Someone who rides harley told me today that if the bike sits for long time, inside the gas tank will get some sort of "film" and it will eventually starts to clog the fuel injector. He was talking about the time when he shipped his bike over from CA to Hawaii, so talking about a month. Have anybody hear such a thing?

 

Not sure about the film, but my bike sat for a year and a half with the same gas in it, I am guessing just before I bought it. We drained the tank, and put fresh gas in and the bike has been running great for the last 3 years for me.

If the bike sits for any length of time, I know the gas will start to break down. So I would drain it and replace it, regardless. Cheaper to replace a tankful of gas, than carbs and whatever other problems bad gas will cause.

 

You can get a varnish from the gasoline evaporating, but this is more an issue with
small openings, etc. i.e. injectors and carberator jets.

The main issue you'll get in a gas tank is condensation on the walls of the tank.
That can cause rust, eventually.

The best solution is to top off the tank, if you anticipate a short-term storage.
Adding Sta-Bil is also recommended for seasonal storage.

Draining the tank completely and leaving the cap open (with a rag to prevent dirt
entering) allows the tank to breath, for long-term storage.

If you're concern is the short time you've been laid-up,
I don't think any lack of attention is going to have been a problem.
Your baby should be just fine.

If you're worried, run some Seafoam through it, but I think Madhattr's right as usual

 

MadHatter is right on! Only thing , I swear by Seafoam. It works as a cleaner, and stabilizer, and has many uses, even in the oil. I use Seafoam constantly in my boat , and every 3-4 tanks on my bike, it keeps everything clean and running great.
