i dont know how far a 503 will go with the small tank,so if anyone has a 8 gallon tank they arent using give me a call 406-370-4960 Bud thanks. Maybe it will go as far as a 600 ? on half the gas huh?
when i ride i usually plan 8-10 miles to the gallon....with a 4 gallon tank...dont pass a gas station without filling up! or atleast have a tow strap handy
keep an eye out for the big tank,that way you can worry about ridin and not the nextgas station! check whitesurf.com i think he has a big tank for sale on their site in used parts....
