Niko, I am happy that you are having good results now, but please refrain from playing with the settings with your K-80 too much, factory told me after they cleaned your engine from what seemed extinguisher residue, they found your acceleration delay was set at 0, Dirk also forwarded an email of you asking about various adjustments that were unnecessary and detrimental to how the engine will run. Bottom line, if it runs good, leave it!

If your fitting is still intact, please put a drop of oil on the 3mm tubing, and it will slip right into the festo fitting. Without the oil, 3mm tubing is softer and difficult to have a good insertion.
