I religiously cleaned this thing, it's spotless I can even see through the jets in the light more clear, I got fed up and sold the bike.

After the cleaning it pours even more gas!

please help.

not sure if this is the case here- but I can't tell you how many carbs I had to rebuild after the owner took 110psi and blasted out their carb- then complained about overflow issues.Most common fix- they would always blow out the seat where the needle sat; so when the float raised the needle, the oring or copper / brass seat was missing and it would allow gas to just pour out. Make sure you have a fresh plug in that 2-stroke also- a fouled plug will cause rough / no idle issues and 2-strokes love to foul plugs.

I bet your right, I THOUGHT I saw something fly out when I blew out the needle sleeve but couldn't find it haha so I thought it was my imagination. Will keep this in mind next time, too late now the bike has a new owner to deal with. I got an lt250R to deal with now
