I just put an IMS 4.6 gallon "see through" tank on my '01 650R and there is about a gallon of fuel in the low, left side that dosen't get consumed. If I shut off the petcock and lay the bike on it's side, I get some fuel over to where it can be used, but much dumps out of the carb. and much stays to the left,below the petcock, out of reach. Any suggestions? I feel stupid, hauling around a gallon of gas that I can't get to.
