I've got a 2014 xm 800 with 900kms, installed a y pipe and a can, now it has a bog, backfires around 6500rpms (no codes coming up)(already changed the plugs and index them), stab the throttle a couple of times and it clears up holds 8000rpm, could the y pipe be leaning out the mid range?(not suppose need any programming) any other ideas? power valve stuck? tps? broken reeds? is there any way to check/inspect the exhaust valves with out having them calibrated by the dealer?
