On mine i removed the seat duct and use a uni filter. I tested it both ways switching back and fourth on the road (keeping tools and duct in a back pack) and it runs quite noticably stronger that way with or without custom tune. I just use the stock tors tune these days and it runs great like that.

I was running the BC filter kit before this alteration. My tune is the same, running a bit to the rich side, and if any, I have noticed a bit of a power increase above 60 mph, probably due to a bit of forced induction, from the head wind. The Bird is put away for the winter now, so I wont be able to test further before spring arrives, but to be honest, I did this modification for the looks of it, because i thought it looks cool, not for any power gain.

Rain or water has no influence, but since it is a "nice weather bike", i try to avoid bad weather anyway. By the way, I have never been able to prove any power increase from the BC Kit, but the reason I did run it anyway, is the nice roar it delivers from the intake, due to it being more open. It is somewhat the same with this new setup.

According to B.C., the kit adds horsepower and torque but who knows. I do know my bird runs a bit rich (dyno tuned) and think the additional air will increase performance. ...we'll see. And I'd avoid bad weather too, no fun getting wet.

Spectacular paint job, that must've taken quite awhile and a lot of work. Custom everything, tons of chrome, whatta beautiful bike. Takes a massive amount of skill, knowledge and patience to do so much and do it so well. Wow.

Thank you very much MotorMac, much appreciated, try to do my best, but I must also admit that I am a perfectionist, good enough is not for me, it must be perfect.
You are right though, there no official Triumph accessories available for my bike anymore, so I have to come up with things myself.

Hello, cool setup! Very unique! Would you be willing to sell your BC setup?
