    Hi
    How does the normal cooling process work with this 1200F model2010?

    After having RC36 and RC46 for 10+ years my new bike starts the fan much earlier.

    Actually we have 15C outside and ridding alone on local roads and a bit highway 80-120km/h (no city use or traffic jam) when driving for 3-10min in a village the fan would start, specially when I stop at a junction or at the gate when I get home.

    This behaviour is the same if riding with my friend (+90kg)

    My RC46 had side panels but could do more even in the summer. How will the big VFR12 works in hot days?



    I got the bike right now from the Honda dealer shop after oil, filter and coolant change. I have driven it just 300km, has not to much experience with it.

    The Tempr. bar display shows 2-3 marks bellow red when driving at least 80km/h. I shows 2 marks bellow when the fan starts.

    This morning I checked the temperature of the coolant pipe on the left side connecting to the water pump and also the radiator with a laser termometer.

    I found in 2-3 minutes in warm up the pipe is already 60C and the right upper side of the radiator is also warming.

    Is it normal?

    I read in the service manual the thermostat should start to open to the radiator at 80C, not before.

    But I know, an early thermostat should only expand the warming time but not to generate more heat.



    Bit problem could be, the bike is stock but the radiator shows some wear/deformations on part of the lamella.10-20%

    Worth the open them a bit with a thiny flat screw driver?

    How to clean it in smooth way?

    (I asked the shop, but they couldn't do too much)
    I have already checked the reverse tank, it is toped to the max. and filled with clean Honda-green coolant.
    Can it be the radiator is not full, or cannot breath out?
    Is it an issue I have to handle seriously?
    I am a bit worried, the dealer will not really willing to replace the radiator since it is a 11 years old bike and I cannot imagine those deformations I could flattened out without making more damages.
    How this big engine runs in hot summer days, does it burn the legs or more rider friendly?


    Thank you for your advices!

    Peter
