The yamaha cylinders come stock with a Nickisil coating which is super hard and
I didn't realize the cylinder was nickisil. Can anyone else verify that? Reason I am asking is that I am about to install a new piston. The cylinder has no damage or noticable wear, and relatively low miles on it.
Should I do a crosshatch with the hone? If it is really nickisil, that probably isn't a good idea. If it isn't nickisil, I would think the crosshatch is necessary to ensure that the rings seat properly.
Please advise! Anyone? Thanks in advance!
