So i got my quad running again, cleaned and rejetted the carb, idles and runs perfect except at full throttle it bogs down. I noticed that when it does this the air inlet tube on the air box sucks it's self against the gas tank. I shoved a piece of wood between tube and tank and it does great at wide open throttle. Has any one else seen this before and is there a proper fix. The intake and box are same as the 500.
