radiator help.

[jcs003]

anyone know a company that does custom radiators or a OEM rad that will fit in the frame rails of a 400EX in front of the stearing stem???

i think the YFZ rad may work but need to know the dimensions of it.

thanks alot.

anybody...

How about a BANSHEE rad or an old LT250R rad ?

I know they were monted in front of the steering stem.

:devil:

[jcs003]

i would need the dimensions to see if they will fit.

Check & see if you have a Motorcycle wreckers near you!

You'd be surprised how you could get a bike rad to fit on the 400ex frame.

I read an article in Dirt Wheels a while back where they built a 500cc 400ex and it had water jackets welded to the cylinder and they used a bike rad for their build and they said it worked good!

:devil:

that was four stroke tech's liquid cooled 500EX. i tried to call mickey dunlap and he won't be around until monday. i hope he will tell me what radiator he used and how he mounted it. the 250r rad can work but the clearences are very close.

[Langbolt]

Yeah!

That's the one.

Hopefully Mickey will remember which rad he used & will disclose that info.

Keep us posted!

I may have to put a 250R motor in my 400ex frame afterall.

alot of people will disagree with this statement, but i believe the 400ex handles better for a woods style rider. i have a stock framed 86 and its great but it can be twitchy. my 400 feels like its on rails. hopefully i can balance the benefits of the 400 and 250.

My 250R "IS" on rails!
I haven't run across anything that can corner with a 250R.
Just my 2 cents!

As far as Radiators go:
You might have to look around at the local bike dealer and see what may fit on there..........bring a tape measure and see!

I know theres somethin' out there! Maybe a early Ninja 250?

don't get me wrong, my 250r handles nice but it seems i have to slide it more than on my ex to corner better. either way, they both are great machines.

i have the 250r rad, but it is a tight fit with my pipe. i would have to offset it in a way that will prevent me from filling it. i found a street bike rad that will fit between the front frame rails.

kewl!! what bike? got any pics of it? do you have a project thread on this? :cool:

the radiator is for a kawasaki vulcan en500c (13.5x6.5) i believe it has bigger outlets but that doesn't seem to be a problem.

i haven't got the rad yet but money just got tight. i will get it soon and confirm it will work.

i haven't started a project thread because i do not have a camera to upload pics.

the only issues are "best" radiator placement. which i have solved and the inner tie rod end hits the pipe. to solve this i need to cur out about an inch of the header and have it tig welded. there is no issue with the suspension travel where the pipe is between the a-arms as most people would suspect.

i know all too well as to what your saying about the pipe hitting, as well as the issue with the rad having to be offset and hiding the rad cap. i built a '03 stroker just last year. i'm wanting to build another one but, for myself :devil: they are fun as hell to ride.

i juss happen to be reading the threads and your's caught my attention. thought i'd follow up on it. :cool:

it will be awesome. i am getting impatient. work slowed so i have to be patient. i want it to look professional so i aint just hacking and welding.

the wiring is my new problem. i am going to have to make munting brackets for cdi, regulator coil atc. and don't know where to start.

i got the street bike rad between the front rails from mickey dunlaps 500ex. i haven't been able to get hold of him to find the specific rad he used. i may try to contact him again today.
