Also since Springfield, Yoshimura had completely gone through the official CW Honda CRF450DT'R; $2800 worth of engine love that included a top-end port/polish and a new cam ($499). And, our transmission was treated to an ISF physicochemical process—a sort of vibratory massage using high-density non-abrasive ceramic nuggets that remove surface asperities and microscopic imperfections for reduced internal surface friction. We were also sporting a new stainless dirt-track low pipe ($1350) with Data-box self-mapper bung ($429) that plugs right into a PIM-2 programmable ignition unit ($339.95). Cosmetic speed enhancements consisted of a Lime Nine graphics kit ($198) and some Spider grips ($17) and red CV4 silicone hoses ($198) that had me craving Twizzlers. Furthermore, Southland Racing Products revalved our shock for less stiffness after Springfield, a change for the better at my local SCFTA track, too. And so, we unloaded the CW van in the Sacto infield with boosted power, a sweet chassis and great expectations.
