Actually Idaho Red the rake is unaffected by longer rear shocks. What is affected is trail measurement. The taller rear shock will shorten trail (that's a measurement of front axle center on the ground to the centerline of the fork leg projected to the ground) and provide faster turn in. The max length you can go to is 13.5" eye to eye on the rear shocks. The shaft drive won't accomodate any longer shocks than that. If you don't need the taller seat height stay with the 12.5" shocks. If you go shorter shocks your trail values get longer and the turn in gets slower, plus you get limited travel so usually a harsher ride with heavier springs to keep from bottoming the shocks. My Bobber's rear shock has 3.25" of travel, the OEM shock with its limp spring would bottom out going over a #2 pencil with my lard butt in the seat.
