I got a 92 polaris 500 indy classic L/C. The head gasket went on it so i replaced it. Cleaned the carbs. Now it runs fine except it smokes alot. It smokes even more if i take it for a little run around the back yard. And then when i take it back to the garage it is extremely hot. Please help with any suggestions !!! I emptied gas tank out and put new fuel in.
