Yes, thanks Dudes for your replies.
Based on @cmoalem shared video link I found some additional videos and I found that these gears have this kind of wear too.
I was not able to find out what grade this wear was because its a video - but it is wear.
And these cam replacements are made with less mileage then my bike has.
It seems for me that it will not be so dificult to replace this outworn gear, but I wonder at what grade of wear the point of replacement will be reached.
Indian is using what Cummins calls scissor gears.Allows a spur gear to run quiet with no backlash.You may be just seeing the difference between loaded and unloaded sides.If wear can be felt with a fingernail then you have an issue if not it's strictly an optical trick.
