Hello everyone I hope someone can help me.i have a 97 kodiak 400 4x4 rode it a few years then noticed backfiring at carb. Found that my intake boot was split. Bought a new one rode for about an hour it backfired again And split the new boot.i bought a new carb and new intake boot. Checked the crankcase breather and it wasn't clogged. Rode it for a half hour and you guessed it, it backfired and blew out the new intake boot.can someone help. Thanks
