Thanks to mat, i reliased i had the pre mix oil adjust set too high/rich. I've adjusted it and went for a spin. It's a lot better, but i was wondering what damage could too much oil cause.

Now i'm believe that the 150 has a catilic converter in the exhaust pipe. Would it have damage it with too much oil?

Another thing could be that the rings have had to cope with so much oil that they may be gummed up.

I will buy a tyga exhaust for it very soon, but i just wanted your opions on this matter. I've done about 400klms since the rebuild with excess oil in pre mix.

Your thoughts?
