Hey guys,

Odd problem. My Tach works great, but my Speedometer is way off. Not your typical 1 or 2 mph, but more like 30% off through the entire range. It does seem to be a percentage of difference vs. always being off by the same value. When I'm doing 50 I'm actually doing 70, haha!

Any ideas? I don't really know where to start since when searching you only find the usual "wrong size wheel" threads.
