919 coolant temp too low?

I have a question for all you 9'rs out there. If your riding in 40-50 degree weather, how high up does your coolant temp gauge go when your running at steady highway speeds? I've only had my bike a few days and it's been on average 45 degrees when I've rode, but even after an hour of riding my temp gauge never goes any higher than about an eighth of an inch off the dead cold mark. I can even place my hands on the engine at stoplights without getting burned. I think it may need a new thermostat. The manual says the gauge needle should be about midway when the bike is warmed up. When you are riding in the cold, do your bikes run cool too???

Yep, sounds like it is time for a new thermostat. I had the same thing happen to me when on vacation this summer up in Maine. That sucked. I had to use duct tape to tape off about half of the radiator to get the temp up some.

i've ridden my bike for 7 months now, and that's exactly how it behaves on the highway, down to that you can put your bare hands on the engine, even after an hour of riding. your thermostat is perfectly fine. this is how the bike was designed. be glad, and happy riding!

also, the bike has had 2 services, 600 and 4000, and my mechanic loves money. if there was an issue, he would have mentioned it.

I think your gauge is fine. When I ride in cold temps (sub 50) sometimes the needle drops below the line by the C. If it is really cold it almost drops below the C.

You see the little notch in the line right above the C? That is where the needle will set when cold outside and moving. Condition normal.

My Hornet seems to run very cool when at constant speed.
Traffic lights is what those bikes don't like.
Otherwise when the thing is moving, the needle is always a hair off the bottom mark.

Today I rode in the city for the first time, and after about 20 minutes of stop and go the temp reached the middle of the gauge, and when I hit the highway it came back down to the break in the line right at the c. It sounds like yours all do the same, so I guess it's fine. Thanks all!

I know the problem's already solved, but mine is exactly the same way. Stop and go traffic will bring it up to the middle level (the fan kicks in sometimes), but as soon as I'm on the freeway it's back to the line between C and normal.

My 919 is only 7 months young and it runs very cold. I'd say thats normal and desirable.

Ditto on the cool running with my 06'... Thought my guage was broken when I bought it... but in stop in go... temps jump up to the mid line or so as expected.

Pass it on.
