kdx radiators

Just thought I'd share some awesome news with the fellow shunned kdx'ers. Warp 9 no longer carries radiators for our bikes. Kevin at warp 9 told me that "although the kdx is a great bike, it's going by the wayside". A shared sentiment by many companies it would seem, as less and less parts become available for our perennial machines. It's frustrating and sad. Guess I'll start the arduous search on fleabay.

For E or H series bike? I know they list that they have the H series rads but not the E's.

not anymore, for either

Damn, that's a bummer. I was thinking of springing for a set. However, I don't blame them. It is not profitable to make them for bikes that the newest of which are now 6+ years old and was never as popular as the MX bikes.

No biggie it's not like they were ever needed, unless you just like wasting money

No, it's not like wasting money if you need radiators. They are discontinued for the E series and list for over $275 each

for the H series through Service Honda. Warp 9's radiators at $219 a set were a good deal for brand new units with improved cooling capacity. Even better when you figure in most of the beat up used junk people try to sell you on Ebay with crushed fins/tubes and corrosion for $60, $80, or even over a $100 each side!
Right now my right rad is partially separated and bent from the inner mounting bracket/flange. There is no way to get it back into alignment without destroying the core. I guess I'm just going to try to find a rad shop that will work on bike radiators in Tucson and pray they don't screw it up.

For a pair, undamaged? Yeah, I see usable ones for $25-$30 each sometimes but that doesn't mean they are in good shape. I don't ever see any in good shape for less than what I mentioned before and it is always for just one side.

deals are out there if you just look
I bought these before I needed them, could not pass it up for $40 shipped
All looked brand new
Actually my old rads worked fine they were just bent all up

Or send your fleeBay finds or old radiators to Myler's in Utah.
$35 or so, and they are straightened, cleaned, fixed, pressure tested, and good to go. I picked up a spare set for my other Green bike for next to nothing, had them serviced at Myler's. Easy. They can fix the worst looking damage.

They still make the kx500 radiators, and I'd bet they'd work with a little tinkering. I know the radiators off of an 89 kx250 worked on one of my kdx's and the kx500 series continued to share the same chassis as the 89 kx250 until they quit making them.
I just looked at pair on ebay, and right side looks the same - same hose locations and angles, the left side looks the same on top but the bottom is angled slightly upward rather than straight out. That shouldn't be a problem... the lengths look the same too.
I remember I lunched the radiators on a 97 KDX years ago, and pulled the radiators off of an 89 KX250 I had, to get by. The 89 KX250 shares the same plastics as the kx500 and the KDX shrouds hooked up. I don't remember the details of the installation but I know it was just a bolt-up affair.
If someone has a KX500 or knows someone with one, it'd be cool to see if they'd fit without a lot of hassle.

That certainly was a good deal. I have been keeping my eyes open for a good right side but nothing has popped up yet.

I might have to give them a call. Thanks for the info!

Good info. I also know the E and H series rads are almost identical. The only differences being the upper radiator mount is moved up on the H series and the louver mounts are different. A bracket could easily be fashioned to make either bolt on the other model and I don't use the louvers myself.

Decent but still tweaked on the right one. I looked at everyone on there and there are none that are not damaged in some way for under $60.
Eh, I'll just keep my eyes open and if I don't find one by the time I'm ready I'll just have mine rebuilt.

not tweaked enough to worry about
Never gonna stay straight anyway

Eh, I know for all practical purposes it will work fine but I just want it nice for my build.

Me too SS109, everything else on my rebuild is going to be new or look new. I don't want shitty rads as an eyesore on an otherwise immaculate bike. I did find some works connection rad braces on ebay last night and jumped on those immediately. Should save me from future headaches

Why? I don't want it to look like your bike!
Seriously, there is nothing wrong with having a nice looking bike. I have never had a new bike in my life or even a brand new car/truck. I want my build to be the way I want it and I want it to be like new. That may not be what you like, or what you think is worth spending money on, but it is my bike, my money, and my desire to have it that way.
