Anyone know anything about Startron Enzyme Fuel Treatment? I've been adding an ounce to each tankful hoping to smooth out a lumpy idle when cold and having to mash the starter button for up to three seconds. It appears to have worked where nothing else I tried (Lucas Upper Cylinder Lubricant with Injector Cleaners and Fuel Conditioners, Kragen brand fuel injector cleaner, SeaFoam) worked for very long. Now the bike starts up with just a touch of the starter button, and the lumpy idle is better (although not as good as when new).
Anyone know what's in it?
Could it be my O2 sensor that's messed up? It smells like it's running a bit rich when cold, but when it's warmed up, it seems to be alright.
