    On my 1998 VFR800, sometimes I get false neutrals or missed shifts (usually false neutrals) when I shift from 1st to 2nd, or 2nd to 3rd. I know from experience that Hondas have somewhat clunky shifting (years ago, an old buddies 1987 & 1989 CBR600 had a loud "CLUNK" as he shifted), however does anybody else have this issue? Any recommendations? I have tried repositioning the shift lever to ensure that I am not over extending my foot to an awkward position while shifting. I run Motul synthetic-blend motorcycle oil. I have had this bike since November 2006 and the prior owner was pretty good to it, though not sure how nice he was shifting it.

    Any ideas or suggestions would be appreciated.

    Thanks,
    Jason

    I have the same issues going from 1st to 2nd on my 02vfr. For me when I wear a heavier boot I don't have the same problem. I think it has to do with the spacing of the gearing. It is kinda tall between 1st & 2nd

    I have a '98 and if I'm not entirely paying attention to my shifts I can get a false neutral here and there. Most of the time its not a problem.

    If it does happen I call myself a dumbass and remind myself to wake-up.

    I would respectfully suggest that technique plays a role here...most opinions state that shifting should be fairly firm. Might also try a touch of pre-load (pressure on the shifter before the shift) and Post-hold (pressure on shifter after the shift) These techniques work well for me, as well as minimizing the throttle dip between gears. My 06 likes me better when I barely dip the throttle between gears...

    I have the same problem. I did it today a couple of times and I noticed it happens less when I first get out on the road so I suspected some of it is me paying less attention to my technique. I think minimizing the throttle dip is right. When the bike is cold or cooler the idle tends to stay higher and there is less rpm drop between shifts. I'll have to watch that. Thanks gunracer.

    I have to agree with gunracer. The key to good clean shifts is the pre-loading the gear selector. We learned that years ago in racing. This applies when upshifting. Preload just short of shifting, then when you are ready to shift....quickly lower the throttle setting and lift smartly. Better yet...get an electric shifter that kills the engine for a microsecond. I rode a land speed record holder (Kaw ZX11) Muzzy bike that had this and it was a blast. Lots of roadracers and dragsters have this feature. It took awhile to get use to holding the throttle wide open and shifting, without moving the throttle. You might also be sure to move your foot forward a bit, instead of shifting with the end of your toe. Let us know if it helps.

    Funny Thing

    I used to get false neutrals on my 99 vfr. I really didn't get them to bad until I hadn't change my oil for a while. I recently changed to a real good oil and I haven't had a false neutral since.

    Or you could shift just below redline every time...those are always smooth as hot buttered silk! :)

    FWIW, I noticed when riding between the 954 and VFR that the VFR needs to have very positive shifts made, no lazy what ever movements here. Quick and to the point shifts seems to be the cure, cause from what I can tell as it's in the amount of linkage travel, The 54 needs not as much to change gears as the vfr. I've caught myself being lazy and she'll let you know thats not the thing to be doing, or when wearing different boots, my new ones gave me trouble till they where broke in, just pay attention and things will be just fine :) VFRs seem to shift pretty smooth, just need to make sure one uses the full movement of the shift lever

    I find that when I go between 1st and 2nd that it will go into N. I guess after reading these post though that I wasn't giving it enough swing. But I hate it when I get into second and the N light comes on ever so slightly I figure its not all the way in gear so I give it more pressure and it goes into 3rd.
