Yes, it goes back to the filter and yes, it makes more sense than waiting another month or so!
I'm not good with Math, so I've measured the fin area and got 145x 55 for OEM and 185 x 61 for this one that has the wrong ports.
I'm coming up with an incredible 41.5 percent increase and I think I may have missed read my scribbling

So assuming the Math is correct as it has not been challenged! 
I drilled and Tapped the Ports to 12mm x 1.25 and ordered a new one just in case I make a mess of it,
Which not that surprisingly did occur forcing me to cut one thread 1/4 NPT ( more contamination ) which has also committed it to being fitted in one specific orientation.
Lucky I ordered the second Cooler By the time I get hose and now a NPT fitting it will be half way here, last one took about 2 and a half weeks

Fin area is 185x105. That's a whopping 140% increase!
I guess now I have to find a way to WARM the engine...
PS. Just checked the connection, I got lucky and the sent they right M12 one!

Bracket for Oil Cooler reversed. I did straighten it after !
Adaptor Bracket from 3mm Ali.
Frame Weight reduction! to allow clearance for the lower fitting.
Cooler is high enough to enable the Inspection plug to be removed for Timing Marks to be observed.
Okay I realize that the Angle is not optimal, but with 40% extra area and the extra Oil capacity I should still be in front.
Now to finish off the Hoses and see how neat they can be done!

works for me ! this is the description, "M12 P1.25 M12 * 1.25 M12 x 1.25 Banjo bolt brake Adapter adaptor tpfe ptfe brake hose fitting"
then you need Hose ends,
They are AN ( Army Navy ) fittings and it is AN-6 Hose I am using.
You need 2 for the Engine and 2 for the cooler, easy way is 14mm banjo hose ends at the engine and 1 of 12mm banjo hose end at the cooler at the top and a straight AN-6 hose end going to the bottom of the cooler where you need a 12mmx1.25 to AN6 fitting, comes with an O ring.

1 M of hose is enough for two bikes, or a few attempts at making hoses etc and probably the minimum anyhow
