So I now have a 2006 rmk 600. I was checking to see what rpm's the clutch engaged at. It is engaging at 4200 rpm's. I thought that it was supposed to engage between 3100 and 3500 rpm. If anyone can help me with this that would be awesome. Getting supper excited for the snow to fly. Also on another note I was thinking of putting more vents in my sled. Is it possible to make ur own vents? If so what would they be made out of? What is the best placement for new vents? Anything helps thanks
