Also I'm full loose on all belt tensioners.
I was assembling my yz4 today and noticed the belt tension was not changing much moving the rear tensioner forward or aft on the wide belt. I installed 3mm of shims between the tensioner mount and top deck and still have plenty of room to get my shorty pack in and out. Should I adjust the tensioner all of the way forward to get the belt as loose as possible or is rearward the loosest setting? This is the stock wide belt btw as I am waiting on a backordered narrow belt kit. Right now the front belt is a bit tighter even with the top deck tensioner removed.
