How To Modify Side Case For Oil Cooler...
« on: September 13, 2014, 09:17:14 PM »
There has been some discussion about oil coolers & how to plumb the cooler, etc.   Before I go any further, I am no expert on the subject & I'm only displaying pictures of one way to modify the side case. This side case came to me already modified. If someone knows of a better way to plumb a cooler, please post it up.

In picture #1, you can see the feed & return. You can also see the machine screw that has been used to intersect the internal oil passage.

In this next picture you will see where the set screw intersects & blocks the internal oil passage.

Here is the lower port. Drilled, tapped & fitted with an elbow.

I have seen one other FT Ascot side case that has been modified for an oil cooler. Instead of using a machine screw to block the oil passage, he used some JB Weld poured into the area where my finger is pointing. He made sure the area was clean & oil free before he applied the JB Weld.

There you have what is probably the most common way to tap into the system. Like I said, if someone knows of a better method, please let us know.

Thanks
J.

I wouldn't take this side case as the gospel on how to plumb a cooler. There is some debate on the Yahoo users group. I found another side case yesterday that had been modified also. Forgot that I even had it. It was plumbed for a Lockhart cooler & is done the same way except they used an epoxy like substance to fill the oil port to block it. So far, I have seen 3 of these covers modified the same way. It may not be the best flow of oil for the engine, but it seems to be the most common way to route the oil flow to the cooler & back.

I'm open to suggestion. I would like to learn the "best" way to plumb a cooler.

Thanks
J.

Hey J.
I have heard of people plumbing the return line into the valve cover to help with the poor delivery to the head that the bike has. Have you talked to anyone that has actually do e this?

I've heard of that being done also. Have not seen any examples though.

Ended up finding some xr500 guys that have ran it to the valve cover.
