Here's a picture of my Thermo Bob Original in the usual place:
It works great and always has. It's perfectly positioned and doesn't shake, rattle, or roll. The problem is that it tends to get in the way when I need to get the valve cover off. Since I'm constantly fiddling with stuff, that's a nuisance.
What I wanted to do was put the new Thermo Bob 2 on, but I wasn't sure it was going to fit underneath the IMS tank. I contacted Watt-man and asked.
Sure enough, it won't. Underneath the IMS 10 tank there is about 3/4" of clearance between the thermostat housing and the tank. Bill told me the Thermo Bob 2 housing is one inch thick.
He suggested that I might try a Thermo Bob 3, which he originally designed for the Ninja 250 and which is used on snow machines and such like that.
He very kindly set me up with this kit:
The only thing special about this kit is that he didn't install the bypass hose fitting and added a 90° and 45° fitting so that I could fine tune the bypass hose placement.
I'm going to try placing the TB3 where the current bypass fitting is...
...and put the bypass fitting where the original Thermo Bob was.
Since this will be regulating the cooler coolant coming out of the bottom of the radiator Bill has installed a 185° thermostat.
The TB3 has a port in it for a coolant temperature sensor. I've ordered the proper sensor from Trail Tech and will install it. It will be interesting to see the comparison of the temperature at the TB3 vs the temperature at the head and the timing of those temperatures. The sensor should be here tomorrow.
Working at the Speed of Tom™, I should be playing with this next week.
