Yea I noticed! Actually all the gauges work great EXCEPT the speedo!
So I installed the filter like they said, and now the gauge does very little. After a bit it did swing back and forth a few times, peg out at 120mph, swing back and forth and then go right back to 0. Wouldn't even let me do the calibration, just went back to the odometer after 5 seconds!
Yea, I think there might be something wrong with the gauge.
But they look really good!!!
