He does like to let it idle for about five minutes to warm up before he starts to ride. He does not use radiator guards.
He told me that it overheated the other day while it was warming up, cooled down when he started to ride and then overheated when he stopped for about three minutes while talking to a friend who just ate it. I imagine he is letting it idle to long and has lost some fluid along the way, a little bit at a time which has finally caught up to him and presenting itself as overheating
now. If he tops his radiators back up and shuts his bike down when he is not riding I think this should take care of it. I have to wonder though if he has done any other damage internally. He's the kind of guy that can ride like a Carmichael but has the mechanic ability of Homer Smith. He should have got a factory ride cause staring at a bike scratching your head won't fix it. Anyways if I find it is something more than the usual I will definately post it. I can't imagine too many people are having overheating problems because I couldn't find one previous post addressing it, even with an extensive search. Thanks again everyone.
