oil cooler

Postby L2R » Wed Jul 13, 2011 4:09 pm

Someone on another forum asked about adding wings to get more air to the radiator. Can't say it would or wouldn't help but....

I have an oil cooler on my truck. I believe it helps in summer heat and I got a 100,000 warranty on my truck tranny on the condition a cooler was added. Seems they believe in them too.

So........I googled motorcycle oil cooler and WOW they want a bundle for them. 300 to 550 bucks. My truck oil cooler choices were small, 55 dollars or large 80 dollars............installed.

I went to JC whitney, the have a 3/4 x 6 x 17 oil cooler. I don't know these engines-is there place to add this?
I would think with 2 up and a trailer it would be beneficial.

Any advise, ideas or opinions appreciated.

Love 2 Ride

adding an oil cooler to a wing will drop the engine temp too much

I have ridden 2 up with a trailer with the 1000, 1100 and the 1500. No problems with either. I don't think it would be necessary.

My '91 Wing has pulled a trailer for (mmmmaybe) 12,000 miles now. Varying from 350# to 1250# without the need of an oil cooler. I'd say you don't need it.
Water temps were always normal except in hot weather (+88-ish) the fan did come on more often but never constant.
I suggest "IF" you're riding in high temps and pulling a trailer change to the next heavier oil weight. Stock Wing oil is 10w40 so going up to 10w50 will work. I have tried 20w50 and found it is to thick. I got uncomforting metal sounds from the lower end of the motor. Went back to 10w40 and all is normal.

A non-Wing note. I pulled a 1000# trailer cross country behind my Yamaha 1977 XS1100 (air cooled) and only incident was pinging in the mountains on hard throttle.

All in all, most motorcycles are designed to keep cool in nearly all harsh conditions. It's the really extreme conditions one needs to worry about. I'd say my conditions are on the extreme side and didn't need an oil cooler.

Hope this info helps. :)
P.S. IF you still think you need one find the smallest one possible. Less area for rocks to hit and it won't cool the oil too much. Also, in my opinion, it don't need to be in direct air flow. It's just supplemental to an already well (some say overly) designed machine.

Know its new taste and be loyal, you'll know when to change that oil.
Taste testing as the miles flow, souring as that acid grows.
And don't flirt with dirt or darkened oil, all the faster your engine will spoil.
