My radiator started leaking but it's leaking from what appears to be a seal, is this fixable or do I need a new radiator?

 

I've never encountered this before. If it were me, I would take it to a radiator repair shop. If anybody has a definitive answer, it would be them.

 

Fixing around the seal is the worst - if it was on the metal one would just jb-weld it and it would last forever, but around the seal is hit and miss. You can try it of course, what do you have to loose?

A replacement scrap unit would cost around $40, a beautiful all aluminum welded unit is $200 so it depends on how long you intend to keep the bike and how much you love it.

As for repair - to do it properly would require disassembly and resealing, I'd expect that to be a lot more than $200...
