The stock KX500 cooling system work good on a stock engine under most conditions.

But there are some of us that push that system to the limit and beyond.

Apparently the boys over in the UK noticed that when modding the SR's cooling system needed some help.
I found these obscure posts somewhere on the net that got me thinking...
The u.k sr500 90-91 perimeter frame had new separate cast head with 2 inlets at rear this was changed to inlets at front with same casting but machined inlets , In Parallel rads
In European Grand Prix kx500 cooling was a problem all factory and semi factory bikes went to in parallel cooling like the 90 onwards kx250
Maybe because we did not have the massive u.s tracks for cooling but in stock config std kx500 system was no good
for Grand Prix , The U.S Sr500s had the rads pushed out on spacers i believe which made the rad cowls looked flared out
My Sr500 is non perimeter , KHI hand assembled Tig welded frame . Ex Kawasaki U.K bike which was the KHI 500GP Team
Its is thought the 2 inlet kx500/sr head was modified stock not a new casting .

Re: SR500 Head KX500SR cooling in Parallel
Since I have discussed the potential of parallel cooling on other forums I figured it was time to take a closer look at parallel cooling.
Here is some pics of a modded OEM head that has been modded for parallel cooling..
More to come...

First, what is parallel cooling?
Let's start with how the factory routes the hoses on a stock KX500..

Here is one example of parallel cooling.
I say "one" way because there are several variations...

Re: SR500 Head KX500SR cooling in Parallel
Here is a CR500 head that was modified by Adam Millar for his CR500 to KTM conversion.
This was set up for parallel cooling using a single outlet to feed the top of the radiators.
Obviously he will use a "T" to connect the top hoses to the rads...
