New purchase, beginning of the learning curve. I’ve notice oil on the finned exhaust nut. Dismantled exhaust today. There was quite a bit of oil in the muffler, also in and around valve guide and valve steam in the exhaust channel. I would suspect worn out valve guide but since I am not familiar with the design perhaps there might be something else.
There is no blue smoke so it’s rather not oil form within pistons and there is no leak from valve rockerbox cover.
It’s happening only on right cylinder, left seems fine. Compression is exactly same on both cold and hot.
Please share your ideas.
Best regards
Jakub
