aftermarket fan

[400exmxracer]

I bought a spal 5.5" fan the other day for an aftermarket/bigger oil cooler on my 400ex. I just want to make sure it will work and not ruin my stock stator

[on the rocks]

should be good. i have a 4 inch for mine.

Same here 4" Spal fan works great.I also went with the bigger oil tank.Check out this link,it is probably one of the best cooling mods I've seen. http://www.exriders.com/vbb/showthread.php?s=&threadid=446745&perpage=10&pagenumber=1

Thanks. That thread is great. What size oil cooler did you get and where did you get it? I can't find a good one for a good price anywhere

Its the cfm oil tank and is $99 shipped new on ebay. Just search 400ex cfm and you'll find it. I tried posting the link but can't from my phone. I just have the stock one now but will be upgrading it to the one that is in that thread before I build the motor

I meant the trans oil cooler. I'm looking at putting a bigger oil cooler on. I was gonna get one for a trans lol cooler from a car

The cooler that's in that thread is $70 on eBay from cxracing
