Exclamation KLR 650 - 2015 A leaking Radiator expedient

Got my KLR 2015 new. Still love it 4 years later. Great commuter bike, gravel road bike, Not so good on rough OHV trails though, a bit heavy.

16K on the Odo now.. Lots of drops, always field repairable - (or limp home-able).

Today, trashed my radiator in a fall. Had 70 miles to go to get home. Called a dealer nearby - but he only had OEM 2015 radiator at $900!!!

I thought I would try to get home. I Tested rideability, but Red lined the temp gauge every .5 miles - had to stop and air-cool each time so I did not ruin the engine - until I figured this out:

I found an auto parts store. Got a gallon of antifreeze, and a funnel (had to pick the right one for safety as I explain below).

I rigged the funnel (had to fit and not impede turning) to the radiator opening. Tried to pour the antifreeze in, but it would take only a few Oz before it came up to the leak level in the radiator. (Left the cap off, did not want to pressurize the coolant system as it would force any antifreeze out faster.)

I found I could ride 3.5 miles until near red lineby doing this.

At first I stopped, poured in a few Oz of coolant and started again. did this about 5 times. Finally figured out I could safely pour from a trashed 16 Oz water bottle into the funnel while riding. I could go about 15 miles at a time until I had to stop and refill the 16 Oz bottle.

I wonder what the people who passed me by thought as they watched me pouring what something from an old soda bottle into the front of my bike as they passed me!

Now - got to figure out whether to send the radiator in for repair, or try the aftermarket 2014 radiator/fan replacement. (2015 radiator is just different enough - and I'm not paying for the OEM $900 replacement.)

Hope this helps someone in the future.

ANYBODY else have another solution to this situation?

Mylers Radiator Repair in UTAH does an amazing job on some ugly stuff for a very reasonable fee. Or they may be able to alter the normal fan brackets of the other series of GEN 2 radiator?
Or sell you a new Myler Super Cooler radiator for MUCH less than oem. https://www.motorcycleradiators.com/

Modify at "YOUR OWN RISK"!

Still riding my 1987 KL650-A1. 85,000+ miles & counting
