got an 06' 800 ptek with 1800 miles in. Been perfect all the time except for today. Got a flat spot in the throttle from 4000 to 5000, idles fine from 1500 to 4000 and rips from 5000 to 8000. Tried the heated carb thing, nothing. Tried dumping in iso heet stuff. Plugs are normal color. works perfect when cold but when it warms up it gets the flat spot. Rode in lots of powder around 25 all day. Got the air filter sock on and had the ecm update with new 07 needles. 440 mains. Thinking it has something to do with DPM or ECM because it only does it when it warmed up. any ideas?
