Yeah, remove the thermostat keep it simple. My Remos GX has a cockpit panel control that opens and closes a door in front of the oil cooler so temps can be manually controlled for a fast warm up and adjustment if needed.
Thx Garret,
I was thinking to install a butterfly valve like your talking about.
There is a 3inch duct to the oil cooler.
Looks like a perfect spot to put that butterfly valve with a hand actuated choke cable...
All the lines were perfect including the suction pipe the tank.
There was one bend from the thermostat that was a 270 degree 7 inch circle with 1/2 inch pipe. It didn't look kinked, but it did look like it may have been restricting alittle.

I'm expecting the oil will be cooler since I'm removing it, but was thinking to use a vavle like Garrett was explaining.
The thermostat was causing a tight bent, might be nothing, but not ideal.
When I took the thermostat off, it was open from bottom right to bottom left. Shouldn't this be open from bottomrom right to top right when cold?
In the pic, the bottom right goes to the tank and bottom left goes to top of cooler.
Shouldn't the bottom left go to the bottom of the cooler?
Seems like it's hooked up wrong.
And all my pipe is 1/2 inch.
Could any of this be the issue?
I'm going to go from tank to bottom of cooler then to pump.
I have the new style mushroom valve, spring and bolt.
Should I install them all while I have it apart or wait to see if the bend or thermostat was the issue?
The video on here said to do the mushroom only if the ball had signs of wear.
Thank for the help

I sent pic of oil cooler air flow door to your email. My Mac Book has some issue with getting pics on this forum. Make sure that hose is rated for high temp oil flow under suction or just get the correct hose.
Was thinking a butterfly would be the best, but yours is a good idea also
I'll have to see which one will fit better.
All the hose says is 1/2 on one side and 98891 on the other. When I Google that, it comes up with mil-6000 hose.
So I think I'm good.
The person that did the 5yr rubber in October is a fully certified rotax mechanic so I'm hoping he would know the right stuff.

You might find that the Thermostat is Open to all 4 ports when it is cold.
The Oil will take the path of least resistance and most of it will enter in the bottom Right and take the shortcut to the Top Right and back out.
A small portion of the oil will still pass through the Oil Radiator even when cold.
When HOT, the thermostat element closed the Crossover path in the middle of the thermostat forcing all the Oil to pass through the Radiator.
It is a simple mechanism and not as sophisticated as many imagine.
The design is at least Fail-Safe.
If it were to fail either OPEN or CLOSED, Oil will always get through and at least some cooling will always take place.

I would tend to agree that the Cooler is plumbed backwards.
The Oil should come OUT of the cooler at the Most Upper fitting.
This assures that any air bubbles in the Oil keep moving
