Hi all,
I replaced my oil metering pump today. On the removed unit, there was NO line going to the chain. No big deal. It was all sealed up, no problem. I'm just wondering if this is a common "modification"? I wish I could tell what kind of chain I had. Maybe an O ring chain? How can one tell? I just want to know what to lubricate it with. My CBX has an O ring chain and I use "Chain Wax". The RE-5 chain seems oily, grimy, and dirty. Any advice on how to clean it and how to lubricate it and with what?
Thanks as usual!

The oil line to the chain was discontinued when the switch was made to an o-ring chain, so the service bulletin update was to blank of the outlet with a bolt and sealing washer.
For any modern chain you should use the new X ring type and select one suited for a sport bike of 750 cc or larger, this will give you a tensile value way beyond what the RE5 can deliver.
To clean such an x ring chain you should wash it with a brush and kerosene about every 500 miles of use, dry it off and apply a good chain lube. Do NOT pressure wash it as this sends moisture into and beyond the seals and will ruin the joints after a while.
I like the motocross specific types of chain lubes best since they are more durable, considering the conditions off road bikes have to deal with.
Chain waxes are considered 'dry lubes' and are not really suitable in my opinion simply because the dry metal to metal contact prematurely wears the components.

Dave,
In '75 chain oilers were used on the early bikes from a prot on the metering pump.
By '76, Suzuki deleted the line and capped the port at the factory.
This is why some bikes are equipped with them and some are not.
There may have even been a service bulliten directing dealers to "cap off" the metering pump chain oiler... I would have to look at my notes.
I have found chain wax to be an outstanding product on almost any modern chain... In my opinion you need to wax regularly, yet if done, I find that wear and stretch is negligible.
I also prefer chain wax as it is not near as messy as the oils or motorcycle lubes.
Best,
Jess

How do you close the the oil line to the chain ? Does it have any effect on the line to the carb ?

As Suzsmokeyallan said "The oil line to the chain was discontinued when the switch was made to an o-ring chain, so the service bulletin update was to blank of the outlet with a bolt and sealing washer. "
The new pump I got from Sam had this small bolt in place. That's what started my question.
Hopefully it will be warm enough today in the Cincinnati area today for me to test the pump. I have not tracked down some sort of way to measure the flow at a given RPM for a given time. I'll figure something.
Plus I have to test my newly rebuilt front brakes.
Plus I have to see if I have the cooling system all sealed up.

Dave,
Take a syringe (big one)... Use cable ties to tie to your crash bar...
Fill it with oil... Take a hose from end of syringe to input on metering pump.
Start bike... Run for 5 minutes at 2000 rpm... Do a liitle math on what oil is missing from your syringe.
There you go!
Best,
Jess
