OK guys this is my first post. Pry didnt do this right but oh well. I have a 1986 Indy trail. I just converted it over to an xtra 10 suspension and a 136 inch track. Heres where the problems come. After the longer track is installed i can barely climb a hill. Its like i have no power. But when i first fire it up after been sitting outside for a bit, the sled is nuts cant keep traction on packed snow wants to go sideways. Its just a completely different sled whens its not completely warmed up. Once i ride for around 5 to 10 min it just falls on its face. There is no power. Any help will do thanks Oh i have been told it could be the belt getting too hot. After riding pretty hard the belt doesnt seem to be too terribly hot.
