What is the best way to cool a 400EX engine more?
Will ceramic coding the engine help? Im really after something else.

I posted a few months ago looking for a larger oil cooler. I still think it would be the hot ticket, other than the Pigrys Oil Tank... So far, I am happy I switched to Mobil1 automotive oil. Valve train is much quieter now when the motor gets hot. It is my first time to use a synthetic in anything I have owned.

I seen in the back of my ditwheels that you can get a larger oil radiator. It costs almost 500 so i would go with other stuff first.

pingry over sized oil tank will cool it down alot it costs like 300$ i think...

The pingry tank probably would work good for a stock motor. It got mine back to about stock temp...

I saw the add in dirtwheels too. It pays to read every single word in it. Here are the exact words:

Cool your engine down! Make more horsepower! Add more life with a DTZ oil cooler kit. Thirteen row extra capacity oil cooler, lines and mounting hardware. $475.00 DTZ ATV (602) 769-6164


It wouldn't be to much trouble to call and find ut more about it. I wonder if it will let you run 250r air scoops.

you could get some way to get more air to the stock cooler. i imagine that would work halfway decent.

Pingry's extra capacity oil tanks are only $274 you can go to there web site and check it out at www.ppdracing.com

Curtis sparks recommends running higher octane fuel to keep the motor cooler,,go out to ********.com and read the questions emailed to him and his response's to them,,pretty good stuff.
But a larger oil tank would help matters I'm sure,,i just don't know if I wanna loose my arm to pay for one..

Sometimes I just put Ice cubes in my oil tank to keep mine cool..:huh

Hey honda guy, this is rebelblaster14 from extreme dirt bike and atv.This place will anwser all most any question you can ever need to know about your EX.

If you take a few measurements & have a m/c salvage yard in your area, go look at old import street bikes with oil coolers.
You can usually find one that will fit in the frame that is 2 to 3 time larger for around $30 to $40. then I just took the lines off the stock 400 & the line ends of the junkyard cooler down to an automotive hose maker & for $25 he made me new ends to match.
3 time the surface area & oil capacity for about 3 hours worth of looking & installing, & only spent $75 including oil.
Of course it only works if you have a yard to looking thru.
