Of course my bike is new just had the break in service done but....try to learn how to do my own valves next time....
I use to do to the valves on my air cooler Volkswagen so this should be about the same or close to... questions...

How do u find TDC....Mcdonalds straw???? Please explain how to use this tool..
Service manual say to remove tank, I have heard you don't need to???
Service manual list inlet and outlet valves...I assume the inlet is the one closes to the throttle body and the outlet on is next to the exhaust pipe..???

Is there a write up somewhere on this with pictures, tried searching no joy...

thanks

Dan
 
There are a lot of writeups on this, but I'm not going to be the one to find them. However, a couple of pointers I can give;

1. The straw can be used to find TDC. You remove both spark plugs and valve covers. Pull the plastic cover on the front of the engine and rotate the 22mm? nut clockwise (when looking at the nut) to rotate the engine. Put your finger over the spark plug hole on the side you are trying to get to TDC. When the air is coming out, the piston is on the compression stroke. Insert the straw into the plug hole and continue slowly turning the engine until the straw just stops rising. This is TDC. The straw is the tool of choice as it will not break off in the hole like a pencil or chopstick, etc.
2. You do not need to remove the tank to get the valve covers off, but you DO need a set of ball end allen wrenches. You cannot insert a regular allen wrench straight in, but a ball end wrench works at an angle to remove the two top bolts. Take care to not drop these bolts. I use a "magnet on a stick" to assist with this operation.
3. You are correct, the outlet (exhaust) valve is the one at the front, near the exhaust pipe.
4. Always adjust the valves with the engine complete cold.
 
I just pulled the spark plug out and looked through it with a light, when the piston was all they way at the top and barley just started moving down maybe 4-5mm I measured and adjusted the valves.
 
Wistrick,

I have a document with step by step directions and pictures. I think I got it off of this site, I searched and couldn't find it again though. I'd repost it but I didn't save the name of the original author. It's for the Breva 1100 but should be the same for the Norge. PM me your e-mail address and I'll send it to you. Or I can get it to you this Sunday if you're going to make it over to my place.
