Getting back into the rebuild now after Christmas.
Front forks fully assembled. I had the stanchions ground and chromed by Philpotts, repainted fork bottoms and rechromed top nuts.
I also took the front brake apart and had this blasted as it was in a pretty sorry state. Just ordered some PJI gloss black engine enamel ready for a repaint.

First day of my week off and spending it on a self catering holiday in the garage to rebuild the CB250RSA  :).
A very good day today, I have a rolling chassis with rebuilt wheels, repainted frame, reground forks, new seals, replated nuts, bolts and spindles.
The new rear shocks don't actually fit, the upper bush is too small so the old shocks are fitted for now.
Piki's decals should be here soon along with the paintwork from Menno.

Some more progress over the past few days. Rear shocks now fitted (Tec's), front brake fully overhauled with new stainless piston, black coated stainless hose and new master cylinder (old one was leaking badly and pretty rough). Carb ultrasonically cleaned and rebuilt, all new cables. Just begun installing the original loom, lucky enough this was in great condition and came up like new after 65c dishwasher cycle! 
The black plastic trim and rubber parts came up a treat after a good scrub and few days soaking in auto glym rubber restorer, thanks for the restoration tips everyone.
Hopefully it will be ready for a trial start up over the weekend.

Slightly off topic but I remember an insurance job where some scrote undid the headlamp bolts on an RS and the just cut every wire going into the shell, damn near wrote the bike off and never could get some of the special washers/collars---had to adapt what we had in stock but owner was just glad to get it back

I think it was one of your previous 'top tips' about placing the loom in the dishwasher. Came up like brand new :).
The same tip also works for the rubber parts followed by a good soaking in rubber restorer for a few days.
I did have to run the dishwasher empty afterwards with a dishwasher cleaner to remove evidence I had been using the kitchen appliances for motorcycle related activities  ::)
