Timing after "DOO" change?

I ordered MIKES DOO kit today. I pulled cover off,,,,looked inside and spring still intact,,{23,000 miles} the adj lever still in one pc,,at least what I can see of it,,,took adj bolt out,,,and in the slotted area of lever there was a "circle step" worn into the lever from the head of the adj bolt, so in essance,,the past 5,000 miles or so every time I thought I was adj the DOO,,,it really wasnt moving at all!!!! So my question is: When the new DOO goes in, wont that change the duration of the valves opening and closing? Maybe not much enough to worry about?? Thanks again.

Changing the "doo" will not affect the valve timing. It just maintains proper balancer chain tension.

Does this de-mystify things a bit? The cam chain runs on it's own circuit, near, but independent of, the balancer chain circuit. Ideally, you will not remove any of these chains. You just remove and replace as the doohickey instructions direct you. The cam chain SHOULD be untouched, unaffected and exactly as it was before you opened the cover.
