would you ride a bike w/ a rewelded neck?

On top of that, good weld penetration on aluminum can be a tricky thing, even for an experienced welder, especially without a good hi-frequency DC inverter (welder). I'd guess it was likely done by an amateur, with with a 'hobby' wire-feed welder, and lined-up by eyeball - no way in HELL I would trust it.

I really wouldnt have a problem with it if it were a cruiser with a steel frame though.

Warping will be the least of his problems. Probably half of amateur welders don't know how to read the puddle correctly to make sure they are in the correct heat range. Did he have the correct fillets for a structurally sound weld? How much oversize did he cut the "new" piece to allow for shrinkage?

I just hope it's his own bike and his life insurance is paid up.

NO. Btw the guy is an idiot.

[unknownroad]

Yeah, I'm with most of the others. A steel-frame chopper? If the weld looked like it was done by somebody who knew WTF they were doing, probably. A powerful, short-wheelbase bike with an aluminum frame? No way.

Personally, I'd just sell the extra parts, and use the money to buy a legit bike with an engine/transmission failure.

turns out dude is basically gonna cut an oblong piece outta the neck that goes around VIN #, and cut out similar shape on the "good" frame, and weld the good # into the hole left by the "bad" vin, and clean it up.

Depends on the welder, I would trust some welders over the original weld.

[Kerry_129]

Yeah - that will look legit......

Wonder how that first inspection will go?

how can you be sure the angles are correct afterwords and the weld quality, hell zuki had to call back frames cuz they flubbed.

Don't be such a fucking pussy.

Jigs. Fuck that shit.

Yeah, like the 2 cuts are going to match exactly. And yeah, like someone is not going to notice what he did.

Sounds like a bunch of losers on that board.......Houston Imports? Yeah that's gonna be quality peeps. BTW what's a Trans Am doing on that board?
