My '90, 900 starts right up on cool mornings, but runs rough for 1 to 2 minutes. We're also noticing that we need to add fluid to the antifreeze fill tank - 1/2 gallon twice in 2 months - notice it when the heater doesn't put out. Once a little warm, the engine purrs. Is there a possible connection? What would I look for if there was a bad head gasket? Seeing no discoloration in the oil. Dry gas and injector cleaner might be helping. Any suggestions? Thanks
