Hi, i've had my 2006 Brut for about a month and find that although I've had the major 12,000km service the bike runs hot around town and when stopped in traffic...and this is only the beginning of summer in Adelaide! When I turn off the motor with ignition key, the engine temp soars and coolant oodles out. So I switch off the motor using the kill switch, the temp soars and the fan kicks in. It cuts out around 94C, meanwhile the coolant reservoir overflow dribbles out coolant. I asked the MV dealer to lower the fan temp threshold to make it kick in at lower temp but was told can't be done with stock ECU/electronics. The worrying thing is that in the two weeks approx. 400km since the service I've lost so much coolant that the reservoir was way below minimum and exacerbating the problem. Hmmmm...
i've seen a suggestion in this forum to replace the stock plastic fan with a Muzzy aluminium one (http://www.motovationusa.com/mvstore...?idProduct=731
) and also an MV Agusta F4/Brutale Water Pump Impeller Upgrade Kit (http://www.motovationusa.com/mvstore...?idProduct=826
). Anybody have any tips for me installing these?
Lastly, what about using distilled water and additive water wetter? (Red Line Water Wetter Engine Super Coolant http://www.motovationusa.com/mvstore...?idProduct=792
). The spiel says, "The best coolant you can use in your bike is distilled water. Add Water Wetter to further improve cooling up to 20 degrees. For some bikes like the MV Agusat F4-1000 that have severe over heating problems, use of this with Muzzy fans
for better airflow is almost a must have mod for your bike during hot summer months." Says its compatible with antifreeze to improve the heat transfer of ethylene and propylene glycol systems.
I'm currently runnning a new batch of IPone Radiator Cooling Liquid that contains ethane (antifreeze/anticorrosion for aluminium/magnesium crankcases). Should I use the water wetter with this or should I dump it and put in only distilled water?
any ideas much appreciated, cheers, Claudio
