it has a curtis sparks exhaust and 165 jet. I have no idea if thats the right jetting for this bike. Its how I bought it. and it was sitting for a while so the carb might be a little clogged I really have no idea. Any help is greatly appreciated.
I would take the carb off and clean it really good. Take the jets out and make sure they are clean and clear of any buildup.
