2008 XP 800 X 154 with stubborn midrange bog.
Looking for any ideas.
Symptoms: Holding throttle at 1/4 open at around 5500 - 6000 rpm motor loads and loses power. Power returns once passing 6000 rpm. Motor runs strong below and above these rpms. Happens only under load while riding.
Here is what I done so far:
Replaced DPM - Tested and verified ok
Checked carb connections -- ok
Tested and verified Temperature sensor on ECM connector -- Matches OEM spec.
Replaced rollers in secondary
Cleaned and inspected rave valves
Replaced reed valves with V force
Considering replacing carbs at this point .... Very frustrating![Face Icon Small Confused :face-icon-small-con :face-icon-small-con](https://www.snowest.com/forum/images/smilies/old/face-icon-small-confused.gif)
