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  ::)

Good progress today on my day off. All the wiring is complete and surprisingly everything worked and I had a big fat spark. The front and rear brakes are now all set and adjusted with the biggest job, fitting the pattern exhaust also giving surprisingly few problems.
I've also added some non-standard chrome bling with the kick-start and rear brake levers.
All that is left to do now is fit the paintwork and run it  :)

Looks really good,  I've always liked the style of those and nicely offset with the spoked alloy rims. A good looking bike.

Quite a few of them used to hoon around in London on courier work if I remember correctly. Seem quite tough little engines.

That looks ever so good, makes me want to get out into the garage and get stuck into the F2.

I'm sticking with the original blue Julie. I was going to change it to red but I've had enough red bikes!
Menno had a few problems obtaining the exact match but these are now overcome and he's in the process of completing the repaint. Piki has made the decals and sent these on to Menno.
I can't wait to see the finished result and neither can the O/H as it's going to be her bike :). Hopefully we'll get some miles in over easter.
Thanks for the nice comments Spitfire, the snow's gone and the temperature is nearly tropical compared to last week so your garage is calling for you  ;).

Hi,
Is it someone on here that has made your logos ? I can see a couple of firms on ebay do them. Do you know anything about these or the quality. I will be redoing mine in the original cosmo balck.  One problem I have is that the blue on the middle of the tank is not listed by honda. Only thing I can think of is to buy a logo set and then get those matched to paint. Or even paint all the blue bits.
