Here's the situation, traded my 06 summit for a 99 700srx, ran whne i got it but kept backfiring. I've gone through the posts, pulled the engine, tore it down re-sealed the engine completely cause there was nothing wrong with it, crank welded and not out of phase. Wife found a few rub through wires so we went through the whole harness and fixed all broken areas. I cleaned the carbs out many times with my ultra sonic cleaning tub, synced and back on. Fired it up and still backfiring. bought new yamaha coils, installed them and still backfiring. Bought 2 used stators of working teardown sleds and still not working properly. Fires up with fuel down plugs and dies but sounded good while running. Any help is appreciated, i'm ready to get rid of this nightmare and stick to my Mach z.
