Since installing the RapidBike controller and wire bundle, my seat has to really be muscled to lock in correctly. It's kinda buckling aft from all the gear and the position has changed slightly, leaving about a 15-20mm gap at the tank seam. Honestly, my seat always had issues with the forward guides not staying on the bobbins very well. Even after a lot of work on that area it still shifts a little when I ride hard. I think the seating position has changed just enough that I've got too much forward slope.
Oh, I had to ditch that worthless tool kit to get the seat on.
