Big difference on chain, DID O ring chain or any good quality chain, the manual lists the number of links. In Ontario it is illegal to use a clip or master link on a highway / street bike, theory is people don,t know how to install clip link. When I say illegal, it won't pass safety.
I am on my original chain, 16000 KM, sprockets look like new.I use trip "B" for lubing the chain, when I hit 500 KM , time to lube, reset trip and start again. FYI I have the Kawasaki 16 tooth front, about .015 " clearance between chain and housing. I use Dupont chain saver or multi-purpose lubricant, available from Lowes around $6.
