Hello I'm Leon from the Netherlands and new here on the forum.
I did some maintenance on my R80 and when I checked and correct the timing of my ignition I've noticed that the ignition hall sensor is turned maximum counter clockwise. Actually he has to go a little further for a 100% correct timing

I did this with around 900rpm. Is this normal or could there be a reason that the hall sensor is in this position?
What gspd is saying is that timing at speed is more important than timing at idle. Make sure it's right for the conditions that could actually damage the engine if timing is wrong and let the idle timing fall where it may.
Call me Mel. Some years ago- never mind how long precisely- having little or no money in my purse, and nothing particular to interest me at home, I thought I would ride about a little and see the other parts of the world.
Ok I do understand,
I did the check with 3000rpm for the "Z" mark and it looks like the same by idle "S" mark. It needs a bit more adjustment to be spot on.
Is the ignition system on the bike completely original. Some aftermarket systems institute a delay in the impulse (for various reasons)?
Have you ever checked the timing (I mean personally) and been able to set it up correctly?
Has any work been done on the engine (or the bean can) that could affect the timing?
On the face of it, the problem you are experiencing can only be due to the engine or to the sensor unit. The only adjustment is the position of the sensor unit.
Personally, I would like to try another sensor unit... not because I think a fault in that unit is likely but because it's the easiest thing to eliminate.
That being eliminated, I agree with GSPD that the probable cause is likely to be a worn timing chain. Something I wouldn't want to ignore for too long because, if it's that far out, the chain is very worn and eventual complete failure can't be ruled out.
