spider dashboard weirdness

My speedo used to not work (stuck at 10mph or so) then suddenly started working. Great.
Then I noticed that my tach is inaccurate, my ears are telling me I'm near redline and the gauge is nowhere close.
Cluster needs rebuilding/retracing perhaps?

Very common. Typically the potentiometer has gone bad. You can adjust it but it’ll likely just go bad again, so best to solder in a new one.

In the SF Bay Area, Kris’s Mobile Speedometer did a great job to fix and calibrate mine:

Details on tach remove here. You can try the adjustment, but my recommendation is to send it to Kris for a real fix.
