Im constantly changing between yz and wr timing on my 400, to suit the terrain, but since my last conversion was quite long ago, I lost the red line with the left side cam chain slider rubbing with some force into the chain, not allowing the cam to rotate 100% freely (by hand power), as the intake does

I test it with both cams placed, torqued and chain tensioner not yet applied

Are your cam cap bolts over tightened? :)

no, they are torqued with the torque wrench
the chain is running pressed between slider and exhaust chain sprocket
it can rotate by hand but with a bit force
