Not a full can....remember, your Goldwing only has a 6.6 gal. fuel tank. I use injector cleaner in mine each time I change the oil. Read the cleaner can and see how much fuel it treats and then determine how many ounces to put in your fuel tank.
Fuel injection cleaners are one of the few consumer available products thet can do some good. I prefer the higher end ones like the Castrol Syntec synthetic FI cleaner.
For winter storage I use Stabil for the fuel then drain the tank in the spring, add some FI cleaner and fresh fuel. Seems to solve those startup problems.
Use Chevron Techron (and only Chevron Techron) for fuel injector cleaner. There is nothing else on the market that come close to being as good. Chevron invented and patented Techron, and it is far superior in removing carbon deposits than any other cleaner made. It is also the only cleaner that I have used that I can actually say I FELT a performance difference after using.
You can buy it at any Chevron gas station, Wal Mart, or most auto parts stores for about $7 a bottle.
