tach issues
What is the tach hooked up to? whatever the rpms are measured off of i think its loose...reason being, when cruising last evening i was watching my tach to gauge RPMs beings my speedo is off...and while at a constant rpm, it would jump up and down like a speedo needle will do if the cable is loose or whatever. i listened to the engine, and it wasnt surging...
is there anything i can do to tighten it up/stop that?
i dont want to swap tachs.
