Coolant boiling out?

The same thing happens to water heaters in homes. Granted, the problem will only happen over a long period of time, but it does happen.

Thanks, I knew that from my automotive experience. I used tap water, but I figured it was only going to be in there for a couple days at most and probably wouldn't cause much harm.

Have been driving around in traffic today and it is a bit cooler, however the temp seems to be behaving. I will be keeping on eye on it for sure though until we get through a summers day of traffic.

I can see that.
but the sporty is air cooled.

Well bad news, she did it again while cruising around town last night.

I decided to pull over in a parking lot and address my beeping cell phone. While replying to a text I figured I would leave the bike on to test the over heating issue.

Slowly go up to about 226, and the outside temp is maybe 70? It was a cool evening. Bike was definitely not being run hard, but I was going from stop light to stop light around town.

The bike started boiling out around that temp and I figured I would let it keep going to see what it would do and if it was only a minor issue. The temp continued on up to 230 where is was definitely not going back down with the fan on at full speed.

I figured this was getting good and decided to get the bike rolling and within seconds of cruising in 1st gear the temp came soaring down.


Gonna pull the fairing off today and address the issue. Maybe T stat or something that might have been damaged when it was layed down on its right side? Might even have an air bubble or two, will try to bleed it today.

Ideas, thoughts?

is there a bunch of shit on your radiator so the fan can't suck air through it?

Don't forget that there is usually 2 lines on an overflow... one for when its cold, one for when its hot. If its up to the hot line when its cold, boiling over is going to happen.

When it boiled over last night it emptied the entire reservoir. If it doesn't rain this weekend I am going to spend some serious time overlooking the entire cooling system.

Check the Radiator Hose might need to reseat it slide it foward on the radiator and re tighten down i had it happen with my SV. Just looseened it enough to slide it foward on not pour out then re tightened it and whalla it was fixed unlless that is not wear leak is its late and im tired lol.

Did you say the fan was working? should come on around 210-218

with the bike cool, remove the rad cap, start it... watch the temp. Around 160-180 degrees the thermostat should open... then with throttle applied you should see movement in the rad thru the cap opening.

if not, then you must determin if its the t-stat or water pump that has went out.

I will try that tomorrow. I haven't been able to address the issue yet, but I have my morning planned for the bike. Going to change the oil and spend some quality time with the coolant issue.

my best advice...

work on one issue at a time.

Otherwise its hard to figure out what is going on and what is wrong or what you THINK fixed it.
