I have read a little on here lately about sticking thermostats....Some mention was made that after warm up there should always be 3 bars showing...Does this apply regardless of temps?.....in warm weather after warm up my 06 ST1300 always shows 3 bars but in colder temps that isnt the case....in the 40s it may drop to 2 bars...In the 30s I've seen it at 1 bar...When I stop for example at a light it quickly goes back to 3....Do I have anything to be concerned about?...Comebacks appreciated...Bill
 
Should always be at 3 bars... your t-stat is sticking a least a little... because in cold weather it should be closed until the engine warms up the coolant to a temp where it needs to be cooled off, triggering the t-stat to open and flow through the radiator, cooling off the fluid.... since it's stuck open, the coolant is cooling more than necessary and causing the overall engine temps to lower...

It's something you would want to address eventually, in the short term it will mean you will get lower MPG numbers but shouldn't cause you to be stranded on the side of the road.

Replace your thermostat, its corroded and starting to stick open.
You should always have (3) bars when warmed up.

Once again, Mellow beat me to the reply :D
At least when they fail, they stick open and not closed.

Hey I ain't naming names. No need to throw somebody under the bus. :well1:
I already did that in a previous posts. :rofl1:


Truth be told I was looking at the same massive leak after the cap went back on thinking rut ro cracked cap. I didn't see the ground terminal right in front of my face. :doh1:
 
It was a learning experience... for me too... Heck, I helped him the first 3x. Just can't see it from the other side of the bike.

Sometimes things so simple can trick ya.... I won't admit it about the time I forgot the oil plug during a change ( till I saw the puddle ) ! :)

And don't worry, I'll give him a hug next time I see him. :O No bus intended. ( the crotch protector is another story )

PS..will try and make it this yr agn to tech, no work needed but will bring tools and helping hands.
