BEST RADIATOR TO USE FOR 400/600 CONVERSION

[Fzrmike33]

Ok guys who have done the 400/600 conversion, im using a 95 fzr 600 motor in my 90 400 frame, rounding up final parts. I need to know what is the best radiator to use ? from what i hear the fzr 600 radiator dont work, so would love to hear what radiator to buy ?

mike,

I haven't done it but I think the FZR 600 radiator is the way to go. You are right - it doesn't bolt in on the stock mounts because the fan can't clear the engine. You have to fabricate some new mounts for it.

Some smarter people should be along here shortly to add some experience to this thread.

Dunno about smarter in my case but it has been discussed before and what came up was :

Mike, if someone wrote "you can't use the FZR600 radiator on the FZR 400" then they were mistaken. You can make anything work. Nothing with enough cooling capacity will be a straight bolt on. There is no discussion there, but you must realize that you will have to mock it up on the bike and make some simple sheet metal brackets.

What have you picked then is it the fzr 600 rad ?
I'm still looking for myfzr4/yzf 6.I also have the 400 fan hitting the front fender with hard braking.

Ok thanks for the information i will use a fzr 600 radiator then.

The discussion has been on this board before and the link is pictures of what what was discussed as alternatives as we are not all other makes savvy.

Basically any rad can be made to work just be sure it is big enough to cope with the hot engine of an FZR 600.

Fitting it all together is where the work & ingenuity comes in, no matter what you choose the thinking & metal work is down to you.

I used a YZF600 radiator because that is what I had. Of what is known to work (FZR600, YZF600, F2/3, ZX6) it would be difficult to say what is "best". As George intimated above, a little creativity will go a long way. All will require custom mounting, and two (YZF, ZX6) provide ports for an oil cooler. I personally like the aluminium ZX6 radiator cuz it looks bad a$$.

Ok i like badass, i may consider the ZX6 thats a Kawasaki, any particular year ?
