Help please, I have made the following changes to a stock 2009 crf150rb that ran flawlessly. I put on a FMF powercore4 slip on, quickshot 3, JD jetting kit - 145 main, 42 pilot, red marked needle fifth down from the top, 1.75 turns out, thin o-ring, the fuel I usually ran is a 50/50 mix of 93 octane and cam2, and a new twin air filter and I did this to get a little more umpf. I just ran all the changes at a hare scramble at 1,000ft. elev. and the bike was bogging on hard throttle twist, and when stalled it would not refire, at least 100 kicks and all the tricks for starting a hot bike and at point spectators helped push start me. I know I made the cardinal sin of changing to many things at once but felt the performance changes were not that much. After dropping all the cash on the improvements I would hate to go back to stock. I appreciate any help, thanks.
