How do I fix a motorcycle radiator leak?
It's a 2003 CBR 600 F4i, looks like a rock must've come up from the front tire, cause it looks like it's leaking from the front-center of the radiator. I read somewhere that the stop-leak pellets and whatnot aren't good for the performance of the radiator,
I have use Bar's stop leak black pellets in my 82 Yamaha radiator as a preventative for 27 years with no ill effects. It comes in a clear plastic jar and I add 1/2 of the jar each time I flush the radiator. I don't know about the newer performance bikes
