LC Temperature Gauge

#1 Post by fjurca » Sat Jul 20, 2019 2:44 pm

Any insight on this would be appreciated.

Noticed while riding the bike after about 20 minutes the gauge climbs to 3/4 in the 'green zone'. After about 30 minute it dances close to the red and after about an hour it touches red recedes and climbs. Never does enter the red.

Temp was 31c and no real traffic delays. Is that normal or is that running on the hot side for too long.

Thanks in advance!!

Looks like air in the cooling system.
I live in Arizona where the temperature was over 100 degrees and my gauge never teaches the red zone.

Seems a little hot.
Never seen mine over 3/4 in the green.

LCs can get hot sitting in traffic and they can also get hot running in the power band for extended periods. Nature of the beast that doesn't have a thermostat in the cooling system.

Exactly the kind of info I was looking for.

Flushed the system yesterday and put in Engine Ice coolant. Ran the bike for a good hour and the needle never went past half.

Thanks for the responses - big help!!
