would you ride a bike w/ a rewelded neck?

I also ride on plugged tires.

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

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.

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.

Isnt aluminum very tricky to weld in the first place?

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.

NO. Btw the guy is an idiot.

Don't be such a fucking pussy.

Jigs. Fuck that shit.
