Justpicked up an 07 s4rs with 3400 miles.stock except arrow slip ons,It seems a little sluggish should it have been remapped?
Congrats! Pics of your bike must be under the general tab. :)
I can't comment about the remapping, but adding exhaust to my 1100 did not help out the tall gearing. A 14t front sprocket for my 1100 and my 696 was a quick, cheap fix for me.
Yes,
an S4RS with slip-ons needs either a re-map or the DP ecu.
