Things didn't go as planned. I assembled the bottom end and as soon as I torqued it to specs the engine seized. Instead of trying to find the reason myself I took the whole engine to Pekka. He has all the right tools and skills to find all problems and so he did. The cam bore in the case was too small and flywheel side bearing was conical. Also the cam needed some clearancing between the lobes to clear connecting rods. After a week I got the engine back and now it spins easy. Excellent work by Pekka but what else can you expect?
Oh yes and if that wasn't enough also one of the conrods was defect. The thread was broken and there was no way of using it. Well, better to find it out now and not when the tachometer hits 8000 rpm. Thanks to Sami from our garage I got new set of rods in an instant. Also thanks to Aircooled's Tomppa who sent me a new set of rods as warranty. Great service.
