No power loss, valves have been adjusted and chain was on tight. Have no idea what it could be. Happens only at high RPMs. Has anyone encountered the same issue or has any idea what it is ? My final guess would be the cam tensioner due to failure of the hydraulic stock tensioner at high rpms ? ? What do you guys think ? Really hoping its not the engine.

Cam chain tensioner is not hydraulic and prolly not the problem.

I would suspect clutch needed adjustment and is slipping. It may be to late for adjustment and needs replacement.
