NO IT DOESN'T!!!!!! the self leaning issue still exists, not as bad, but it DOES exist. The problem is a lack of back pressure along with a gravity problem. The bottom half of the tank is too low and the exhaust pressure isn't high enough to push the fuel up to the carb.

The only solutions are; A 2nd tank installed so that the exit to the carb is around the same height as the carb inlet
Change the stock tank for a buggy style OFNA tank
Move the tank somewhere a bit higher, like the top of the radio box (this would probably mean a tank change also, as the stock tank would be unsightly(because of it's shape) and very hard to mount)
