2000 1100 spirit Fuel Cap
I just acquired a 90% parts bike which is a 2000 1100 spirit. Using parts on it for my 94 shadow 1100. I swapped the tanks around and the parts bike didn't have a fuel cap. So I tried using the cap off my 94 and its fitting loose. The notch inside the bung is much wider than the one on the 94. So i tried a cap from two of my 600s and those were loose as well. Any idea why? The bung shows no sign of being tampered with. Its just wider than all the rest. Did some internet part searching and all the part numbers for the fuel cap are the same for 94 and a 2000. Soooo?????
