Awhile back lap top i was using went south. Lost stock tune to bike. Called the place that i bought the bike from and they have no record of tune installed and no sticker showing tune download on ECU. So i was wondering if anyone knows exactly what tune Truimph used during the time frame of the 2015 rocket roadsters. Am coming up with stock tune 20773. Did they use more than one tune or is this correct. Any info you folks know of would be great.
