I bought a 600 H.O. it rides and handles like a dream, but I just do not seem to get any juice out of it. The dealership told me I needed to have 10hrs on it before it would kick in. Well 10hrs has come and gone, now they want me to buy this and that to enhance the performance. I mean it tops out at 60mph. I have 1997 340 puma that goes faster than that. Any Ideas or solutions?
