Hi, bought a 2nd GSXR from a buddy with the intent of turning it into a track bike. He said it's been sitting for about 5 years with gas in it :-(. Went to empty the tank today and found some minor surface rust in the tank and what looks like crystals? Got as much out as I could with a siphon, none of the gas was gooey, all liquid What is the best way to deal with this and make sure it doesn't get in the gas pump and fuel injectors? Thanks for any advice!
