Knock on my idler wheel?

[TheTruth2]

This is weird... I shoot a heli-m and whenever I draw my bow back For THE FIRST TIME there is a knock on my idler wheel. It only happens the first time I draw back when I start practicing. I have no idea why? Any ideas?

How do you store the bow?

[TheTruth2]

Wall hanger same as u would in the tree. I've started to lay it in my case since the knocking started

[asav2013]

is it almost like a click noise? or  a pop? on my evo it had the adjustable cams where ya could change your draw stop and some allens and change your draw length with out a press, I know yours doesn't have this but after tighting down those allen screws the first draw would make that noise it is just the screws and string falling in to place , I would take it to your bow shop and ask it may be something it may not but with expensive equipment it never hurts to ask before it becomes a expensive problem. good luck

It's kind of like a click I suppose. yea that's what I figured it would be is the string settling on the wheel. What concerns me is it never used to do it. I take it to a shop and see what they tell me

Same thing happened to my reezen 6.5 it ended up being a bad cam bearing . Is there a lot of cam lean take a pic of the idler wheel from behind make sure the string is in the pic

i had a similar issue with my hoyt, though i thought mine was coming off the top cam. turns out it was the limb pockets. pro shop lubed everything up and its nice and quiet on the draw even in the cold

I would have guessed cam bearing, but I could see the limb pockets causing noise if the rocker is dry.
