Does anyone know if an oil cooler for the 400ex can be modified to fit on a 300ex or a 250x, or does somebody make a kit that you can buy. If where can you get it??? any info is helpful!!!!!

 

My friend got an oil cooler for his 300EX from FST(Four Stroke Tech), for under $100. I also got a kit for my Warrior. Mine requires drilling and tapping, his does not. Jagg also makes oil coolers but they sell for over $200.
