So I have had the cams out a few times and need to know how I make sure I am on the compression stroke when installing the cams. Is there a wasted spark and no overlap when the cams are spinning or do I need to make sure I am on the compression stroke before I install the cams back in. FYI...the shim Tappet set up Polaris has with these units is silly...costme $100 for new shim/tappets instead of just grabbing the 9.48mm shims I have in my kit. frustrating.


Thanks for any help!
Joe
