614busa Posted July 8, 2011 Report Share Posted July 8, 2011 The bike doesn't over heat but it stays above 200 even on the freeway I changed the fluid flushed the system changed the thermostat still same thing anybody had this problem?

Wicked1 Posted July 8, 2011 Report Share Posted July 8, 2011 wa wa water pump? Remove the thermo entirely and see if it still stays high. 200 is O.K. 220 is another story. Quote Link to comment Share on other sites More sharing options...
Wicked1 Posted July 8, 2011 Report Share Posted July 8, 2011 also check your radiator for dirt and debris between the fins- it also could be blocked. are your fans working correctly? Quote Link to comment Share on other sites More sharing options...
614busa Posted July 8, 2011 Author Report Share Posted July 8, 2011 Yea fan comes on at 220 drops to 210 then its goes right back up to 220 my buddy has the same bike his runs at 180-190 on the freeway Quote Link to comment Share on other sites More sharing options...
InyaAzz Posted July 8, 2011 Report Share Posted July 8, 2011 I had a friend who had an 06 750 that did almost the same thing. It was considered normal. Quote Link to comment Share on other sites More sharing options...
wht_scorpion Posted July 8, 2011 Report Share Posted July 8, 2011 (edited) You do not want to run auto antifreeze their some thing in it that grind down the water pump fins If you do say good bye to the water pump check the water pump fins run water wetter or IceTry to burp the radiator make sure antifreeze is at a good level Edited July 8, 2011 by wht_scorpion Quote Link to comment Share on other sites More sharing options...

redkow97 Posted July 8, 2011 Report Share Posted July 8, 2011 Just do a coolant flush to be sure everything's kosher there. If it's been more than a year, it can't hurt anyway.I run distilled water and water wetter, and my bike only sees 220 after it's been on the track for 20 minutes, and I slow to pit speeds. Otherwise it stays around 200, even at 15,000 RPM.Granted, I'm going a lot faster, so there's more air coming through the radiator, but I'm also probably at triple the RPM...Water Wetter is NOT anti-freeze, so you'll need to flush the system again in November; but it's not like distilled water is expensive...

Jamez Posted July 10, 2011 Report Share Posted July 10, 2011 Probably different bike to bike but I run over 200 all the time.As long as fan kicks on about 220, good to go Quote Link to comment Share on other sites More sharing options...
ReconRat Posted July 10, 2011 Report Share Posted July 10, 2011 Thermostat or ECT (engine coolant temperature) sensor. Thermostat opens at 180F on that bike. The radiator cooling fan comes on at 220F, and shuts off at 212F. The ECT will read temperature based on resistance. Any additional resistance in the wiring between the ECT and the "computer" would read a higher temperature.Easiest fast check is to put a good thermometer in the coolant fill port. Observe when the flow starts as the thermostat opens, observe the temperature of the coolant on the thermometer, and observe what the temperature at instrument cluster shows at that same time. Be prepared to put the coolant fill cap back on quickly and/or shut the engine off. Judge which is off, the thermostat or the ECT.A thermostat that is wrong, will need replacing. An ECT that is wrong, needs to have the resistance checked right at the sensor. If the sensor is ok, check the wiring for resistance (bad/dirty connections).This would also "burp" the system if necessary, by letting the system push any air out while you've got the fill port open. There will be some motion or expansion before the thermostat actually opens and coolant flow begins in the system. Keep the coolant off of painted parts if it overflows a little. Have a water hose or something ready to flush it off stuff.But basically, in hot weather like we have now, your temps should stay between 180F and 220F, as displayed on your instruments. That would be normal. Actually, at all times, that is the operating range. Quote Link to comment Share on other sites More sharing options...
