I own a Corvette repair shop been sucking out gas tanks for years it works great. I drain as much as I can then stick the hose in and get the rest. My shop vac always smells like gas for some reson lol.
Somebody want to do this and post it on you tube? I need a good laugh!
Don't leave it in the tank, even though you should have no problems. If you don't want to pull the tank, have your dealer do it. These bikes deserve to be maintained and repaired properly.
I'm not much for working on my own bike so taking the tank off scares the hell out of me. I might try the speaker magnet, worse case, if I can't get it out will the bike be okay?
honestly it's pretty damn easy, don't over think it, it's a couple screws. to drain the tank not sure if your bike is carb'd but if it is pull the fuel line off the back of the carb and put a brake bleeder on the petcock vacuum line for the fuel to drain, then just pop the tank off and shake the screw out.
