Modrod,

I decided not to fit this oil cooler kit as I thought that the oil pipes could easily get caught up in branches or rocks when off road, I use Motul 7100 and so far I have had no indication of overheated oil.

BTW I have done a few mods to my XTZ, the main ones are :-

BBR 150cc kit with performance Camshaft
Protork Exhaust
Mikuni TM24
Programable Ingtech CDI, set up by yours trully
YZ250 46 mm forks, YZ 250 front wheel and brakes.
TTR125 Aluminum swing arm, shocker and pro link

I am running Kenda 778 tyres front and rear.

It has turned into a really nice bike, of course it is short on power but next summer I am planning to do a 194cc, 4 valve conversion using aftermarket parts for a Yamaha Zuma. That should get wake up the old girl.
