On the temp gauge i am running about half way of the gauge. I put the engine ice in it to maybe help it cool a little more. On my old f3 600 I took my thermostat out and it ran so much cooler. I spoke to a few people about this and they said that by taking the thermostat out it wouldn't keep the coolant in the radiator long enough to cool it before entering back into the engine..but that wasn't the case for my 600..Not sure if there is a difference between the cooling of the 600 and 900. Any help?

 

very good ques. i just took mine out so when i get all the kinks worked out i might be able to help you out with this one
but deff would like to know others comments on this
as i have never keep a therm. in on any of older cars as only neg. resalult was
that it took cpl min. longer to get warmed up.
making it lil more cold natured. and that dont bother me at all

 

Anything will run with the thermostat removed. The problem is that the engine is designed to operate at 220 degrees, and all of the internal engine tolerances are designed to be at the proper gaps when the internal parts expand at that specific temperature. A thermostat is how the engine regulates the temperature, and without it the engine temperature is all over the place depending on how you are riding, the temp outside, traffic etc. If the engine cannot regulate the temp, it may not make that much of a difference in your riding experience but it is definitely making a little less power, a little less fuel economy, and a little more internal engine wear.

And BTW, I think half-way up the gauge is exactly where it is supposed to operate. If it starts creeping up to the high limit of the gauge under normal riding is when to worry about it.

 

I have to agree with MI900. Instead of taking out the thermostat its better to service the cooling system first.
Not really sure where the gauge should stand in normal riding condition; it could varies but I guess it shouldn't be up more than the half mark. I had mine slightly higher than the half mark previously when I ride hard or idling too long; serviced the radiator and now it hardly goes beyond the half mark even the engine is idling and the fan will kick off too before it reaches the half mark. I guess there is nothing to worry unless it hits the redline.

 

mine is been sitting half on the gauge under normal ranges
but tonight its a lil cooler then i have had it out before
about 66 or so out side and just got back from a 140 mile trip and all night its been under half way on the
temp gauge.
good thing id say but if eng. is made to run at half way ill have to run at 20 mph to keep it there at half way lol all night.
