Yes it is!! I need the Thermostat,,, Motor takes a long time to come up to operating temperature,, $29.40 is a lot to pay is a auto thermostat is the same part
More details about your symptoms? How many miles? What outside temps is the bike being started in? The 9er is slow to warm up then other bikes because the engine is under stressed & has a low compression ratio. So may be you do not need to do anything?
Also, when the was the last time a coolant flush was performed (if ever)?
The stock thermostat is 180 F and unless you are riding hard or in stop and go traffic, the temp gage will barely get past the cold mark. I removed mine and tested it in a pot of hot water on the stove and it was right on. Chances are that you have nothing wrong. I replaced mine with a higher temperature one for a car. It was a very close fit but had to dremel off maybe 1/8" on one side of the flange to get it to sit flush in the housing. Now the bike normally runs around 1/4 on the temp scale. I did it to experiment and see if it would lean out the exhaust to help with the stink. Seems to have.
This is the one I used. Available at most any auto parts store.

Thanks. I was going to test mine for the same reason.
I was blown away at how cool the 919 runs. I don't have a lot to compare it to, but both the Street Triple and the 599 get hot no matter what the temps. The 919 will stay stone cold if you are going over about 55, no matter what the outside temps.
Just more proof that this motor is VERY under-stressed.
