2004 edge sport touring loses power after warmed up.

[laredoggg]

I have a 2004 sport touring that used to do 60+ mph. Now it only gets up to 55 mph then loses complete power after warming up. After it cools down it will run good again until it warms up. The psi is 120 in both cylinders when cold then drops to 110 psi when warm. The carbs are perfectly clean. Could this be a clutch issue or ??? Thxs

Might be a carb boot issue, or seal arround crank

Thankyou for the reply. I did spray around the left side crank seal and the boots with no idle change. Could be either ? the sled does have 5400 miles. I'll tear into it again when the weather warms up above zero degrees. Much appreciated diagnosis. Thxs

I would clean the clutches and definitely replace the springs, those 18yr old ones in there are bagged out by now and likely not giving you full backshift which could be causing excessive heat to the belt.
