Hello all,
Started digging into my GS after I noticed the bike had someoverheating problems and after tinkering around with things I want to replacemy old oil cooler and also the lines. The oil cooler is the original, and it works but after restoring thebike I think a newer one will add to the look, as for the lines one of them isleaking and I want to get some new SS oil cooler lines on their.
Does anyone know where to buy bolt on Lines or what sizelines are on these bikes and second does anyone sell a complete bolt on kit??
The OEM ones are discontinued
any info is appreciated.
 
You are mistaken. Your bike did not come from Suzuki with an oil cooler installed. There are no "OEM" oil coolers for a 1980 GS750.

You might want to post some photos of your bike and the cooler and lines. Most likely someone can ID what you have and provide some suggestions.
 
Probably either a Derale or Lockhart cooler. Take your fittings and lines to a local auto performance parts shop and have them put a set of lines together for you. If you prefer to do it yourself they can sell you the parts to build your own lines
 
You are 100% correct, the research I did leads me to believe the original owner put on a Derale oil cooler on it with some nice SS lines. IfI can get a new Oil cooler kit that just bolts on I will be more than happy to do it, or if I can just get the right lines with connectors ill be a happy camper too.

Will try to get better pics tn

Oil coolers are NOT recommended for your bike nor the 81 and 82 models. These bikes have friction main bearings not roller bearings, thus requiring higher oil pressures to feed the bearing surface. An oil cooler could rob enough pressure from the system to cause some serious bearing damage. IMO lose the oil cooler, you don't need it. Just use a good high grade oil whether it's diesel or a brand of sync oil. I ride my bike in the Southwest desert heat and have had no problems.
