Here's a Harley Tach.

 

Kinda felt like a retard, but the first 3 days I had my Lo I didn't know it had a tach built-in... was thumbing the trip button and was like "oh shi+" didn't know that was there...

 

yrs ago I found a site that U can print out a chart for RPM VS MPH...

Just fill in Ur tire size and gear ratio's and what range U want and print..

Here's what it is for my 07 Heritage.. Ur 09 FB should be the same I think.

The stock speedo for '11 had a tach in the ODO window.
6200RPM!? Mine hasn't seen higher revs than 3300 yet and I thinks she's powerful. 6200? It can get to that? What is the limit on a stock motor?
I have this now, I love it:

 

I use my ears and the feel of the bike as my tach.
