So I got my bike back from the workshop yesterday.

The problem appeared to be a job totally messed up by previous mechanic. It was a set of problems joining together to create this totally unpredictable behavior and mixed symptoms of both lean and rich mixture.

The sliders were sleeved properly, but the needles were not inserted deep enough and moved freely inside sliders. Therefore they randomly opened and closed fuel supply, which was the reason for huge hesitation.

The second thing is that though the jets were 112, the needles were N60D, left from the previous, restricted setup. Unfortunately I don't know what jets were in restricted version since I have never seen them.

The third problem was that mechanic inserted air filter the wrong way- it wasn't filtering at all, cause it was placed longitudinal instead of transversal.

Last problem was that the carburators were not screwed up properly, and air entered behind the throttle.

No I'm having newer setup, with 95 and 92 jets. Everything is tightened as supposed to and tuned properly. Geeez, what a difference! The bike now flies compared to what it has been before. It easily reaches 10.000rpm under acceleration (I know it's pointless, but wanted to check it).

So, I should kill my previous mechanic, but I'm so happy that my KLE is now running fine, that I will just ignore him.

Thanks for all thoughts in this thread!
