I just use spit.

Don't use MOM spit it will take the chrome off your chain.

What sort of mileage do you see from your chains?

Some food for thought from a chain expert:

Chain wear occurs from Pin Elongation. This is when your Pin gains additional clearance within the Sidebars. Take a worn chain and measure a 120 link new chain vs worn chain.

Now, considering the vast amounts of chain types we have (X-ring, O-ring, standard) they all have different wear rates. This is of course due to the different protections in place to prevent Pin to Sidebar wear. Also, we have numerous types of Sidebar material that affects wear since this is the portion of the chain that actually wears.

So, different chain types will have different wear rates.

A O-ring, X-ring chain needs nothing more than for you to keep the X or O-ring cleaned and protected from cracking. Additional lubricant will only cling dirt and grit to the bar and promote wear into the X or O-ring. Cracking or wear to the X or O-ring will allow dirt and grit into the protected area and promote wear.

Clear as mud eh?
Btw: I have a driveshaft...

Dustin, im not one to take note of mileage but i get plenty. My personal opinion is the lube can get out as easily as it can get in. The high ridges that wear into the guides and slippers are what creates the most wear.

Any rough idea? 25,000 km? 50,000? 100,000?

Just curious
