Any one make a larger tank for the 2000 1500 Vulcan Classic? My wife07 900) and I(1500) went on a long trip last weekend. I spent more time fueling up. Besides her getting 50 to the gallon, the extra gallon of fuel the 900 takes, she runs circles around me disatnce wise. . I sure could use an extra gallon on my 1500. The 4.2 gallon tank doesn't cut it. I'd like to aleast get close to 200 per tank. Now,I'm lucky to get 140-160 per tank.
