I'm trying to buy a yamaha tw200 but my only problem with the bike is the size of the fuel tank . It can only hold 1.9 gals of fuel, but the good thing is the bike will average out 70 mpg . I'm new to adventure riding and would like to bungy a external fuel tank to the rear of the bike, I would hate to run out of fuel in the middle of the boonies . What I want to know is this, does the fuel go bad if it sits in the container for a long time? Sorry if its a newb question!

Yes, but the time to "go bad" is at least weeks. If you need storage for over a month you should add a fuel stabilizer, such as Stabil, to the jug. But you'd be better off to cycle the gas through your main tank regularly and replace the jug's contents instead.

 

Doesn't it have a on/off/reserve petcock?

 

carry a small jerrycan instead

 

a jerrycan is what i'm talking about.
