Kenny-

Why take your machine in to the dealer? Checking and adjusting the valves is quite easy on the DS and it never hurts getting to know your machine better. All you really need is a few wrenches, a feeler guage, and a micrometer or vernier caliper. If you search through the Bombardier forum, you'll find all the info you'll need to do the job. Let us know if you need any words of wisdom.[img]i/expressions/face-icon-small-happy.gif[/img]
