After going through the hassle of o-rings getting hard and leaking and changing this or that on a regular basis, I developed an o-ring replacement schedule that replaces them before they start leaking. to save money I took OEM parts to an industrial seal supply and had them matched up. I've been using the industrial parts for 40,000 miles and saving a to of money, and not having leaking o-rings.
I'm putting together an order for Viton o-rings for Tdub's next 48,000 miles as I'll be out of stock after the next service. I've found industrial Viton o-rings at least as durable as the Yamaha parts and significantly cheaper. Here's the "kits" I'm going to bag up for myself and the intervals T-dub needs them replaced to avoid leaks.
My maintenance intervals are:
2000 miles--change oil
4000 miles--change oil and filter, check valves
repeat
My o-ring replacement intervals are:
2000 miles--oil change kit
4000 miles--oil change kit, oil filter change kit
6000 miles--oil change kit
8000 miles--oil change kit, oil filter change kit, valve adjustment kit
repeat
Contents of kits:
1) Oil change kit:
Oil fill cap, oil drain plug. Every oil change.
2) Oil filter change kit (every other oil change):
Oil filter cover, shoulder bolt.
3) Valve adjustment kit (every other oil filter):
Rocker cover (2), large plug on side cover (1), small plug on side cover (1). Every other valve adjustment.
I've not had to replace any other o-rings, so I'm not messing with them.
I'll be putting each "kit" in a ziploc bag with an index card saying what it is. If anyone is interested, 50,000 miles worth of o-rings for the stated schedule will fit in a USPS Priority Mail Domestic Small Flat Rate Box that ships anywhere in the U. S. of A, FPO, and APO, for about $6. I think a USPS Priority Mail International Small Flat Rate Box ships most everywhere else for about $15.
I'll call Monday and get prices if anyone is interested.
