    First valve adjustment at 16k miles/24000km

    Hi! My bike are soon to reach the 24000km (16 k miles). And time for the first valve adjustment/inspection. How many of you have done the first check and really had to adjust? Or has it just been a job just to confirm that the clearance are within specs?

    I'll be out on a long journey when my bike reaches 24000 km, would i be necessary to do the adjustment before the trip, wait until I get home or just skip it (until next 48000km) as long as the bike runs smooth?

    Thanks in advance.

    Excellent question without a simple answer. The V4 is SOHC..single overhead cam.
    The intake valves are under the cam and are surrounded by a bucket. Bucket unders typically
    don't wear as fast as the rocker arm's do. Your exhaust valves are under the rocker arms. In order
    to adjust the intake clearance, the cams have to be removed and reshimed....ugly. The intakes are far
    simpler and only require a spanner.
    If you are the type of rider that likes to rev your engine up and keep it close to red line then you
    are probably putting significant stress on the valse train. If not and your engine is running smooth and
    there are no unusual sounds coming from the engine I would say go on your ride and don't stress to much
    about it. Take it in for the valve inspection when you get back...
    One caveat, How hard nose is Honda regarding preventitive maintenance and your warranty? Maybe a call to
    your Honda dealer can answer that question or maybe some of the members of this forum have some experience
    with that.

    Hi,
    It is important to inspect valve adjustment, regardless of the make of machine. It is also important to check at the first interval from new as all components have to bed in and what was adjusted correctly at 0 klms may have changed after 24000klms.
    It is also a great feeling when they are inspected / adjusted, that all is good with the internals of the motor ( when it is combined with a service)
    I have had them inspected around 24k and the mechanic said 2 exhaust valves were out of tolerance.

    Around 24 k klms is ok. It is not just the feeling of smoothness but the precise timing of valves, ease of starting,emission control, oil usage and fuel consumption that are affected when they are out of tolerance.
    It takes about 7 - 8 hours to check when combined with a service, so its pretty labour intensive.

    OK Thanks! I'm very gentle with the throttle, traveling long distances (northern Sweden, I'm able to travel for 20 minutes sometimes without meeting a single vehicle) at even speed and low revs. Warranty ends in less then1 month. So I feel pretty confident to wait a little bit and a few "over miles" (pardon my lack of english skills) probably wouldn't harm my bike to much.

    You'll be fine, go out and take a ride and have some fun, I hear all Swedish girls are a 12 on a scale of 10.
    Is that true?  :156:

    Installed my battery this weekend (still zub zero degrees in nothern sweden) just to find out that I haven't reached 10000 miles yet  :431: (15558 km). So I'm able to drive 6000 miles more before any valve adjustment. Well, still "good-to-know" info anyway. Thanks for your replies
