When I got my bike back from the dealership, after having the valve cover gaskets replaced, general tuneup, plugs, oil change etc...($550.00!) Now its is extremely cold natured. With the choke on, (or off) I cant get to 3000 rpm's with massive popping-backfiring, etc..

After 10 min's or so of holding up traffic and embarressment from waking up all the neighbors from the hacking and coughing from my Vance & Hines Straight thrus... its smoothes right out.

How can I adjust without having to go back to the dealership?
