Idle/Bogging Issues
 

So this Hyosung sense I was brought has a brand new carb. Won't start unless I choke it with my hand, and even when it is warm I still have the same issue. Won't rev without choking it for a second with my hand, wont idle at all.

Any suggestions on what it may be?

Running way lean it sounds like, for whatever reason.

Hmm no air box maybe? :D

That will do it. Put it back together and tune the carb...

lmao Yea that could be it..

drop the needle all the way worked for my new carb bro. its flooding! tune carb screw all the way in and then back out about 3 turns if its a 50. good luck
