Model information

[Marcad]

Hi all, new on here, Great resource. I have a 1981 GS650G which I would like to take off the road to clean and tidy up and to do that I'm looking at a GS650 Katana from 1983, my question is, this Kat has an oil cooler mounted at the top of the frame, I have seen Katana images with and without this oil cooler. My question, is the oil cooler OEM on a 650 Katana? and when did it become standard fitment?
Thank you in advance.
I think I have found the answer in the parts schematics, pays to look I suppose.

Between the parts manuals online, free factory Suzuki service manual downloads, and the archives here, just about any technical question you can think of has already been answered.

Hi There, oil coolers were fitted OEM on later models and in some markets on GS650G Katanas. Those fitted with the cooler also had a different sump-plate which had the in/out for the oil cooler and the oil pressure relief (part of the plate) was also a different configuration. Bolt pattern was the same.
