Cast Iron Barrel Allright?

[1980z50j]

i was thinking of getting an 85cc big bore kit for my z50j. Would onee with a cast iron barrel be ok? i get everything with kit the ( piston , rings , pins , gasket kit ).... i can get the kit for $150 good price?

cast iron is the way to go

no dissimilar metals expanding n contracting to worry about like the alloy cylinders...

bit extra weight...who cares?

make sure the kit youre getting is meant for what you have....hondas good. china is a curse...grrr...
