Hey guys I recently did dave's mods, d-smogged, d-snorkeled, uni filter and put in a Yoshimura slip on for my 08 L. I also re-jetted with 58/160 and turned the knob 2.5 turns. I am riding mostly at 3,200 feet. I find that now it has much more power but I feel that its not properly tuned because when I open the throttle full it sort of has a lag to it. Plus this morning when turning it on (after a week idle) it blew some black smoke out of the pipe. Is the lag or black smoke because it is to rich? Should I go down to a 55/158?? or should I try first moving the knob around and If so, should I turn it more or less than the 2.5 turns? Thanks, sorry for the novice questions but I am not familiar with mechanics too much! Really appreciate your help!
