I bought a clarke, Looks nice, mounting was a little weird, It had some movement, rode it for about 15 miles, took it of and now it sits in a box. I will experiment with it in the future but it mad the bike feel wide. My knees were below the tank, so the shrouds were the only thing in the way. I will heat up the shrouds and play with it a little further down the line. The gas gas just feels so good in stock form, but I have had milage issues at some long races. I may have worked a few of those things out, and I'll be testing how far I can go without hitting empty. Like I said in the beginning nice looking tank, I just don't think I gave it enough time to get used to it.
