have a 07 FLHR...bought and set up the tts mastertune... went through the v-tune and all is good..my speedo has always been off (slower) by 3 mph..since the bike was new and the TTS has the speedo cal adjustment so I gave it a try but no change, went from 2058 to 2000 ( checked it with GPS)..seems simple enough to set up and Im pretty sure Im doing it right... could it be it dont work on the 07??? or am I missing something...

 

Did you click on "Change Settings" button after you changed the number? You probably need to be down around 1950-1960 depending on the speed you are checking at.

 

Lonewolf, I have the same issue as the previous post on a 2009 FLHR. Any thoughts on what it "should" be set to?

 

Rough guide is to divide your setting by your desired speed and then multiply by actual speed. Most bikes will usually show a higher speedo reading than actual.

 

Will do. Thanks!
