Frame/Headstock reinforcement drawings needed

[scuderia]

Searched around but most links and attachments are dead. Wondering if anyone has the drawings for the factory (or if there's something even better) frame mods. Also is anyone selling precut gussets etc.? thanks.

depends a bit on which frame we are talking about. looking at your footer, I assume it is for a type 1 triple frame (non RGx frames)?

I ask because there was only ever - afaik - a factory set for the RGx-Frames. OCT has these, they welded it to my RGS 1000 SFC

I have a drawing somewhere with dimensions for that factory kit. If needed, I can try to find it and scan it.

I hope the attached helps.
All the best, Hag.

Bit of a mix - 180 and RGS frames, but gives you an idea

And this may be the most useful from an old post by Red that got mangled on the import from MSN.
His comment was "Have braced the headstock on this frame, actually do it to all the triples that come through our workshop, normally find that most of them have downtube cracking. We just do a simple fix that has seemed to work so far, just weld a plate across the bottom. Other people on the site may have other ideas on this."

these days we send a rolling chassis across to the local frame guru called Dave Kellett, he welds up the cracks in the downtubes, installs a section of rectangular RHS cut to shape, straightens the frames and sends them back to us

once they are cracked/fractured they have to be fixed, but much better to do it before that happens, although it must be said that the few that I have done, more 180's than 120's, is that I find the ignition on the 180's clashes with the re-inforcment and that just HAS to come second, fix the frame first (preferably before fracture) and sort the ignition second, the last one I did was getting absolutely everything replaced as 100% stock, it was a jota, and so temporary bracing was fixed and the tubes were cut right through with a 1mm disc and welded back with full penetration, ( 2 runs, root and filler done with gas) but no added gusseting, I told the owner that he cannot grind off the re-inforcement, but concours builders..............?????

Thanks, yes series 2 jota or mirage frame. Haven't decided which one but suspect they are identical.
Considering building a track only bike.

yes, late 1000 180° frames are the same as 1200 frames

just recognized you are in San Francisco. there are several Laverdista in California, one is Richard K. in Pacific Grove and another Richard a bit north (45 minutes I think). Hope to be back in your part of the world after the infection numbers go down and boarders open again, I just love the bay area.
