Holy shiznit... Has it been that long? My my, how time flies.
It flies.
I have single bus owners who are now parents with kids, I have parents with little kids who are now big kids, I have customers who once zipped around enthusiastically but are at the end of their physical flexibility, nine years of this Itinerary is a Chunk Of Life.

move the spring through the anchor pin to make it either shorter or longer

So the spring is too hard and pulling it away from the zero peg ad also resisting the magnet at higher speeds? :study:
Is the air gap between the magnet and the speed cup within spec?

Yeah, probably too much. Ever seen offroaders reweld broken frames with a couple car batteries and welding rods?

Can't figure that out. It acts like not enough spring at slow speed when it jumps to 20 in 1st gear, it reads 35 at a true 28, it is perfect at 50, but it reads 60 at 63.

I say tighten the spring some, but what about the upper end? Do I reposition the needle to true out at 60, and hope the spring keeps things more kopesthetic lower down?

The problem with all of this is the major disassembly required each experiment . . .
Colin??

No you don't have to disassemble it each time if you make a reference RPM.

LOL Yeah, the Harley adjustment tool.
(The reference RPM with the drill doesn't much matter, by the way, as long as it is in range of the speedo and the same speed reference is used before and after adjustments so you can see percentage of change.)
