Vixion Block Or Jvt 57mm?

[Francisco N. Maristela]

yes vixion if 57mm for reliability setup/everyday use with spirited driving.Racers use JVT or steel bore plated with NIKASIL or chrome because you can shave the bottom or top of the block for high compression whereas Diasil can't be shaved because it is made of silicon and you won't get a clean shave causing leaks. for me, i am only eyeing at 57mm vixion or 62mm UMA for reliability setup retaining the same compression ratio so it would still be fuel efficient.

I have first hand experience shaving the deck/top and bottom part of Diasil cylinders and never encountered leaks even by just using threebond and no gaskets (for the bottom part only since the deck/top needs a gasket to make sure water doesn't leak out). I've tried it on my Mio MX 125. Shaving the deck of the cylinder is not recommended unless you know what you're doing. I had to manually finish off the shaving of the cylinder deck/top to make sure it is flat (using sand paper and a big flat glass from our garden table).

Even if the Diasil is hard, it's no match for the tungsten carbide tips my machinist use on his lathe.

Pa OT papz... is it ok to use jvt 57mm forged piston on vixion block? If this piston will fit to vixion block can we use OEM vixion rings instead of jvt rings? Thnx
