I've had my new bike running for two days and I've noticed if i twist the throttle all the way all at once it bogs down and wants to die. I have an extended intake pipe so should i need to adjust the fuel/air ratio because of that? Or is this normal for breaking it in, it's been so long since i broke in my first bike i don't remember how that went. Thanks for any help.
