08 420 rancher420 es 4x4 running bad
 

after about a mile or so of good running and the bike getting hot i cant use more than half throttle, if i do it acts like a carb clogged up would. then i can cut it off and sit for about 5 mins and it will run good for a min or so then goes to acting like it is n ot getting any gas. any suggestions?

We'll its definitely not a carb issue as its Fuel Injected. Mine ran very crappy due to a very oily air filter. Check your air box. Are you getting any fault codes (series of blinking lights) when you turn the key?

No no fault codes.I was just useing the carb saying as a refrence to how it's running.the air filter is also good first thig I checked.I'm a mechanic but not familiar on how this injection system works.I'm figureing a sensor is going bad since t has to be hot to screw up ad then after sitting for a few mins it runs ok for a very short while. I have the 4 year extended warranty but don't really want to take it to the shop and wait for who knows how long for them to get it fixed till I know what part is bad
