Reading the one thread where Jerry mentioned having to bore out the steel sleeve completely, I had a question. This cylinder has a chrome type bore. It's from around '85-6. I was told that it's a good one, that it revved quicker because of the coating. Grk made a comment that since not that many were produced it might not work. Good point. My experience with a Tecate and a kx electrofusion lined cyl it did rev faster.
But the question is could a aluminum sleeve be installed after boring out the steel sleeve on a Zilla cyl, port match to current specs then nikasil it? Would there be any benefit piston life or otherwise? Any insight?
Sure. But won't really gain anything. The steel sleeve is stronger and you can plate it to get the same slippery surface. The problem with zilla cylinders is the piston We covered this somewhere already. Have to see if I find it.
That piston thread had a lot info helping to understand what forces are working against it....
Thanks I was mistaken thinking the steel sleeve was the handicap.
It's was great just having to replace the piston assembly
