Default Tachometer needle bouncing

So for some reason lately my tachometer constantly bounces when im driving my bike and i feel it and can hear the tone of the engine going up and down. The movement is very small but it isnt a smooth ride and im kinda of worried. Any one out there have any idea why it isnt giving constant power to the engine, maybe bad fuel injectors or a loose throttle cable??? anyone have any suggestions?

Sounds like a loose ground, or bare power wire going to ground somewhere. Check the battery connections, then inspect the harness and the connectors. Could also be a bad plug or bad fuel maybe contaminated with water.

Had same prob recently and turned out to be loose batt connection. Would idle fine and everything but riding rpms would fluctuate. Check batt. Ya never know.
