radiator/ oil cooler

[racer 557]

has anyone scene a new one for a 06 400ex i remeber one guy said they discontinued them or does anyone know of a bigger one that will fit

i would check ebay for one or you can get one from service honda or bike bandit if you are looking for a stock one. otherwise there are a bunch of different oil coolers that are oversize that fit on the 400 and work well to help cool the machine. there are some from cbr bikes that fit and one from a transmission cooler that work. FST (i believe) makes a whole kit for adding another to the existing system by tapping into the head and making another port to run oil through. I would search it to see if you can find some threads about it. I am not sure which ones fit and which dont. steve

i am not sure you can search in the 400 stuff to see what one works the best. i just have the stock one and it works fine for me. steve

ive seen people make a after market oil tank would this help kinda like a bigger radiator would?
