Jetting Help

[booboi]

OK so I received the alba pipe kit for a early Christmas and got done installing it 2days ago.
Me and my bro put main and pilot jet in and cleaned out the carb.
And now the bike is running good, however when I did a run around my block it backfires not alot but just enough that i can hear it.
It only backfires when I reach the top end of the gear im In and shift.

So we call check albas website and it told us the following

"Fuel Screw - 2 Turns (approx)"
Now my question is were is the fuel screw? and will doing this end my problem.

Your few screw is at the bottom of the carb. It will be where this is just up inside the carb.

sounds like to me it's to rich on the main.. if you have it reved out full throttle and it the engine starts to miss or stutter then to rich.. back down one size at a time until it clears up.
If it backfires when deccerating all the way off the gas then its lean on the pilot jet or fuel screw.
