Yes, that's the same one Oddjob. I've enquired about the one in the breakers, is the cam OK etc and the reply I got was to come and see it! Like I'm going to travel 130miles to see a potential heap of junk, no customer service at all (angry thread >:(). The other engine has broken fins and missing bolts etc, so not worth it. I have stripped my engine down and it's not looking like it should go in a skip. Needs a crank rebuild as small end is toast (scored).
Ideally I'd like an electric start motor but these are very hard to come by and not very reliable from what I've heard. The dilemma is the O/H really struggles with the kick-start even though it has a decompresser. Looks like I'll rebuild this and sell it straight away to fund a newer CB250 such as a nighthawk or something. I'll add any updates to my original cb250rs rebuild thread.

Graham lives over that way, could he not inspect the engine for you? If he's willing of course.

Am I wrong here but the breakers one is the one with the broken fins and missing bolts, the other one in Spalding looks fine from the outside and it appears he's looked after it. Might be cheaper than getting your old engine working again.

I don't mind a trip to Spalding for a member, only 45 mins away. Always a gamble with any secondhand motor, you can't see inside the bloody things.

Graham, thanks very much for the offer to inspect the engine for me but like you say, it's always a bit dodgy buying a second hand engine. These particular engines are not the most robust either at the top end. I'm just cleaning my engine now, the damage isn't too bad considering. I can get a next up rebore of 0.50 if I can get a piston. I'll get the cam reprofiled by Newmans. The crank will need a new cobrod and I've been touch with the company recommended by Nurse Julie. Only problem so far is obtaining the r/H main bearing, the one with the undercut on the circumference, nobody has one, even CMSNL. A few companies on ebay say they have them but don't answer if I ask if they have the undercut, I suspect they are just plain bearings available anywhere. I'll keep trying, might have to get a used crank.

The RS250 engines were never the best of Honda's 250. You have to get a bike with a Honda KB4 engine next time  ;)

As to why it happened, delving deep into the memory I remember a 400N (twin) that holed a LH piston and I rang Honda dealer Tech for advise. They said that there had been a few worldwide that although the strobe timing came up OK in the workshop were found to have been advancing too far and holed pistons. The problem was the only cure was a new alternator stator that came complete with rotor and in 83 ish cost over £300, when we checked honda parts said that due to better quality control of parts we could order just the stator under a different number for about£180---guess what, when it arrived we got bot stator and rotor for the £180.

Never had a decent reason as to what went wrong with the stators but replacement did cure it and i think the 250RS had a similar ignition system
