Hi, I am new this this forum. I recently bought a 2000 929. It has been running great for the past 2 month then all of the sudden when i riding in the city, the bike started to run hot, 234F but the fans did kick on. I stopped the bike and parked it. Coolant was coming out of the top of the smaller radiator hose on the right side of the bike under the cap that leads to the lower part of the fairing. I added more coolant in the radiator and the same thing happened. I drained the fluid and the same thing happened again but every time it does it, the temp on the gauge reads under 230F. What do you think the problem is?
Thanks,
Jeno

 

this might sound stupid since i'm not really technical with bikes but ill throw this one out there anyway. Could it be your thermostat is malfunctioning?

 

if the fans are comming on it could be the thermostat or i could be a bad water pump possibly, or mabey a clogged radiator.

 

So that wasnt such a bad suggestion eh? I'm learning more and more on this site.

 

Also check to make sure your rad cap isn't blowing off prematurely.....could be as simple as that
