I empathize; I avoided installing T bobs on my Gen1's until the T bob 2 was released - a much cleaner install IMO than the original.

Are the ProCycle brand of radiator by-pass kits still being sold with the 180F thermostat?

Or have they up-graded to the 195F thermostat that is Finally being produced in China in the proper oem KLR size.

Living in a higher altitude, cooler climate the 195F thermostat would be most beneficial.

According to their website it’s still a 180. In my experience this is still too low. Although I didn’t scientifically measure, I don’t perceive any difference in warmup time or operating temp since installation...same old wild swing. I’m glad to hear there is now a 195 stocker available.

I'll suggest that you should use the 195F Watt-man Thermo-Bob 2 thermostat in the ProCycle radiator By-pass assembly if possible.
Better yet, purchase the Watt-man Thermo-Bob 2 in the first place.

Thanks, I’ll order the thermostat from Watt-man. Too bad his gen 2 wasn’t available when I installed mine.

Out of curiosity, will the 180º pro-cycle thermostat fit into watt-mans thermo bob?

Please do not lecture me on the effects of temperature and density altitude on an internal combustion engine -Thank you.

Yes, it will. It is the stock KLR thermostat and the thermostats that watt-man uses are identically sized to the OEM.
