has anyone had issues, with a carb on a 450r? first of all mine sat for to long i guess cause the fuel went bad, i went threw it and cleaned it out, but it was still acting as if it was over fueling. would idle fine, but when you starting goin it seemed to flood out or chock out. its wierd. so we changed the needle and seat, and put a new float set. put it back on and then it was doin something alil different. this time it would idle fine and rev fine until you put it under a load, then when you would get to about half throttle it seemed to chock out and sputter. so again it comes apart we found the main jet to have something in it so we cleaned it again. now it wont idle, the chock makes no difference and the hot start lever makes no changes iether. does anyone ahve any ideas. i realy need to go for a good ride.
I know on my YFZ it was the pilot jet that was clogged even after we went through the whole thing. I have heard recently that with the new gasoline that even if you shut your fuel off and run em till they die it still leaves enough fuel in the bowl and jets to gum them up. Stabil is apparently the only way to prevent it other than routinely starting it every 10 days or so.

Your latter symptoms( i can keep it running by feathering the throttle. and it will go. and from time to time it startes to go like nothing is wrong ) kinda sound like my 3 wheelie and the ground issue I struggled with.
The smoke however, sounds a little more like bad rings. Have you tested the compression?
No expert here, but tryin to help
