Hi guys , bike now fully up and running at last.

Just need to check headlight beam levels. Is this easy

Beam levels?

You mean where the headlight shines?

Not really - MOT places have special sighting assemblies to check this.

However, it's usually very easy to correct. On my bike there's one screw that controls the up/down and one that controls the left/right.

When doing the MOT, stay with the bloke and have him talk you through the checks.

Unless he's a complete c**t, he will correct (or let you correct) the simple/minor stuff like this right there and then, thus allowing you to pass MOT!!
