When putting my bike bake together after removing my pair valves, I don't know how but I forgot to mount the horn. I hit the front brake and it poked a hole in my radiator. It only got one fin but, I'm looking for ideas, and options. I'm working on a budget here but I'd rather not skimp. Maybe try JB Weld? Worst part is I should know better. Ive been working on my own bike for ten or more years.
