Upside down head cooler

[Lachie04]

Hello Chaps,

Debating a question in my mind 

So I have a head cooler mounted as such

 

But to make room for headlight and brackets questioning if mounting it ∩dsᴉpǝ poʍu would work and give me more room.

I used to have it on the back but trying to keep the tail clean now  and not anywhere else which would work

I'm concerned it would drain back to the case each time  and then possibility of air blockage.

While the main cooler can be mount, fittings down, don't think you can do it with these. Closest I've seen to upside down is the one @Dezza is building which is rather flatish.

 

Any thoughts

I had the same worries, the bottom one is my head cooler, and when i took the pipes off there was no oil in the hose going up to the head!!, so i thought there would be no supply to the cams on start up..

so i took the plugs out and wound it over ,with the pipe to the rocker box disconnected at the head, to see how long before there was any oil..

 

I pushed the tit and oil came out almost imediately and lots of it.. And that using the starter motor which turns at a much lower speed that when the engine starts..

So im not worried anymore,,

 

dissconnect the pipe and try it..

The oil coolers are connected to the low pressure oil circuit and are not for oil supply to bearings ect so will have  no affect if it drains back to the sump . Just have to remember this when checking oil level .

Here you go, shows the oil coming into the back of the cam cover and draining down through the head cooling it.

As said, it's cooling circuit side and no engine needs cooling from a cold start - 10 or 15 seconds ain't going to hurt anything!

Thanks for the comments 

My concern was on the air locking side really  and if it were to happen from time to time while oil would still flow it would be ineffective  car guys have lots of comments about it

Any who Merry crimbo

You wont get airlocks. It's a positive pressure pump that will force air out, not like water pump which just gives flow.

My head cooler is mounted horizontally in the seat unit, which has a big hole in the top. The idea is that the pocket of still air under the seat will rise up through the cooler due to air moving across the top of the seat unit. Mounting a cooler in this way at the front of the bike is thus not going to work very well.

Head cooler on my track bike is mounted upside down and haven't had any issues
