My 99 banshee has a bogg when I start out in first. To get it to go without bogging you have to rev the engine and get the r's up then go. You should be able to let the clutch out slowly and have no problem taking off, like my blaster does.

What should I do or change?
The idle is really slow. Should I speed it up to help it.
I am running the 200 main jet and air screw 2 turns out. I haven't had the carbs apart, but I would assume the needle is at the 3rd setting because the bike is still brand new and thats the setting from Yamaha.
Any Ideas?
Thanks

 

that low end bog is normal for a stock Banshee. You'll get used to it after a while. If you want to solve the problem get a set of pipes and sliencers.
