Hi,
I am rebuilding my FE400 because of the chronic top end problems and other issues after 9 months I got it second hand. Actually I have not been able to drive it for long due to recurring mechanical problems. Recently I take the cylinder head off and the picture was depressing. You can shake the piston in its sleeve almost 0.8mm(I didn't make measurements yet) in each directions.
I think this is due to stuck oil pump because of shavings through the oil line before filter. There was no oil screen on the oil drain plug when I got it. Previous owner was a complete idiot. :evil: I had fixed the oil pump after I reliazed it in weeks since I got it but it was too late..Thus the story ended up with blown engine long before I got it I think. I still wonder how it held and still was running nice. To cut it short, I fortunately managed to find a parted out FC470 auction on ebay and got 100mm piston sleeve BV head and valve cover with rockers for BV head. So I had to convert it to 470 but I don't have the crank and counter balancer for 470. I think I can reuse my crank and balancer although there is slight difference as Taffy has mentioned before on the forum. My question is whether it is possible or not? I will change the bush on little end. I wish big end is fine at least..
