If you want to improve cam chain tension you have to figure out a way to increase tension with rpm.
The OEM's do it with a hydraulic assist. Parasitic drag is minimised at lower rpm where motor spends most of it's time on the street and increases as revs (and oil pressure) go up
Maybe adapt a mini hydraulic damper then replace parts 5&6? (HD used non pressurised hydraulic lifters for a long time)
If you figure out an oil feed the adjusters used in early Victory motors are (relatively) tiny, they fit into the rocker tip
Larger idler wheel will increase tension very slightly but will also totally change the dynamic movement of chain
You can see pictures of motorcycles with drive chain coming onto rear sprocket in weird directions, the inertia of chain coming off front sprocket, lubrication and sprocket sizes all play a part
