exact specs on the jet kit but just from that info do you have any suggestions of what I need to run as far as jets and is that the reason it is bogging? Thanks
