3 hrs labor ??? if it's a little too involved for you, find a friend who is mechanically inclined and experienced working on cars/bikes and read through some DIY's and take a crack at it. 2 heads is better than one. If you can't get it right, set it all back the way you found it and then go to the dealer to have them jet for you.
3 hrs labor is awfully expensive for something that just requires patience and time
