Please Help!!!! This last weekend I was able to do the famous "BK" mod on my trusty stead. I had assistance from "Mad Potter" (TT name) and I would like to thank him for his help and everyone here for thier input. Now on to the real problem.... CURRENT SETTUP:. I am running a PC-T4 exhaust and with the standard Pilot 2 turns out,stock Needle settup, BK mode .3 or so spray time. (By the way it does not bake fire on deccel) I currently have a 158 mainjet installed do to the fact I ride at 5400' or so. THE PROBLEM: The bike rips from 1/2 throttle up when moving but when making a slow turn and getting on the gas it about dies? I was practicing on clearing some table tops and as I was about to land I would wick the throttle to unload the suspension and the bike would just about stall out completely in the air!!!! Talk about a scary moment when it about launched me over the bars!!! I checked to see if anyting was in the bowl that could be blocking the main but nothing was to be found? I tried moving the neddle position thinking it was not getting enough gas but it made it worse? So I called it a day. Once I got home I pulled the plug it was BLACK!!! I had just installed it yesterday too when Mad potter and I fouled one ( Ooops ) The plug looks carbon fouled--It looks as though the gas is burning but like there is just to much fuel??? I thought when you did the BK mod you had to increase the mainjet size for the lose of all the extra fuel. I only thing I can came up with driving home is the float bowl height is off? Does the float bowl effect this problem? And if so which direction do you adjust it? I would greatly appreciate any help I can get.
