Adjusting the Intake Side Valves
As on the Exhaust side you need to loosen the lock nuts
Shown below are the lock nuts on the Intake valves

Check the clearance using a 0.15mm gauge - shown is the BMW one.
Adjusting the valve.
Place a 0.15mm feelt gauge into the valve that is not being adjusted - this is to eliminate any rocker movement - this is exactly how it was done with the exhaust valve; except now you use the required feeler size for the intake.
I check the amount of pull on the feeler gauge by setting the wrench in such a position that it does not move when I let it go and then pull on the gauge.
I control the tension with the 3mm allen - once set then I tighten and re-check.
Once set repeat the process for the other valve, except now you swap feelers.
Take your time - don't rush

The goal is to be as close to each as possible.
If both have the same amount of drag then the Clutch Side Valve adjustment is complete and you can proceed to the Throttle Side Valve adjustment.

Adjusting the THROTTLE SIDE Valves
Bump the bike in gear until you see the following alignment mark shown below.
It needs to be at the 3 o'clock position - if you missed it - bump the engine around until you get it - DO NOT BUMP BACKWARDS!
Please note the alignment marks are only visible from the Throttle-side cylinder
Once set in the position below - proceed with the Throttle valve side adjustment as was done with the Clutch side.

VALVE COVER REASSEMBLY NOTES
Once you have completed both cylinder valve adjustments it is time to put the bike back together.
There are two items to be aware when re-installing the valve covers.
1 - is the o-ring gasket for the spark plug
2 - be aware of the shouldered bolts for attaching the valve cover to the head.
First the oring
Make sure it is clean and prepare to install on the inside of the valve cover.

Mount o-ring onto the valve cover
Special note - the valve cover screws were not installed - they can not be removed.
Please note how they are shouldered - more details to follow
Close up of the shouldered bolt for the valve cover.
The imporantance of this is that as you are tightening you will bottom out onto the head. once there do not continue to tighten.
Prior to mounting the valve cover you need to reinstall the valve cover gasket.
A couple of things to be aware:
- it is very robust, take good care of it and it can be installed many times
- it is directional - it can not be put in incorrectly.
Installing the cover
Note that the spark plug gasket can move during the installation process so it is very important that when you put on the cover it is not canted in any way.
Go straight in and then as a guide align the top two valve cover bolts.
Once the bolts are touching start them by hand - ensuring proper thread engagment - and tighten enough so that you can then start all the other cover bolts.
Be aware that the valve cover bolts have washers with gaskets that move around all over the place.
Ensure you have proper alignment before final tightening - this will prevent oil leaks
Example for properly secured bolt - repeat for all 4
Tighten diagonally opposite to 10Nm.
Note - I tighten them until the shouldered part of the bolt bottoms onto the head.
Once the cover is on - install the spark plug.
Torque spec is 20Nm - I set them for hand-tight
Once the spark plug is in push on the spark plug coil - you will hear and feel an audible "pop" as it seats in.
Install any Cylinder Guard covers that you may have
