Back in the day I had a kit from Serckspeed I seem to remember. Relied on a spacer plate with take off pipes between crankcase and oil fiter. Just googled them and it looks like they are more car orientated now with their products.

Seems Lockhart was a good name for coolers.
Here's a NOS kit (lots of pennies though ....):

Or if you can get an adaptor and hoses here is a cooler only:

Thanks all, I'll probably end up having to get the parts seperately, just thought it would be quicker to get a kit.

I know that most of the road bike kits for that era used the adaptor plate behind the oil filter but I think any dry sump race motors would use the return oil line to the oil tank to pass through an oil cooler.
Basically the return flow line would be diverted out of the engine to the cooler matrix, with the out flow from the cooler then going to the oil tank. This line is also vented to atmosphere as opposed to the road type running at full pressure that's used for the bearings.
If you went for this system you'd only need two lines made up to get to the cooler by using the existing end fittings from the honda return line plus the fittings to get into and out of the cooler.
Not sure what system is used on a genuine CR bike so maybe worth more research to identify.

Yes that's the system the original CR used, I'll move to that when I get a replica oil tank, but at around £500 it won't be any time soon, I'll probably go for an alloy fuel tank first, just took it for a very quick ride ahead of tomorrow's MOT and on first impressions I may be better working towards sorting the handling out before I do anything else! :-\
