Sorry I haven't replied...been on a dual sport ride in the Ozarks.
Denase - You don't have to buy an RT cover. Just trim your GS cover at the "step" on the spool. This is what I did and it worked fine.
rdcyclist - of Motoradd deleted the VSS then what feeds the speedometer a signal since there is no speedo gear and cable like on the 1150?
I am about to install another of these on a friend 2006. I will take more/better detailed photos and do a complete documentation posting it here. Of course like RD says it the VSS portion may not apply to 2010 and later models.
