At my experience, the best matrial for bearings is a soft cast iron. Coz they have big sponge holes. It can keeps oil even they are dried. I'm used for crank shaft bearings without having any problems. And last longer. Otherwise, using cast aluminum ( i melt it from engine scrap)

awesome work!!! problem with this engine and kxf engine factory had error in manual for 12nm cam torque and it was supposed to be 9nm. stopped seizing cams when i dropped to 8-9nm and they later changed service manual because of error. i wish they came with removable/ replacable cam bearing like this

Ha I have recently done the same thing though I retained the bearing shells the same way as with crankshaft brearings, an interferance fit. the camshaft wasnt badly scored and polished up fine. When I made the bearing shells I held the two halfs in a four jaw chuck in the lathe, took a couple of goes before I had a succesful outcome but it worked cheers
for this video I suggest all people have motorcycle before you running the motorcycle You need to starting your engine atleast 5mnts to 10mnts to become up oil engine.

I can’t understand if the bearing, after being made on the lathe is then cut through the centre, then how is that a perfect circle? What am I missing? Thanks

One bearing is made of two pieces. It is cut and then milled in the cylinder head into a precise semicircle.

Just for inform. Don't used aluminum alloys for bearings. They will stick to cast iron, coz that metal didn't have sponge holes. Thats why all engine using cast aluminum. Rather than aluminum alloy, i suggests using cast iron or bronze ( copper phosphor) they wouldn't stick to cast iron (cam shaft)

@@PaulXchannel for sure! Bronze is self-lubricating and more resistant than aluminum. It is currently and widely used for these purposes, practically on all car engines. Being more resistant you can make these bushings thinner. I wonder why they don't use it on these heads, now I understand why these bikes don't last so long. To be precise there is a special bronze just for these purposes if I remember correctly. If you inquire around you will find confirmation.
