Kev mod ?
 

How would I know if this has been fitted to the bike i'm about to buy. The seller says it has the mod. Cheers.

Get him to show you it, if bike is pre '07 it's a 40mm square box with a rotating switch in the middle, if the fitting instructions have been followed it will be located under the seat, it's wired into a wire using a chocolate block. If it's post 07 i think it should have an 02 controller as well. Search ebay, kev mod for pictures
