So this weekend was the inaugural run for my Grizzly in Alaska. It proved to be a rough one. I helped a friend tow his skiff across the island with quite a bit of snow on the ground. We ended up hooking our bikes together and pulling the boat that way. About a 1/2 mile from where the boat landing is my Grizz's overheating light came on, so we stopped and let the bike cool down. We ended up getting the boat back to water with no further problems. But after that towing I lost 10mph on my top speed. My low and mid range power seem normal, but I just seem to have lost some of my top speed. I don't exactly now what would have caused this? Is it some major wear on my belt or what? Any suggestions would be appreciated. Oh yeah, I burn oil NOW too.
