Troy lee pred 500 help
Hello guys I’m new to here and been trying to slowly build up my predator. Anyway I just put a trinity stage 4 full exhaust and air box mod till I can find a better mod for air intake. I’m have good idle and a slight dead spot when I first hit throttle and a backfire and a flame out exhaust when I decel from full throttle. I didn’t get any jets with the exhaust or and recommend sixes. Trying to get rid of the backfire any suggestions? Running 45 pilot 155 main needle on 4th slot from top.2.5 3 turns out on pilot screw. Thinking 50 pilot 165 main? Any help would be appreciated thank you in advance guys.
