I had a perfect one on my bike until last week. I live and travel in a motorhome and I have a car hauling trailer that I use to carry the bike and a Jeep Wrangler. I was unloading the Jeep and just as the engine started my foot slipped off the clutch. The Jeep jumped the chocks and slammed into the side of the bike and put a pretty awful crease in the tank.
All the correct tanks currently for sale on ebay are in pretty shitty condition and going for around $300 plus shipping. I hate to pay that kind of money for a tank that'll take another $300-$400 to body work and paint. I placed an ad on this forum but no answers yet. At least I can still get the 10th anniversary stripe kit from Vintage CB750 ($150-ish), but I need to find a nice tank first.
