Hey guys,
I bought me '15 YZ450F new as a runout model at the end of 2015 here in South Australia. I had a pretty bad crash riding freestyle about 3 months ago, broke my hip and a couple vertebra's. All healed up and about to return to work, so naturally, i was begging to go over my bike and get it sorted as i had not seen it since the crash.
I've found a pretty nasty crack, straight down the center of the weld on the chassis, just below the head steam, (photo attatched)
Now, i know for a fact i wouldn't buy a second hand bike if the frame has had a crack in it and been re-welded, i feel like it would just always be in the back of my mind, but have people actually successfully re-welded there frames before, especially being in such a critical spot?
I was planning on selling it and getting a fresh bike once i'm back 100% healthy and fit. What other options do i have? Do i bite the bullet, get myself a new frame and sell it as a complete bike? Do i part it out? OR do i re-weld it. and do a ground up rebuild and keep the bike?
I'd like to race next season and still continue to ride freestyle, also do a lot of dune riding.
Any help would be hugely appreciated!
Cheers guys

Otherwise JGR may have a frame you could buy.
Consider this, it's not possible to get to the inside of the frame and ensure that there are no sharp edges left where the crack once formed after it's welded. Although it might look fine on the outside, on the inside it's very likely that there are still remnants of the crack left, creating large stress raisers that will allow the crack to propagate again over time. That time could be next year, 10 years from now, or it might never progress to the point of being an issue, but that's not something I would want to chance. Heat treatment afterward would also be a good idea, but that's a debate that would get WAY out of hand for this thread.
But that was when it was 4-6 months old too, not sure they would now, I’d look for a frame if Yamaha won’t replace it.
