Very interesting post, especially the part about the ST4. I had an ST4 for awhile and my S didn't stand a chance of keeping up with it once the Duc got above about 6000 rpm. I dyno'd the ST4 and it was making 107 at the rear wheel.
Since I haven't been happy with the supposed performance improvement of my Remus Race exhaust with BBP chip, I think I'll try your setup. (The only improvement has been the sound.) The only thing I don't have yet is the snorkel.
Thanks for the data and the suggestions.
