It's funny when I first got the Busa I told my wife that I won't be making any upgrades, there was no need. But after replacing the stock exhaust.................. well you know how the rest of the story goes. The gas cap is made by Harris it looks great and works even better. I've got a couple of more pics to post, especially one of my Battery. It's made by Speedcell and only weights 1.7 lbs. that was a quick 10lbs weight loss, a little expensive at $250 but Hey welcome to the world of high performance motocycling. Again I appreciate the comments, Thanks.
