RTV-X110C Going Slow

[Cavitt]

HI Guys.
Our X1100C has started to go slow.... The engine sounds like its revving freely but running on flat ground we only get to about 30km/h (18mph). All oil's are clean and at correct levels, Filters have been changed including fuel filter but nothing seems to be making a difference.
The one thing i have noticed is that the VHT Pressure relief rod is sticking out (just) past the 21.5mm spec in the operators manual and is touching the cam. I'm wondering if it could be releasing pressure effecting the drive performance?
Has anybody got a WSM for it or have any ideas?

18 mph on flat ground is about the best our X1100 has ever done. I can hit 25 mph going down our 12% grade driveway.

Might need some setup Ken45101.
My RTV-X1100C will do 25/26 MPH, verified by my Garmin GPS and the speedo, all day long. AC on or off with my wife and I in it. We do lots of trail riding and roading.

PS....mine has the stock Worksite tires.
