Okay, so I got a new to me RXT X 260 about a month ago with 32 hours on it. It has run unreal. However, the past two- three hours on the machine, I've noticed a bog in the acceleration and maybe a slight drop in top speed. If I pin it out of the hole, it goes hard to 20mph and from 20-45 it's still pulling hard but falling on it's face off and on until about 60. After 60, it's back to normal and feels like it has full power. It only topped out at 67mph today on a half tank and calm waters. Two weeks ago I had a steady 69 on the speedo. I noticed today that the bog was also around 6,000rpms in between the 40-55mph range. Any suggestions before I take it to the dealer?
