Oil Cooler

[Gatorman199]

I am interested in buying an oil cooler for my 300ex. Can i just slip it on or how does this work. What would be the best to buy and apprx. how much would it cost.

I am pretty sure u have to do some thread tapping near the oil pump and run a supply and return line. I am looking to get one too so post whatever one you get and how you like it.

Four Stroke Tech has a bolt on oil cooler kit for the 250x/300ex that replaces the oil filter cover. I'm pretty sure the drilling/tapping is only for the 400ex.
