Title: Kymco Venox help needed
Post by: Ajvan on August 04, 2012, 09:04:22 PM: Hello

I've bought a new Kymco Venox a year ago - it has 4000 km. After a longer ride, while standing in place, for example on a traffic light, my overheat light turns on, about at the same time the fan turns on. It turns off after a few seconds. Sometimes after a long ride it keeps turning on on every traffic light - sometimes even many seconds before the fan. The thermostat has been changed and tested, it works well, the thermo switch and the thermo indicator have also been changed; the engine appears to work just fine, there is enough cooling liquid - nobody knows what to do anymore. Any ideas? ??? Thanks ;D

Maybe he's concerned about his overheat light turning on....

The radiator was checked, the water pump also - everything is ok. In a few days they will trie to replace the reley that controls the cooling system - we shall see...

If you make a problem, you'll have a problem. If you don't want a problem, no problem.

The only reason I'm interested so much in this problem is because the motorcycle is still under a guarantee so I'd like to get it fixed for free while i can, but nobody seems to know what's wrong with it or how to fix it, not even the kymco dealer in my country.

Thank you for your answers, they've been very useful - atleast i could give some suggestions to my mechanic.
