Welding vs a new frame?

[pete-blen]

Yip, weld that shit. Because of the action pushing rather than pulling on that bit, it's gonna be fine.

I have welded lots of cast alloy... It's main prob is it can be dirty shit..may have to weld twice..first time to burn the crap out..
then grind most of the weld out.. then re-weld...
I would toss that lug & make a new one from someting like 6061 sheet alloy that raps around the bar more to give more weld area..

Me too. And agreed, I'd do the same.

Yep, I was thinking if you could make one from a bit of 90 deg angle, you could run a nice deep fillet top and bottom....

Have you got a pic?
Even without seeing it though, I'd still say I'd weld it. It still has one good one on the other side that will probably do the job on it's own anyway. As long as it's ground right out and done properly I doubt it'll be a problem. I'm pretty sure there will be places to reinforce it a bit with some extra weld too.
Most cast parts of the frame are welded to extruded bits somewhere, so we know they can be welded.
Why be scared of welding cast ali...it's already been melted once at least...

edit: "look properly dick...there's a pic already."
Ok...I'd definitely weld it back together...looks like lotsa room for reinforcement. Though it'd be tempting to make a new bracket out of some flat instead...less likely to break again.

I have a professional welder coming over today to sort out something to do with it. Cheers for the ideas.

Isn't it more of an up/down thing?

ninja edit: I think its up/down but while it's being pushed in

Again, something else to discuss with the welder, cheers!

I"m having a hard time picturing this.

Or should I just sell it and get a Bros?

This would be ideal

No, they're all for me, find something else

Oh no ya don't! I've got yer frame remember? And I'm goin to use it all for myself, it's being held ransom!

I often hear of people who think the SV is good at the time, then end up finding it too beige after a short while, so it might well be worth considering resale even if you currently don't think you'll sell it for 6 years or more...

Well, there's nothing "wrong" with an SV. They just become very, very boring I reckon if you had one with a decent sounding can and some sexy suspension (non-snapped) it'd be a great bike.

Won't you have to re vin and Reg if you use the other frame?

Just bog up the new chassis number and etch the old one in, then rivet the VIN plate from the old frame on
Totally legit... Well, it should be, it's the same fuggin frame money grabbing mumble mumble grrr

Well, I guess you can use it as a mirror for a little bit anyway...

Exactly, they're like some sort of sneaky beige ninja (see what I did there), on paper is fine, so they sneak into your garage, then one day you wake up and bam, realise it's just too beige.

Legallity wise, I'm pretty sure modified frame/suspension mounts needs certing too...

As opposed to a crashed Kwaka, painstakingly rebuilt into a damn sexy machine but never gets ridden in favour of a GN?

Or said GN that will have a 1200 engine in it before the year is out because it's owner is a lunatic?

I like my twin thank you very much.

Funny, I think the same thing. And I do have a sexy can and (semi)decent suspension on it

doesn't sound too hard....

I've been doing that fucker is a mission to do though

Bit like my CB400 then... damn that was a good bike.

Err... umm. I don't quite know what to say? The Kwaka gets used a wee bit currently

Certainly a better bike than a Hyocunt.

Just don't tell anyone

Wat. Damn.

Alright, never seems to get used. You know what I think I meant to say.

Certainly a better bike than a Hyocunt.

Agreed. It's just their salesmen are so friendly.

At a guess I'd say the shock (or is it the linkage?) plus the two washers didn't fill the space correctly. Hence snapping off the mount before final torque was reached. If you get it fixed, I'd say you want to check the distance between the lugs and make sure it's a snug fit (possibly have a spacer/washer made to suit). Otherwise you may end up snapping the other (good) side off too!

The linkage, where it mounts to the frame.

That's a very good thought with the spacers. I'll definately check that.

edit: Yep. Held the lug in place and put the linkage in between. About 2-3mm of movement sideways which is completely stopped by the two washers that go with that bolt.

Just to be a pedantic prick, the part that snapped off is the 'dogbone' mount. To those in the know anyway.

The linkages are the two flat plates that drop down from the swingarm, to the other end of said dogbone.

Might help save some confusion some time. Also handy if you are searching for a differently offset one to change the rate of shock speed rise...But ya really wanna know what you're doing before ya think about doing that.

I thought the linkage was the bit the shock connected to & the dog bone
were the bits the connected the linkage to the swing arm... DOG BONES because they
look like dog bones...

just type "motorbike dog bones" into google and see what comes up...

Some bones connect to the swingarm, some to the frame; some thigh bones connect to the hips bones, and hip bones connect to the boning bone, wait, that might not be how it goes

Anyway, if he broke em by tightening it up, it probably isn't dog bones in plural, sometimes its just a single bone, and sometimes its the rocker link thingy (whatever its supposed to be called).

[carburator]

failing welding it just drill and tap the frame for a rose joint..

There's your answer to how it snaped i would guess.

You had tightened it up without the washers in and cracked it and diddnt realise untill you went to tighten it next time useing the washers and cos it was already cracked it snapped.

I would be giving the other side a good check to make sure thats not weakened.
