Engine running cold

[Butcher]

Have noticed that unless it's hotter than 75 degrees out there bike temp when running down the road it won't warm up past 160 unless it's just idling. Once i start moving again the temp comes back down to 160. Is this normal?

Yes... It's just the overall temp of the cooling system... Start spinning some rpms and working the motor you will see the temp climb- I have seen 210°F when at the track... Just normal cruising/riding is not gonna show temps above 175-180 from my observations...

You're in the normal zone with those readings.

Stop and go driving at 80 deg ambient will have you close to 200 before you know it. And summertime stoplights will fire the fans at 221 on a regular basis.

FJ has big radiator and cools well when moving. Heats up quickly at a standstill.

My engine stays around 100 above the outside air temp when moving.

Just seems weird to me. I do mostly commuting albeit well above the speed limit but just wish I could get the temp up because when it's hot out the bike gets another 4mpg better.  I even tried tapping up the radiator this past winter.  It helped a little bit.  If this was a car I would have put another t-stat in it already. Thx everybody.
