I am approaching 300 miles on my 05 and want to check the valves. Anyone have any good sites, tutorials, or instructions for help with this? I have never attempted to do it, and not really sure what I am doing. Also, a couple quick questions... - How do you get to the valves, surely you don't have to pull the motor off the frame right? - What will I need, will I need a new gasket set? Shims? - How long does it usually take? Thanks for all the help you guys have provided me and many others. This site rocks!
