Welcome back Muzungu; what was your old handle? Thanks for the dissent from the party line. Creeper was pushing it pretty heavily up there... JK, thanks for the clarification creep, I will arrange your facts into a tidy little mess inside my head and when they come back out you will hardly recognize yourself! So some like modifying the top of the airbox eh? Well with most saying the BST likes a "tuned" airbox I worry just how much and where the airbox should breathe. They say the BST needs some constriction up front; the FCR doesn't care about that and can be wide open. Ya see I am interested in improving power ONLY if it does not sacrifice fuel efficiency. I think the bike is powerful enough in some RPM ranges and just needs some tweaking to get it smoothed out in the low RPMs and open up the top a bit. I am interested in the SXC exhaust, but wonder if an unpacked exhaust (metal baffles) would be better (i.e. no maintenance) for adventure touring, like the IDS2 or Remus. BTW, Y'all get better gas in Africa Muzungu? That is a surprise! raipti, send me your mailing address (PM if ya like) and I will ship them off!
