3rd gear slipping on high torque

Let's take a look at the adjustment
Post both upper and lower pictures of the adjustment cables.
What do you mean exactly?

In relation to the other answers, the slippage is confirmed to be just I third gear by a friend bike mechanic. So it couldn't be oil or adjustment related if I understand the mechanics a bit, or could it?

of coarse i have been a mechanic for about 60 years and a mechanics shop for 50 years.
 
Based on your description of what the "SLIPPING" feels like in third gear, you have a problem with the clutch as Kevin stated. A defective gear set would skip (broken teeth) or jump out of gear (worn dogs). You stated "the bike's rpm increases, but the speed does not...". That my friend, is a clutch problem. It can slip because it's worn out, out of adjustment, or contaminated (glazed) because of wrong oil (to repeat ourselves). The slipping can happen in one gear also (Do a Google search "Clutch slipping in high gear") but that is usually a precurser to it failing in all gears. I think you end up putting more torque on the clutch in higher gears and that's why it often appears there first (an opinion).

You have asked us for some help and we have asked you for some info. If you are going to compare our suggestions to what your mechanic is stating without providing the info then....... Once again, how much freeplay do you have in the clutch cable????? What oil are you using in the engine???? Can you take a picture showing the amount of freeplay in the cable attachment point at the lever and a picture of the belcrank attached to the engine to verify it's in the correct position. Oh, by the way, like Turbo, I'm a licensed automotive mechanic with a diesel endorsement. I also have a heavy equipment license and have been in the trade for over 50 years.

Wow guys, I am not doubting your knowledge for a second! If I for any reason gave you that feeling, I apologize! Just trying to learn and understand what could be going on and creating a plan from it. I get information from more than one side, so it can be confusing.

As I am also by no means a mechanic, I have to ask questions and try to determine what to do. I will try to make pictures of what you suggested!
 
Hans, sorry for coming across a bit harsh... We ask questions and make suggestions to help diagnose a problem from afar and instead of answers we often get more questions (implied doubts) which leads to frustration. Personally, I thought your mechanic was questioning us and our skill level because of your statement, quote; "So it couldn't be oil or adjustment related if I understand the mechanics a bit, or could it?". As I look back at your statement, I can see you are just trying to learn and you're getting some conflicting info that you are trying to resolve. No problem bro...

Here are a couple of pictures taken sometime ago by Warp9 that I've copied showing what we are looking for at the clutch lever.

Outer cable pushed in to the clutch lever adjuster...

Outer clutch cable pulled slightly showing the desired freeplay required. This amount of freeplay will keep the lifter shaft away from the pressure plate ensuring your clutch is fully engaged when the clutch is released.

No worries whatsoever. That's the hard part of communicating only by writing. So much is lost without all things non-verbal.
Thanks so much for the pictures and explanation, will check that stuff once I am home tomorrow.
 
Well it's Sunday morning and I am more relaxed and 80 years old and seems like I have answered a million questions so my temperature goes up when it seems like some one douths my guessing and also questions whether it's worth taking a few pictures.
So I am a little blunt or a bit short fused but I am who I am and not going to say I'm sorry. It seems to me the mechanic could have got it to slip in another gear but maybe he did not want to walk home. Lol
I have seen a few clutch cables way off from normal one in my shop was way off and hard to pull that one had a bad clutch lifter and shaft and there is a thread with pictures where the cables where way off and slipping.
 
It's been too busy, but I managed to make some time and check. I have the feeling this was set awfully tight, as I can hardly pull it back to create the space seen in the pictures you sent. There is also absolutely no slack on the clutch lever, so I think this might be an issue. This is mine:
