I have a '99 RMK 700 with the x-tra 10 136" skid that came stock, and have purchased rail extensions that will fit a 156" track. My primary question is whether a tunnel extension is needed? If my math is correct, the track should be effectively 10 inches longer at the back. The current tunnel is slightly longer than the track. Here is my main question: With modern snowmobiles, everyone is cutting tunnels. I'm not worried about dragging my tunnel, this thing isn't doing wheelies for sure. However, if i don't need to order a $100 extension and the exchanger will get enough snow, then why not just shorten the snow flap and leave the tunnel stock? Any thoughts are appreciated.
