Pasted; (Pictured) is out for delivery right now. I've got a two-part. First, how do I clean a bike? I've seen people at the spray wash, but they all had faired up sportbikes. I've got an aircooled standard. Do I just not clean the engine? Wait three hours so it will cool? Part two: Application tips for a tank pad? I don't think it will be hard to smooth, but I'm wondering if I should prepare the surface somehow...
