Bought a used one from a forum member here and getting ready to install as the weather is heating up. tried to contact the manfr several times several weeks to no avail. I'm aware of the situation, yet have waited long enough. I had hoped to purchase some new o-rings that ,I will now source locally, and to ee if they have a diagram on how it goes together thermostat spring toward block or toward filter.
Anyone have an instruction sheet for this, I'd like to get a copy for in my binder. At a minimum let me know what way to install the thermostat.
edit-> I suppose I better ask which outlets match up between the the thermostat block and the supply and return on the heat sink.

 

After searching I came across the info on jp website listed under motorcycle innovations oil cooler, link to pdf instructions.
In case someone needs it in the future
