Hey guys I'm wanting to install an oil cooler unto my GS550. I've been following the tutorial online for making my adapter. Im headed to my salvage shop in the morning to find a cooler. Being a low pressure oiling system does size really matter for the cooler or will anything work?

The bigger the better, and coolers which have several horizontal 'rows', as opposed to more basic types where the one tube just snakes back and forth through the cooling fins, are more efficient. -

Low pressure but high volume. Be sure that you use a cooler with enough flow capacity.Originally posted by nate25tenn View PostComment

He needs an oil cooler because... well, to paraphrase Cassius Ceramix from 'Asterix and the Big Fight'...
"Right then! We're going to build an aqueduct!"
"An aqueduct? But Chief Cassius Ceramix, the river flows right through our village and crops and fields..."
"Well, we'll divert the course of the river! Aqueducts are more Roman!"
Ergo, oil coolers are more Suzuki.

They are? How so? Putting one on my 750 It's not recommended, mine being a friction bearing 750. Again my question is, why does he need an oil cooler, just curious is all.Originally posted by tfb View PostHe needs an oil cooler because... well, to paraphrase Cassius Ceramix from 'Asterix and the Big Fight'...

The best reason is he is bored and needs something to do, and there is a fair chance he can get it installed without hurting anything.Originally posted by mrbill5491 View PostComment

Just about every air cooled Japanese 4-cylinder made since 1983 has had an oil cooler. Simple fact is air cooled bikes run hotter than hades in the summer. The problem with adding a cooler is you get pressure loss in the system which is not good, and it's difficult to build a thermostat into the system so the system doesn't come up to temperature unless you ride the bike for a while when it's cold outside.Ed
To measure is to know.

As long as I don't push her 'till she's warmed up, is there any problem running cold?Originally posted by Nessism View Post
I start with full choke, almost immediately turn the choke off and ride (relatively) slowly away. Even in warm weather, it can be almost a dozen highway miles before the oil temp needle even moves off bottom.
Any real need for me to install a thermostat or block off the cooler this winter? Before the cooler, oil temps got too high.1982 GS1100E V&H "SS" exhaust, APE pods, 1150 oil cooler, 140 speedo, 99.3 rear wheel HP, black engine, '83 red

Lockhart used to make a nice oil cooler thermostat that bypassed the cooled until the oil was warm. I ran one on my Commando for years. Later, they moved it into the oil cooler itself. Other companies are still making them.
If you get a used cooler / thermostat, be sure to flush it clean.sigpic Too old, too many bikes, too many cars, too many things

I had a gently used 1150 cooler installed. I wanted to 'keep it in the family.'
Bought from a site member, it came with a brand new 1150 filter cover.

Forgot i posted this. I don't need one but it can't hurt to have it. I machined my own adapter copying a tutorial on BassCliffs website for fun at work. Seemed like a good idea to me.Comment

I have a Lockhart 700 oil cooler with an external thermostat on my 1000ST. Pressure drop was never much of an issue as far as I can tell. I fill the sump with 4 quarts of oil to compensate for the cooler and the associated plumbing.Comment
