Carl, thanks alot for the up-date on the new direct drive Valvola. It will be interesting to see what change the new drum set-up makes. The tri port exhaust isnt anything new. RB Concept .21 motors did that exhaust port layout back in 97. Richard D
Maybe RB copied CMB then because I ran a CMB triport exhaust 21 in 1995
