Do any of you know of any companies that sell oil coolers for the 300EX or if you could put a 400EX oil cooler on the 300EX?

 

I've seen them in the JL catalog.
do a search for "james lucky atv" on the internet.

 

You can order an oil cooler from FST, comes with hoses, it is bigger than the 400EX's oil cooler and probably cheaper. You can also get one from Jagg but they are more expensive. I don't have FST's ph. # right now. I got the FST oil cooler kit for my Warrior and my friend got one for his 300EX. Mine requires drilling and tapping, his did not.

 

Does fst have a website?

 

I have checked all over for a FST web site and have not been sucessful. I checked that Jagg oil cooler and it cost to much money. One was like $190 and the other was $220. My engine may get pretty hot but not that hot. I think I read somewhere that the FST oil cooler was only about $70.
