    Hi all.

    I'm keen to have a crack at checking/adjusting the value clearances for
    my Honda Spada. Can anyone give me some basic instructions on how to
    do this? I have read the aritcle written by zeebee a while back, and
    would welcome any Spada specific information that might be of use.

    I was also looking for a copy of the service manual, but I have noticed
    that the website that use to host this is now only shipping it on CD
    (for a price). I can probably host this for free if someone has the
    files handy.

    Cheers, paulc.
    Spada -- still going strong....

    Whathe????

    How long have you had it if you haven't done your valves yet?

    INLET VALVES: 0.15+/-0.02mm
    EXHAUST VALVES: 0.20+/-0.02mm

    They are adjustable by screw and locknut so...
    Allow engine to become dead cold. (leave overnight).
    Remove Seat
    Remove Tank
    Remove Radiator and associated hoses ( or just manouver them out of the
    road).
    Remove cam covers.

    Find Top Dead Centre (TDC) on the COMPRESSION stroke, first cylinder.
    *
    Check clearance using feeler gauges.
    If out of spec, release locknut (8mm hex), then adjust to spec using
    appropriate screwdriver.
    Tighten Locknut to an appropriate torque. Use a little loctite if you
    feel it is neccessary.
    Check clearance again and adjust if neccessary.
    Repeat from "*" until all valves are checked.

    Note that you will need to find TDC on the Comp stroke before doing the
    next cylinder valves.

    Happy to help.

  6. Watch the valves. It goes, as they say 'squeeze bang blow suck' - which
    expanded out goes:

    (BDC) squeeze (TDCcompression) bang (BDC) blow (TDCexhaust) suck (repeat)

    At the top of the compression (squeeze) stroke, both inlet and exhaust
    valves will be closed, and will have been closed for a while and won't
    start opening for a while. At the top of the exhaust (blow) stroke, the
    exhaust valve will have been open and will be closing, and the inlet
    valve will be opening and will stay open for a while.
