i am installing an air shifer with a small bottle that fits perfect where my tools go under the rear seat. i have a power commander that takes up the rest of the space. i have an air compressor that i cant find anywhere to put. im not really worried about that because i have it to where i can fill up the tank pretty easy. i plan on putting nitrous on the bike within a couple of weeks. i need to find a place to put it where no one can see it. where are you guys putting your bottles?
