Leaky 400F Radiator...

I bought this bike...Not much time on it. 1999 YZ400F.

But when I flushed the radiator...Problems. I must have washed the corrosion away that caused a couple of pin holes.

Anyone try "stop leak" in a motorcycle? Want to be sure it will not hurt the remainder of the system.

I hate to spend the money if I can band-aid it...I brought it to a shop...They cannot fix it...Said because of where the pin holes are...Not from rock damage...

Thanks for the input!


I bought a new one for now...But I will call them to have this one fixed!
