    TOG, I've come across a Honda CB250 K4 and a 350 K4, both 1974, both
    have been off the road for some time but appear to be running and in
    OK condition.

    1. Any specific problems to watch out for?
    2. What are they worth, roughly? Both appear to be in niceish condition.

  2. The 250, in decent nick, is worth maybe 400-500 quid. More if iut's
    really clean and original.

    Add at least 30% for the 350 - it's a much nicer machine and the classic
    racing boys snap them up.

    Probs? Usual Honda top ends. They have a jockey wheel camchain
    tensioner, exactly the same as in the SOHC 750, and for some reason it
    doesn't work well in the 250. Rings, bore wear, - look for smoke puffing
    from the rocker box breather: it's a dead giveaway.

    Bottom ends and everything else is solid. The usual chromework hassles.

    The Older Gentleman was seen penning the following ode to ... whatever:
    Haven't established that yet, unfortunately. The seller appears to
    have problem with another hopeful, so I might be able to snap it up
    next w/e if the other bloke hasn't come up with the cash by then.

    On the positive side it appears to have been resprayed, but the guy
    seems to know them rather well, on account of assembling them when
    they were new. He pointed out that he PDI'd this very bike back in
    '74...
    Hmm. Where does the 'much nicer' bit come from? More power? More
    torque?
    Arrrggghhh. He's used the 'C' word ...
    Ta.

  4. Just that. The 350 is actually 325cc, by the way.

    The bikes are otherwise identical, but the 250 needs revving much
    harder. All the power is concentrated at the top end, above 7000rpm. The
    350 is just much nicer and easier to ride.

    I nearly bought a very clean original 350 at Kempton, a couple of years
    ago. Seller wanted (IIRC) 450 quid, and we were chatting, and he
    admitted he bought it out of someone's garage for ukp200 or so. We
    agreed that if it hadn't sold by the end of the afternoon, I'd have it
    for 300 quid.

    Some sod snapped it up half an hour before closing time. Ho hum. That's
    the way it goes, I suppose. I recall that was exactly how I bought that
    rather nice SR500, when you were around.

    Hmmm. Bit academic now that it turns out the 350 is gone, but I'll
    keep it in mind. Well, I'll see if the 250 is actually available next
    weekend and find out what it's like...
    Aye. Isn't there another autojumble the weekend after next? I might
    fancy coming down, tempted to bring the GT and see if some
    idiot^Wvalued customer wants to buy it....

  6. The 250 really isn't that nice a bike.
    31st January.

    And presumably used 350 engines/barrels, heads and pistons are like
    rocking horse droppings thanks to the racer boys, right?
    OK, I'll keep that in mind.

    Heh. Best of luck. :p

    I've still got a couple of Triumph bits for you... I'll drop in and see
    ya.

  9. Well, IIRC, it's just a matter of boring the 250 barrels to 325cc.

    The crankshaft balance factor *might* be different, to allow for the
    greater reciprocating masses (The Yamaha XS250/400 differ merely in the
    bores, but the cranks are different for this reason) but you could
    certainly live with a few more vibes.

    Hmmm. Tempting.
    Well, *I* probably can't - I had to sell the 3 1/2 because of the
    vibes in the end, just when I thought I could keep it after all.
