Last week I took the D12 to town Christmas shopping. the temp was around 36 f. the bike worked great but the engine temp. went from normal in the city, to about half way between the two hash marks on the guage when I opened her up on the back roads, on the way back home.
Today it's bright and sunny but only 34f out. There's no snow on the ground, and I can't stay off the beast. Can I put a piece of cardboard in front of the rad to keep her at the normal operating temp, like you would with a diesel truck in the winter, or could this hurt her?
With El Nino active I think we are in for an open winter, with very little snow. So I don't want to put her in hibernation yet.
