    Greetings,

    I'm not sure if this is the right location for this question, but here it goes:

    I have a 1997 Sportster 883. The other day I hit the throttle hard and noticed the speedometer needle jumping all over...roughly 20-30 mph range while accelerating. As soon as I leveled off the speed, the needle stopped jumping erratically. Any idea what would cause this?

    well, this is just the factory speedo, so I think it is electronic. Thanks for the info.

    Haven't gotten to it yet. Maybe this weekend....

    Never owned a Harley before, so I'm not sure where it is.

    I'll have to dig out the service manual.

    That's a good idea, not sure on sporty but on the big twins its on the top of the trans held in by a single allen, it has an o-ring so remove allen and work the sensor out, wipe with paper towel and reinsert, then pull back out and reclean it will probably pull out more stuff.
