You are correct.The wear that causes elongation(wrongly referred to as "stretch"),occurs between the pins and bushes.This is taken care of by the factory internal lubrication held in by the O rings.
The rollers experience some wear on their inner surface when rotating on the outer surface of the bush.And the rollers and sprocket teeth wear due to contact between each other.These last two types of wear need to be lessened by external lubrication.This lubrication also keeps the O rings in good condition.
91k is the highest I have heard of. I have noticed that some bikes with auto oilers have chains which, in my opinion, have insufficient oil on them - they look dry. My guess is the oiler is wound down to stop splatter. My chain is kept wet and that means I need to wipe some splatter off after a decent ride. It will interesting to see how the chain wears on the busa.
Here for the ride.
how do you clean your chain, with kerosense? Do you wipe off the excess prolan after applying? I use prolan on just about every exposed metal surface but have yet to try on chain...
I am really interested in hearing more about your use of Prolan as chain lube. I am currently using the Yamalube product, but it leaves a fair amount of splatter everywhere (even after wiping off). I'm tempted to just try using wd40, but Prolan might be a better option. How many k's have you ridden with just prolan, and how often have you re-applied it?
I don't know anything about Prolan but don't go using WD40 on an O-ring chain..... apparently it dissolves the O-ring grease inside the chain.
If its any help to you, I use silkolene Chain Gel in a spray can.Its non fling and forms quite a stiff wax-like coating. I get it from Super cheap autos. they have quite a selection of synthetic and semi-synthetic chain lubes. Just make sure you read the label and, if it says O-ring safe then its good as gold.
The operative word there is "sealed".
If it gets in there you have other problems.
WD-40 themselves recommend it for o-ring chains.
I chopped up a chain well past it's use by date off my XR250 race bike and it'd only been lubed with WD-40 and there was still plenty of grease on the pins.
wd40 ftw!
Prolan works fantastic as a chain lube...so far. After trying several brands and getting tired of the goop build up and splatter, I cleaned the chain today and applied Prolan. After 30 ks of riding, no splatter, and the chain is still shiny with lube. I have been using Prolan on the bike, with no rust after a full year of getting blasted by Hokitika salt rain. I reckon Prolan is the best product out there for just about any metal protection. It works great on my firearms as well. GO PROLAN! Oh yeah, I also sell Prolan products in my store.....
