Back from a 2-day tour with friends, cleaning the bike I notice a spot in the central area of the radiator. With white blotting paper I clean, the paper absorbs and turns blue ..... coolant coming out !!!
I check the sleeves, I look good everywhere. but nothing not known any loss. I turn on the bike and let it idle until the fan starts, drop the liquid starts to come out.
So I decide to take it all apart, never done but I can do no damage. The next day I bring the radiator from a radiatorist, I explain what happened, no trace of stones or other traumas, in fact I set up a protective grid, he performs the necessary tests and we see the loss. Unfortunately, the radiator is "blown up" and cannot be repaired, if there is a liquid turafalle but it is only a palliative.
This morning I ordered a new radiator from the dealer, a small charge of € 525 plus the liquid.
I'm really puzzled and angry.
Never happened in my motorcycle life
