I'd suggest cleaning as well:  SeaFoam can only dissolve minor deposits of varnish, and having run it through twice, that's about all it can do for you in the gas tank...  Be sure to run it once a month, after cleaning, for preventative maintenance, to absorb any water, and dissolve any varnish forming.

I'd also recommend running it through the engine, and transmission, by adding the proper amount to the engine oil.  Run it long enough to warm the oil, shift through all five gears, and then change oil and filter:  the i>SeaFoam will dissolve varnish, carbon, and other crud within the engine, and the transmission, which will be caught by the filter, and it will be suspended within the oil.  If using modern oils (SN, or better; the standard was around SF when this bike was made), you will likely never need to do it again.  You will know it is working if it turns your oil black -- that's the crud.  Cheers!
