where do you go for fittings?
i have a 1100gpz oil cooler and need fittings for a 1000J engine relitively cheap, anyone ever modify their J fittings to run a cooler?

Have you tried looking at www.americanclassix.com ?
www.americanclassix.com/kawa_improvements.html Look about 1/3 down the page. If you don't want to spend that kind of money, maybe you can atleast see what the difference is to a stock pressure sending unit and mod yours. Good luck!

My suggestion:
Switch to Mobil1 15w-50 and don't worry about the oil temp.

Find a used, stock, oil cooler bypass from an early model GPz1100 or 1000R; it will fit. I will post a pic. This is a stock unit for an '81 GPz1100(modified a little):lol: and will fit "J" model cases.

StreetfighterKz is right-on. Check the pics; the engine oil comes up and out of the left side from the pump, travels through the cooler and then back into the main oil galley through the right side. Once running/riding, the engine will maintain an overall relative flow rate and pressure.

If you have flow, you are bypassing a section of the lubrication system. Simple physics.
When you factor in the fact that you only have a 3 psi oil system, you do not have any flow to spare.

BUT, why would the factory fit the oil cooler stock on my '84 GPZ if it's so risky? I am the original owner and I see no compromise in the oiling system by having it. It certainly isn't a marketing ploy. It's bigger displacement warrants it. As they increased displacement and compression, old suberbike racers and drag bikes had even bigger radiators. The PSI was still maintained to the rollers. I never heard of the longevity being cut by using a cooler in a big block KZ.
If you increase the displacement on your cop bike and sat on A1A, you would understand why your argument is dead.

Not being familiar with the GPZ engine I have to ask, what else did they do to your GPZ to accommodate the oil cooler? Higher pressure/more capacity pump? Change the oil path?Your logic is convincing. I understand the lower oil pressure difference of the big block roller bearing motors. I use Mobil 1 too.

I am certain they did not create a parallel-path system as the KZ oil cooler does.
I am well aware of the toll that punching out a kz engine has on its thermal rejection. Way back when, I had a KZ900 punched and pushed as a drag bike that used to win more than its share of races in the late 70's at ATCO speedway and Philly's infamous Front Street on occasion. I am a lot older and just a little wiser now than to try to break 150 mph in a quarter mile leaning head first.

The pump will still push the same pressure no matter if you have a cooler or not. It's also going the same route, just up throught he oil cooler and back down to where it would go anyway.
Then what induces the flow. There has to be a resistance between the two points that you connect the oil cooler to induce flow. That resistance is the system or at least part of the system that you are supposed to be lubricating.
If you were not bypassing at least part of the system you could not get any flow through the cooler. It is a poor design.
