Moxey:
I ended up getting the steering stop, gussets and front down tubes welded by my in-law (stick welding big lumps of metal I'll have a crack at but thin tube I'll leave to the experts!).

No photos after the welds before I took the frame, swing arm (sans bushes) and stand off for powder coating but should be apparent where gussets were (headstock tube to spine, swing arm pivot point and rear frame).




SumpMagnet you asked about VIN plates and Painting in your thread, I opted not to risk damage to the original (my painters advised against leaving it on from past experience) so I drilled out the rivets and put the heat gun on for a few minutes to soften the glue, my original was a little scuffed anyway so I purchased a replacement plate from http://www.vin-plate.co.uk/ and had it engraved at work (a trophy makers or equivalent should be able to do the same) going to rivet it on this weekend.

Fitted new headstock races from All Balls




Achieved with home made bearing press (old bearing and threaded rod)



I also pressed in replacement NOS shock bushes in the swing arm.


I also fitted needle roller bearings in the swing arm (I considered bronze bushes but time constraints and finding a reliable supplier led me to the easier option of the roller bearings from WeMoto).

@Oddjob I purchased on recommendation from some of the members on SOHC.net, is that a recent development or has it always been the case? Unfortunately already fitted as you can gather otherwise I might have sourced alternatives but no bother the front end is easy enough to work on.

Nurse Julie:
If your swing are roller bearings fail, which I hope they don't, I always have stock of the bronze bushes.

SumpMagnet:
Thanks for the VIN plate bit...plus from what I was advised in my other thread, I think I will go that route too. With lots of pics to prove it's legit.

Curious about needle rollers for the swingarm. Is there any advantage to phospher bronze bushings? Needle rollers is what I am used to on bikes, though I also know what happens when you neglect them. Bought a Gpz1100 'with a fresh MOT' and a swingarm that could be pushed into the footrest hangers either side. Bearing cage was a goner. Apparantly...it handled OK. Sheesh.
I am sure I spotted a grease nipple hole on my swingarm. No nipple...but a clear threaded hole where one would go.

Bryanj:
Needle rollers are fine when they are rolling(hence the name) but don't do too well when only moving through a small radius. having said that keep them well greased( 1,000 miles MAXIMUM preferably weekly) and you will be OK for quite a while

Rob62:
Nice work.... If anybody wants any 3D models knocking up for cad/cam machining etc just let me know...so long as you know the dimensions i can create the model.
