Just a heads up, I bought one of the Drag Specialties tachs for my 2010 America (efi, elec speedo) and it works only showing 50% rpm. There are/were major electrical changes that year and the tach does not work as it should.
The often used ecu connection on older bikes is not there on the 2010.
Great tach where the application will work, looks good and nicely lit.
One side benefit, my math skills (at least the 2X ones) are used often.
