gotta 05 trx450r. it has a 185main, 52pilot, full curtis sparks exhaust, curtis sparks foam filter, no air box lid. the problem is that when its idling and u stab the throttle it hesitates and bogs before reving, and when i'm riding and let off the trottle it backfires/pops. i,ve adjusted the mixture screw in and out 1/4 turns at a time and problem is still there. i have changed the plug. i have also changed the plug boot due to corrsion inside where it screws into the wire. wire also had a little corrosion but i just cut it back a little and reused. any help appreciated.
