What BRAND of fuel are you using?

[Suzuki Stevo]

I'm almost sorry for laughing at this... almost. put any modern untreated fuel in a 1/2 filled tank for three months, then come back and look at it. yeeouch.

It was treated and still didn't make it to spring, I never have this problem with Tier 1 fuel, Chevron Regular will last over a year treated.

I don't really stick to a brand but I put "premium" in my tank. It's higher octane (which doesn't really matter) but the important point is it's way cleaner. If you take the premium fuel in a jar and take the regular unleaded fuel in a jar the regular unleaded fuel is far more dirty. This is more of a local problem and not a problem with the GSes.

The result of not switching sooner was it gunked up my carbs and gas tank over time because I didn't have a fuel filter.

you're telling me you can see dirt in unleaded, but not higher octane unleaded, from the same station ?

they're leaching fuel into the ground then, and you should call the epa !

That could be the case. I'll have to do a few tests at the nearest gas station to be sure. I didn't even think of that. It happened once (the time I decided to switch to premium after cleaning my carbs) and I just never bothered to check again  .

you can try  testing  that theory if you like, but I'm not in my bikes.

I was told not to use premium on my old ZZR(98) so since then I just use 91  mainly caltax (ww) or shell if a shop at Coles . Same as my cars.

So the fuel does make a difference in some ways then?

Dammit I'm out of popcorn.

Quick dash to the 7/11 then?

I'm a stones throw from Canada, it's cooler up here, your closer to the equator, much hotter, (heat and gas..not good) what works for me, may not work for you? Now theres a theory you can try and wrap your opinion around 

[slipperymongoose]

Ooooooooohhhhhhh snap

[Janx101]

  theres gonna be phonecalls now!

If my bike sits for a month, I just drain the fuel and put it in one of our cars. In sealed systems in modern US spec cars, I have seen fuel work fine after over a year, but that is in sealed evaporative emission controlled cars. I have also seen a 240Z that had all the exhaust valves stuck open with varnish like goo from bad gas that sat a year while the owner was on deployment and that was before ethanol gas here. The old leaded gas would still work after a decade.

Guess they don't make fuel like they used to

you mean like "will the bike run without gas?"

ya, that matter.

I'm learning with your input

I'm not sure if its just the humidity level or that with large temperature swings, or completely unrelated and only the mix of junk put in fuels now... but yes, down here leaving fuel for three months is a bad idea.

With ethanol fuel in a vented tank, humidity can quickly become a problem.
