Yep....In theory the FXR should do 150mph with her current gearing.

To tune the carby on my wideglide it says to adjust the screws to certain revs, but there is no tacho.
Been thinking something like this might be worth getting.

You might find an iPhone app that can do it. In the end I went with a Zetronix unit to tune and setup the carbby system.
