ha. i just got a new leather spring seat, and it's huge! i now have to do some reworking behind the seat to get it to fit in a laid back position. i had installed a 5.56mm ammo crate and ran my DIY battery kit for my lights and switches into it, but now i think i'll move it down to the side of the rear rack, and go your route with the iron plumbing for the seat post as well! funny i thought of it last night, and then saw your picture this morning. ALSO i just got the CNS v2 carb two days ago... and from stock (adjusting air/idle screws) i can't get more than 15% throttle from it. i'm going to try adjusting the needle clip today... but ugh. if i buy that DAX carb, what the **** am i going todo with the CNS and stock carbs?! i wasn't planning on collecting supplies... hah.
