I have a 99 yz400f, and one of the radiators is leaking. Does anyone know if it is okay to put a stop-leak kind of substance into the radiator? Is there something made specifically for motorcycles?

Do not put stop-leak in them. There are a bunch of companies that specialize in motorcycle radiator repair or your local radiator shop maybe able to fix it.

I've had excellent luck using JB Weld to repair my radiator leaks.

Local radiator shop. I twisted one and smashed the inner two rows of fins on the other, radiator shop tested and fixed leaks. Never had a problem after that. Ironically it was a 99yz400 as well.

Myler's is good, fast, and fairly priced. Hard to top that.
