When I lean my 03 200 over on the kick stand, with the tank 3/4 full or more, fuel pours out the vent / overflow lines at a pretty good pace. It has done this since the day I bought it. Again, only when leaned on kick stand, and a nearly full tank.
Whats the deal. Common KDX thing or some out of whack floats?
My used 1996 does that too. I don't know if anyone has changed my floats but you should be able to fix it by adjusting the float level. I don't know, I haven't tried it yet. I tend leave the petcock on all the time so it better fix it.
