I have searched and haven't found a crack like mine. Wondering if this is a repairable crack or total loss? I don't know much about welding and I'm trying to see what the consensus is before I go looking for a new frame. I'm also going to look again on the mating welds for cracks like I've seen on other yz450f. I bought this bike from a vet expert who raced both track and scrambles last summer in Florida with a good amount of hours on the bike minus freshly rebuilt engine. I've been finding lots of things needing replacement and though I was almost done until I found this.
