Sesman:
Good luck with the build, Ash. I’ll be logging in occasionally by satellite to check on progress….something for me to look forward to.👍

When they were new and i worked at Meads we had an insurance job where some scroat undid the 2 headlamp mounting bolts a cut EVERY wire going into the headlamp.
Damn near wrote the bike off with what we had to get new plus had to make the two earth wire nuts inside as Honda couldnt supply

The left hand alloy footrest hanger plate is broken on this project ... lots of RH on eBay but LH hard to find.
My mate bid on one in Japan and won for 200 Yen = £1.07 :)
Also the air filter holder thingy is absent. Laverda Dave put me onto one on Ebay UK at £39 but before buying that one, I needed to see the P.O. in the pub on Monday to check if he still has it, as he had the bike from new. Anyway,I found one in Japan and got my Man-in-Japan to bid on it and won it for 1,000 Yen = £5.40 :). His mate is coming back from Japan in a months time and is fetching my stuff back in his luggage.
I stripped the original style Master cyl. and brake caliper and the alloy parts look serviceable so order repair kits for both and S.S caliper which have arrived already as well as two cans of PJ1 satin black paint. Mater cyl white plastic part was a bugger to remove ... retained with a rather expensive (£6) O-ring .... I also have a spare caliper with a bloomin big allen cap screw tapped into the front face ... presumably to extract the piston. Neat job but just doesn't look right. Pretty sure I saw another one on somebody's post on here recently on a caliper piston body. I also gota pattern M/cyl with the bike in good shape (needs re-painting) but not the standard CB250RS design
I wondered how DK have parts for this model but the Japanese writing on the label on the alloy hanger they have (wrong side for me) gave away that they must also import bikes to break from Japan.
Pics of parts my Man-in_Japan got.

Laverda Dave:
Japan is the place to get the bits Ash if you have the contacts. They had the CB250RZ over there, the tank and side panels were pin stripped and gave it a real classic image.
There was a CB250RSA on sale at Kempton Park yesterday, 18k showing but the top end was covered in oil, looked like it had a blown head gasket, leaking rocker cover gasket and the classic oil weep from the ends of the rocker spindles. He wanted £650 for it but it was rough, full of rust below the paintwork (the paint is very thin on the tank, built to a price). As you have a complete, brand new rocker cover the spindle ends shouldn't leak but if decide to refurbish the spare be careful putting the rocker spindles back in as it’s very easy to tear the very thin O-ring on the end. Triumph unit twins had the same issue and you can use a special tool for those to seat the O-Ring without damage, probably worth making one up for the 250 as its only a bit of hollow and tapered tube.
Did you get the main stand spindle out in the end? I used heat on mine and it eventually relented. From memory I don’t think Honda fitted a grease nipple on the tube (cost cutting again) so probably worth doing when you put it back together.
The front brake calipers come up often on ebay, I dont know if it was used on another model, I think it was made by Tockio and not the usual Honda Nissin. Are the four rubber boots intact and not split, if they are you can get them in an overhaul kit.
You are making a lot of progress very quickly, it could be on the road by Christmas Day :)

The kit for the Tokico caliper came with all of the seals/dust seals/bleed nipple Dave. I just intend to use all of the NOS top end parts .... somebody has gone to a lot of trouble and expense to fit everything to the head and rocker cover even a NOS inlet rubber and valve decompressior mechanism. I noticed there were quite a few of the Hondastyle nose fairings for sale on Yahoo Japan .. even a NOS in bag one. Mine had a fairing (not sure what style) but the PO said the screen got broken .. he still has it and said he will dig it out for mebut TBH I probably wont fit the fairing. Thanks again for your kind help with this bike!
