In truth, the Air Box removal & installation doesn't even need any instructions. I did the BellaCorse version over the weekend & it is really straight forward. I was afraid to order the kit because removing the side panels & looking at all the garbage attached to the stock box really made me uneasy. I had to buy a Torx bit set, as the set I had lacked the correct size to remove the rear fender. (Triumph really likes to use the thread-lock!) I bought Sears # 46703. I removed & replaced the box & fender in about 45 minutes, removed & replaced the stock mufflers with EMGO's in about 30 minutes. Since I'd had bad luck in the past with stripping screws on float bowels, I took my carbs off & took 'em to the dealer to re-jet, swap the Phillips screws for the included Allen style, & replace the 'D' screws with the thumb screws. It cost me one labor hour with the dealer, (some here may think me a poseur but I'm glad I did it that way.) I Put the carbs back on Saturday & it runs SUPER!! No issues whatsoever, runs just as well & reliably as stock, (road about 100 miles over the weekend, & in to work today) but quicker & LOUDER. :-D I'm by no way telling anyone which they should buy, I'm sure all the kits are great, I just sat on the fence debating my ability to get it done & not screw anything up & sacrifice the reliability, ride-ability & enjoyment of my bike. Go ahead & do it, you won't be disappointed!
