Bike will run great on new plugs, but foul and goo after 20 miles then run bad. Went to parts store for new plugs, asked why bag plug foul? He looked at and said looked like antifreeze foul, said"sell, smells like antifreeze and looks like antifreeze foul.
Now what do? Michigan riding season running end. Head gasket? Ebay has cheap to good, $20 to $70. Old, end of life bike. How hard change. One day job? Have drop engine? Am I done for season and all winter job?

I You Tube. Saw video on additives to coolant for headgasket. Looked promising, maybe good enough make through season and tear down over winter. How hard to do replace? Already endless work on this. Replaced engine 3 years ago with one from Massachusetts. Replace antifreeze before additive?
