[Retro Rich]

Baron's Big Air Kit (BAK) is awesome on the X. I installed one on my 1300R and love it (the "flame" version). Comes with everything you need to install it (jet kit, Rain Coat, reed valve block off kit to disable the PAIR valve system). High quality product, excellent chroming, excellent fitment. I purchased mine through Metric Thunder and saved some $$. Do your homework as the price on this differs from site to site; they had the best price I could find out there.
