2008 Ultra LX - Cant Make Max Speed
I have a 2008 Ultra LX with about 50 hours on it. Running great until this week when I noticed that it would hesitate when accelerating to full throttle for a moment and engine had a miss when at idle. Pulled the spark plugs and they looked OK, but replaced them anyway. The hesitation and miss are gone and seems to have full power, but now max speed is about 42 MPH when it used to be about 52. Max RPM is 6500.
Would really appreciate any suggestions on possible cause for decrease in speed.
