I got to take my bike for the first ride since putting the new WB E exhaust on and installing the JD jetting kit. And wow what a difference!!!! It was seriously like a completely different bike-unbelievable!!! I had been dissapinted with it prior to this, but now Im grinning ear to ear. It feels like it should, crisp and oodles of power. Pops the front wheel no sweat and pulls everywhere. If anyone is still running stock jetting and exhaust you HAVE to get rid of that crap!!!!
