I think the Scram is needin a valve adjustment, since it hasn't had one for a while. I just have a couple questions...

How often should I have the valves adjusted?
How hard is it to do? I want to learn how, and I have the full detailed manual and a couple books on how to do it, but I don't know if I would be better off taking it to the dealer than teaching myself. If I had someone to show me how, then thats another story. Am I better off taking it to a dealer?

They're kinda stupid questions, but thanks for any help.

Also...how much should I expect to pay for a valve adjustment from a dealer?
