Can somebody post these (internal in the engine, not sprockets!)? If you have an 06, they should be in the back of your owners manual. I would like to compare my 04 to the 06. Thanks!

 

Ok, found something in an old post, Since I went to a 13T countershaft sprocket, I am trying to get at how the two years compare.........
