After riding uphill I stopped and laid my FR down. Starting it up again, a rattling sound... end of story.
...fact is the hydraulic Cam Chain tensioner or also called the Timing Chain tensioner of my Ktm Freeride 350 stopped its duty cycle causing the Cam to turn over one tooth. Luckily on tooth didn' t damage the Valves, so the got no hit from the cylinder and didn't bent or even break. That would a been a disaster.

This is how the Original KTM hydraulic Cam Chain tensioner looks like:
Normally oil pressure is even too High causing too much wear of the chain.
Testing my hydraulic Cam Chain tensioner on a flat table, pressing it down it remained blocked. It should not happen after only 70 hours.
Conclusion: I will grab a new mechanic Cam Chain tensioner from Mito Racing and get rid of any trouble and noises coming from my engine. Adjusting the new Mito Racing Cam Chain tensioner is pretty simple.
I have put a little HowTo and review here.
