After some minor difficulties, I had the tming of the camshaft slightly wrong the first time, I managed to change the timing chain. I also installed new pushrodtubes and gaskets, so now it stopped leaking oil. I set the timing today and took it for a testride. It runs great!! It sounds so much better (less metallic, warmer) and the throttleresponse is a lot better too, so I'm a happy man.
Other things I have done: Instaleld new velocitystacks (bought at IKEA) and removed the exhasutwrap and painted the exhaust.
