Now that the freeze-a$$ weather is finally upon us, the bike of course sits for up to 2 months (maybe more depending on my travel schedule). I rode today, but the snow is coming.
Back when I needed to store a bike for up to 6 months...I would always drain the gas...but these were old scoots sitting over extended periods, carburetors, etc. Never really knew why, but the old timers told me that was the way.
So - Is it best to have very little fuel in the tank or full when storing? Does it really matter with today's fuel and tank construction?
+1 on the "full" - plus add some fuel stabilizer (Sta-Bil works well). If you add the stabilizer during your last ride it will find it's way through the entire system and prevent varnishing from the stagnant fuel.
As others have said...full to the brim, throw in some Stabil or Seafoam (that's what I use) and run it enough to get it through the system. Then put her to sleep for a few months
