Zephy Servicing (long)

    Dunno why, but I never touched any of the CB's mucky bits with a spanner,
    but with the Zephyr I seem to have had no qualms at all about stripping bits
    off it. Anyway, yesterday I mainly:

    Changed the oil (old stuff was not at all bad)
    Changed the oil filter (no apparent nasties in the old filter, and no leaks
    upon reassembly)
    Cleaned and gapped the 8 plugs (they are bloody tiny, and were a bit sooty)
    Changed the air filter
    Lubed the chain
    Fitted new mirrors
    Fitted the replacement twist grip. Now this was a real slag. I treated
    myself to a new Draper soldering iron, so the first job was to snip off the
    nipple I fabricated during last weekend's fuckupfest, and solder on a new
    shiny brass one. So far so good. However, upon reassembling the twist grip
    mechanism the bloody thing would not spring return with both cables (push
    and pull) connected. It worked fine with just the pull cable however. I
    considered leaving the push cable off (why is it needed?, I cannot see any
    point to it), but decided it must be there for good purpose, otherwise Mr
    Kawasaki wouldn't have made his nimble fingered mechanics install the bloody
    thing in the first place. Any way, after much fucking about I espied the
    small metal pin like thing which goes through the back of the twist grip
    assembly. A gentle tap to move it a bit more "in", and it works fine (no
    mention of this in the £45 genuine Kawasaki workshop manual I purchased
    either, which is a bit of a pisser).
    Oh, and finally I sold the Honda to a nice young couple, it's for the wife
    who is shortly upgrading from a 125, so whilst I am a bit sad to see it go,
    it does seem to be to a good home, so can't complain, and I got £1950 for it
    (it only went on Bike Trader webshite on Friday).

    Also, any idea why the NSR seems to piss petrol from a rubber tube at tyhe
    bottom of the belly pan whilst parked, it's fucking irritating, and the shed
    now reeks of unleaded.

    Oh, and I have a race can for a CB500 going begging, which I may ebay when I
    can be arsed. If any UKRMer wants it, it's theirs for £65 if collected or
    £65 plus carriage if posted (s'wot I paid for it).

    Finally, at the end of the day yesterday we had all 4 bikes out the front on
    the green. Having had a frustrating, but ultimately rewarding day's
    fettlement I remarked to my boy that despite getting a bit pissy with it,
    the Zephyr still is (IMHO, natch), a damned handsome looking motorcycle.

    Glad to hear you replaced the mirrors... was looking a bit sad before wasn't
    it.

    £1950 was fair enough for the CB, by the time you sell your can you'll have
    your two grand.

    Classical symptom of the carb overflowing due to a stuck float chamber
    valve (usually caused by muck in the fuel). Take it out and inspect the
    rubber tip - if it looks "stepped" it's time for a new valve.

    Another - more expensive but less likely - possibility is that the
    floats in the carb are leaking. Because leaky floats take on liquid and
    lack the former buoyancy they don't close the float chamber valve
    anymore.

    Both result in the carb bowl overflowing when the engine is off.

    If the NSR has not a "normal" petrol tap but a vacuum controlled item,
    check the membranes in said tap as well.

    Cheers Tom. As the bikes still under warranty I may just let Honda deal
    with it though. Seems that turning off the fuel tap stems the flow though,
    my lad reckons he's read somewhere that this is a common problem with NSR's.
