Piston rings ?
Posted: Wed Sep 17, 2008 7:12 pm
I have just bought some Nippon NPR rings for a Z900, the top compression ring has no marking on it to show which way up to install.Has anybody fitted these rings and will it matter as all other rings that I have used on other bikes normaly is marked in some way ( the second ring has an N etched on the top face). Any advice will be apriciated as the bike smokes like a wood burner at the moment on start up but mostly clears to a mild dark cloud after a couple of miles.[/b]
