Hello!
I am writing from Estonia
As there are not many Hayabusas in Estonia, I thought I´ll try my luck here.
Bought myself a Hayabusa very cheaply. (Previously I had seen Hayabusa only from pictures, so lack of experience here...) Previous owner has removed engine and cylinders from engine. So I havent heard/seen it run. But I think life should be interesting. Previous owner told that he started to repair bike, because he thought that there was power loss, and when he opened engine, he saw that ewhaust valves vere dirty and he thought there was this problem but no smoking engine and no extra noises.... Good strory!
First I saw that two conrods were moving on the crank ca 1mm, so I replaced crank and rods and bearings. But I havent realize what has happened there... I think that engine has worked without oil, but I cant figure out where did the oil go... There was no leakeges. So I was reading this forum and started thinking about oil rings. I measured oil ring groove width (as below shown) and I got 1.90mm So I should replace them. Also I should replace exhaust valves, because they are burned and look like there are somekind of wormholes in them.
My question nr 1 is: What do you guys think, is it possible that this engine burned all oil, and previous owner wasnt check oil level and in ended like I described? I mean is it possible that engine is burning so much oil so fast?
Question no 2. I am changing all piston/oil rings and valves, also crank and conrods and conrod bearings. Is there anything else I should do as my engine is opened up right now?
