Well how often really depends on how much your riding and stuff. Theres a post here that talks about when to tune http://www.frostyrider.com/boards/index.php/topic,185.0.html . Yea just about any good shop should do it. How much it costs really depends on the shop and i kinda forgot how much i paid last time but your probably looking at between 25-45 or so. Its extra if you actually need like a p-tex repair or something.
