Actually, the reason I bought it was because it only had 4k on it, runs beautifully (starts on the first or second kick every time) and the price of $400 seemed like a pretty good deal. Almost makes it worth all the crap I've had to go through to get a title. I appreciate the reply, I just wanted to make sure before I hacked into the rear section of the frame, that it wasn't something terribly rare, being that I hadn't seen many with the square tank either. In which case, I probably would have left it go, and gotten an RD or something to modify.
Thanks a heap,
