Speedometer Needle - Bounces til 30 mph
I replaced the inner cable with a new one and lubed it with dry graphite powder. When I take off from a stand still the needle bounces in 10 mph increments until it hits about 30 mph - then it becomes steady for any higher speed.
Does this sound like a speedo gauge problem?

Ah. If you're positive you don't have cruise control (single cable that goes directly into speedo) then I'd say you're probably right about the speedometer. I'd still run the cable in a drill to verify it wasn't a transmission gear issue.

It is not uncommon for either the cable side (little square hole) of the driven gear in the transmission to round out or the teeth on the drive or driven gear to wear out and cause the needle to jump at different speeds. What transmission do you have?

It is always better to replace the cable/housing assembly, running a new cable in an old housing just works some of the time the symptom is a low speed twitch. When you lube the cable lube the lower 2/3 with a light lube, vaseline would do. Lubing the top 1/3 section may let the lube travel to the speedometer speed cup. Always clean the cable before lubing well with a fast drying cleaner, carb cleaner will do. Check the cable for any bends/kinks, especially near the top.
