THERMOSTAT FOR R2

[Rick Allen]

The manual lists the factory thermostat at 170 degrees but seems one of that temperature range is hard to find so what is the best choice for an R2 engine, a 160 or a 180?

I should add that the engine is newly rebuild, so I would imagine more friction initially so more heat?

I've always run a 160 in my R2 without any problems.
