How do you know you have correct chain tension with this manual adjuster?

Here is the adjustment and installation instructions directly from Tokyo Mods, if you require more information it would be best to contact Tokyo mods for further support: 1) Please read all instructions before starting the installation process. If the installation process is more than your current mechanical ability, please have a qualified technician install it for you. 2) Rotate the engine to TDC (Top Dead Center) Make sure the engine is not on the overlap stroke, See your shop manual on how to find TDC for your model. It is best to remove the valve cover to be absolutely sure the engine is at TDC, compression stroke (Cam Lobes Facing up) and not on the overlap stroke (Cam lobes pushing on valves). 3) Remove the stock cam chain tensioner. 4) Install the Tokyomods tensioner and just start the two 6mm bolts so they go about halfway into the cylinder Do not tighten them at this point!! 5) Adjust the center screw until it touches the cam chain slider in side the engine at that point continue screwing the center bolt in until the tensioner body is 2mm away from the cylinder. This will give you 2mm of preload on the chain when the 6mm bolts are tightened 6) Tighten the two 6mm bolts and torque to spec (7 lbf-ft) 7) Tighten the lock nut while holding the center adjusting bolt, Being careful not to change the preload adjustment. The installation is now complete. Remember this is a mechanical tensioner, it will need adjusting from time to time. The adjustment should be checked after every 5 hours of riding. This is only a guideline, depending on the condition of the engine and type of riding, it may need to be checked more frequently.
