external oil filter on 78 KZ650 ?

wanting to use a remote oil filter on my kz650... any info is greatly appreciated.

I don't recall ever hearing of a remote filter set-up for the 650's/750's, I do vaguely remember hearing of one for the larger 900's/1000's.

Just curious, but why are you considering getting one for your bike?
If it's so more oil is in the system for cooling purposes, you could always simply get an oil cooler for your bike.
In fact, the oil pan and integrated oil cooler from any year of the GPz750's will work.
The oil pan is a direct bolt-on, and you'd just need to fab up a bracket to mount the oil cooler to the frame.
I have this same set-up on my '78 KZ650 and my '84 ZN700, and it does help in the frequent 100+ summer time temps we see hear in Calif. Plus it looks like Maw Kawi equipped my bikes with them.
