The second is to find one of member TC's adapters, made for a short time a few years back. He was selling them here in the forums (around $25 - $30) and maybe someone has one of these. If I recall they also used a spin-on filter. At least one member plumbed in a thermal bypass unit so the engine oil would warm up quicker in colder conditions before being sent to the cooler.

    I would suggest that adding a cooler today will take some "cobbling together" as the original Yamaha lines are now over 40 years old and not reliable.

    How effective are the coolers? While anecdotes are around, testing that I once saw indicated the coolers dropped the oil temps by about 15 degrees F when the ambient temps were around 80 degrees F. Oil has come a long way since the 80's and a cooler may not be needed any longer. I lived in Arizona for a few years (2001 - 2003) and ran the XJ, pulling my trailer in many instances, and had no problems. I ran Rotella 10W-40 and changed oil and filter about every 3,000 miles.

    As many have stated, the XS11 engine will run for long periods of time if properly maintained. Adding an oil cooler sounds like a great idea but may have little practical value when using modern oils.

    There is a joke about Arizona I heard when I was there. A priest was trying to set up a church, and after a few years had to head back east to update the church elders. He was having a hard time establishing a congregation and the elders wanted to know why. The priest replied that residents in winter had already seen heaven and residents in the summer had already seen hell. The church could not compete...
    That's GOOD!

    And seriously...I'm grateful for the wisdom of experience. Thanks! Now "out of the heat and into the family room"...:-D

    I was in AZ not long ago and we grilled out when it was 100, I don't know how ya do it.​​​​
    THanks, lol-it's a matter of necessity...since I just moved here...unless I drive my car or truck.
    I tell you what, I was well aware of the thing that's called "wind chill factor". What I wasn't aware of is that there's a HOT AS HE** FACTOR...and the faster you go the hotter it feels.
    lmao
    holy cra* is THAT hot!
    I'm looking into cooling vests... and bedouin attire.

    Rats.
    Thanks for checking!

    I might mention I have 2 engines with no oil coolers on them and over 100K on them, no related issues. YMMV
    That would be nice-to see if one for sale, that is.
    It may very well be unnecessary. 21,000 on mine. Being shipped to me soon..God willing.

ID:	865266 It is an easy add on. There is an adapter for the oil filter that has in/out line fittings then use oil rated hose to plumb it. Neatly zip tie the hose and your done.

Maybe someone here has one to sell or you can check Ebay. I live in a very hot climate too and I don't run any coolers on my bikes, haven't had any issues. Your temperatures are probably a bit higher than mine though.
    THanks for the reply.
    I'd be looking for the/a complete setup -not a hadgepodge of pieces jumbled together. Sorry. That's just me. I'm not particularly mechanically inclined and have to read instructions. The guy I used to work for once took 3 boxes of parts and the disassembled cycle and put it all together-not a chance in hell I could do the same.
    Now of course I could do like guys who winterize their bikes and just park it for a few months. And I could still use it as a grocery scow 'cause the stores two miles away.
    Thanks Mr. Phil!
