Back again with a headscratcher. I noticed I had the typical rattle from cam-chain, and quickly ascertained that it must be the automatic tensioner. Ordered the manual one, installed it and tighten the chain up in the correct way.

Rattle was still there! Started searching for possible faults and found that the rattle goes away when clutch is not engaged, and when clutch is engaged the rattle comes back. It appears to go away as soon as RPM goes up, but there is a terrible rattle at low rpm and during cold start. The sounds originates from the right side of the engine (clutch side)

Anyone has any idea? Clutch housing?

Yeah I read that before posting, but I'm not sure if he had as much rattle as mine does. It sounds like something is about to go boom inside the engine. If this is for example an issue with the clutch bearing, discs, etc. I want to open the engine up and fix it.

Okay, so I still haven't figured out what the rattle is yet, so I made a video. Now, this is how it sounds when the engine is warm. When the engine is cold and is sputtering more it sounds like the engine is building a house inside the case, no joke.

We can conclude that I have freeplay somewhere, and the natural uneven idle of the engine makes the freeplay cause rattle sounds, but the question is where does it originate from?

Clutch bearing? Basket? Clutchdisks? Bad clutchsprings?

Solution:
Previous owner installed the clutch basket assembly the wrong way. It should go together in one specific way. If you install the baskets in the wrong orientation, the cogs will not lock up together, thus causing a clutch rattle.

Well done - good work narrowing the problem down to the clutch basket. :D
