Engine Temps?

[erniebearskin]

Engine guru's, I have a 2011-300 2T and recently installed a Trailtech bike computer, it reads glycol temp and will flash an amber high temp warning then a red high temp alarm. However I need to manually input the set points, and am a bit lost as to what is reasonable for warning and alarm temps. I raced a local race on Saturday and steamed a couple of times, max temp recorded wad 115 deg. Any opinions on setpoints?

Calibrate it in some hot water against a known temp gauge.

Ideal running temp for a 2 stroke would be near 50 deg C, 60 is fine, 70 ok, but losing power, 80s a bit hot, but snotty conditions might get there. I have never run a temp gauge on a dirtbike, maybe it would scare me.

115F=46C, so bit odd there.

I have mine set for the amber on at 93 deg. C and the red to flash at 104 deg. C.
With a themostat installed, mine will run about 58 deg. C. in most riding conditions if clipping along in 3rd or higher.

To clarify my original post my coolant temp was 115 deg, not ambient. Ambient was 30 deg C.

I set my amber for 160*F and red for 180*F. Alerts me well before it would boil over. My engine temps are usually 120* to 130*, only increases when I get stuck in trail trash.

Roughly the same as Neil when I had a Vapor on my KDX.

I might put mine ten degrees closer to boiling (100C/212F).
