Hi all. I have some smoke coming out of the bottom of my radiator. It's hard to tell where it's coming from because it's right where the frame hides part of the bottom of the radiator. I know smoke can come out of that area a bit if you are really working the engine hard but this is happening even when the bike is just barely being ridden. I topped off the coolant and it still happens. Any ideas? Do I have a cracked radiator? I know very little about how to work on the bike so really need some diagnostic help here. I'm distressed about this! Thanks all, N.
