I am enjoying my 1999 TBS immensely but the more I ride the bike and explore the mechanicals of the machine, the more questions arise. First and foremost, who in the hell designed that double trouble airbox? I have ruled it down to either a frustrated dyslexic engineer or the Anti-Christ. I spent some of the weekend with my Haynes manual and wrenches seeing how the whole thing is set up. On my prior Hinckley Twins and a current Rocket III the first things that found a home in the storage shed was the stock airboxes and of course, the AI systems. Currently my TBS is running 3 into 3 D&D's with what appears to be the stock air filter and boxes. I surmise the jetting is stock also, but I have not pulled the carbs to confirm this. The bike pulls like a train with tons of torque but fades before reaching redline with popping on decel which I understand is a character trait of these models. I have been through all of the set up info here on the site and I am really on the fence about doing away with the airbox and going pods or modifying the stock system with some increased air flow with appropriate rejetting either way. I would also be interested in how folks who went the pod route maintained the perch for the side cover top pins and seat release lock if you do away with the secondary box. To add to the mix, I really like the stock appearance of this motorcycle and pods do impact this. Finally, does anyone have a list of what header systems are interchangeable on the TBS to either do a two side set up or two on one side as I believe was original on the 99 model. The D&D's are ok, but I would like to look at some other options. Thanks in advance for any input from those of you who have found the "sweet spot" on these classic machines......
