Has anyone experienced difficulties with the charge coils or crank seals in there 85 VMAX. My sled starts and runs like a top until it warms up and then runs like crap sounds like on 1 cylinder smokes quite abit. The carbs fuel pump and compression are all good and i already tried a new coil? dealer doesnt think its the charge coil either because it runs..The choke cables arent hanging up either, Any advice would be appreciated. This is an awesome old sled i might add one of the better sleds in its day. Jeff

Also check the Throttle override switches as that was the problem they had with the 85s .There was an update in 86 your sled may still have the old switches. I would bypass the switches and try that and see what happens.
