so in this thread, dude says dad is having him cut the neck off a "bad" frame and attach it w/ the VIN to a "good" frame
now i've already told him it was illegal and whatnot

the question is would you ride a bike w/ some hack welding the neck of a bike together outta his back yard?
if hes a talented welder itll be fine. but thats stuff you dont talk about, you keep that shit on hush hush.
yeah, it's not like the neck/frame is an integral part of the bike or anything........
ull argue the fact til you die, theres no limit with metal work man.
ok, you risk your life on it brutha.

There are capable welders out there, but it's not the ordinary Joe that's for sure.

Yep.
Most bikes already have a welded neck, it's not much different.
I also ride on plugged tires.

That bike looks old school. An no I wouldn't ride it with a re-welded neck.

and they are also assembled on a jig and welded for precise angle, vs a hack w/ a grinder and welding rig in a backyard.
how can you be sure the angles are correct afterwords and the weld quality, hell zuki had to call back frames cuz they flubbed.
it's like a 96-98 ZX9R

This thread title made me thing of a friend that had to get out of riding because he had a fusion done on his neck. Made it hard to turn his head to check blind spots. So I would say yes..If you have to have your neck "welded" you should not ride.

I'm with you on this. A skilled welder, sure. But a backyard hack, no thanks.

Yep agree with this. I'd also be more inclined to do this if it was a cruiser type but less inclined if it's a sportbike that I know I'll be riding harder.

Um......let's get real for a moment. How are you going to guarantee that the edges of the 2 pieces are aligned properly, resulting in a factory-straight frame?

Eggzacharry. Just a tiny bit off, and the rake/trail, and worse parallelism of the forks to the frame can be seriously 'off'. And without some precision 'jigging', it WILL be off. 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.

Tack on a temporary jig, cut it off when you're done.

Isnt aluminum very tricky to weld in the first place?

Yes - and under/over-penetration (giggety) is hard to control without a good rig (pulsed-DC MIG or hi-freq AC TIG) & knowing what you're doing.

Yes, any hobbyist probably wont have the skills or equipment to do it on their own and do it correctly. Aluminum is very tricky to weld, and most hobbyist wont be able to weld it without warping it. It also probably wont be structurally sound.
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. :tremble:

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
11-16-2009, 01:13 PM
Yeah - that will look legit......
Wonder how that first inspection will go? :lol

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?

Some one post up the pic where the guy rode with no rear axle spacer. That guy would probably ride any torn up bike.
