Radiators are getting scarce, Anyone tried these two models on their 636 yet?

[oemsrt4]

I just put a fresh engine in my 03-04 636 and want to preserve it for as long as I can, My last bike ran/runs awesome, and the cooling setup never let it break 200 degrees. That is my goal with this new engine.

My first choice was an 05-06 636 radiator but didn't find any on ebay in minty condition and reasonable price. I was looking at maybe trying an 09+ R1 radiator since they have two nice Panasonic fans already built in, or a zx10 radiator and making my own R1/R6 dual fan brackets for it.

Here are some pictures for comparison:

zx10


I am leaning towards trying the R1 radiator with dual fans already built in out, wondering if anyone has tried it yet? I will have to make my cage and mounts for sure but its going on a steel frame so a off the shelf radiator cage most likely work anyways.

Let me know what you think!

r1 for sure

The R1 rad looks like it would be perfect!

r1 looks good, unless u want to spend the 250.00 for aftermarket brand new ones ive seen on ebay i was gonna go that route

[tipper13]

anybody tried those aftermarket rads there on ebay?

also, would love to see an r1 rad or something else rigged up to work

I just ordered a minty 07-08 R1 Radiator on ebay for $150 shipped and it already has the two good R1/R6 Panasonic fans mounted on it, I will report back with results as soon as it gets in and I get a chance to install it.

The Right side lower inlet that the hose coming from the oil cooler on the front of the 636 engine goes to looks like its maybe a smaller diameter than the R1 port. I will see once its in but that would be as easy as a trip to the hardware store and get a brass reducer and little piece of hose to get that to work if it is off in size.

The one I ordered looks just like this one..



I am thinking I'm going to try an aluminum strap dead center of the radiator splitting the two fans and supporting the lower radiator mount from pulling. Then use a steel strap material and tie into the two stock upper mounts which are defiantly too far apart bend in work...

We'll see once I get it what may work the best, Hopefully all goes well and possibly open up another radiator option for the 636 users.

Tuned in on this. I had to notch my fairings a little bit for 05-06 to work and they are starting to get pricey for sure.

I put that gsxr radiator on joes bike last year and it worked awesome. Big as hell but still fit under the plastics

Got my R1 radiator inIts suppose to be 90 degrees tomorrow so its going to be put to the test. If it breaks 200 degrees a 3rd fan will be installed





The 03-04 636 radiator cages almost fit on this radiator.
