Tach is possessed!!!
I don't know what to say other than my tach reads exactly what IT WANTS to!!! It seems to be worse when the car is cold but it will still jump to a higher RPM seemingly whenever the fancy hits. Oh the only other bit of info I can think of... when it freaks, it's always to a higher RPM. I'm going to check out the level and make sure its correct tommrow, but if anyone has an idea HELP!!!!!!

Does your engine jump to higher rpms too or just the tach? I know if you have indiglow gauges the face for the tach tends to puff up and hinder the needle from moving freely. this may or may not help, but I tried.

- test the sensor input
---ECU pin 53: 0V -or- 7-9V while ign on, engine stopped, front wheel is rotated
---Speed sensor connector pins a/b: merry go around on/off as front wheel is rotated
- Take out u instrument assy and try to find the reason for short. If u cannot find out, install a analog voltage gauge to the wirings coming from the sensor; if no problems there, the short circuit is in the i-assy.
try diggin more from here ...............↓↓↓

Also the solder points sometimes get loose on the pod. If you dont feel like messing with that buy a used cluster from a junk yard and change the tack only. I had something similar to this in my speedo, i tested everything and it seemed ok, but i changed it just to be sure. lo and behold problem gone.
