SnowTech reader Greg Ankofski provided valuable information in regards to installing a set of Boyesen reeds into a Rotax Series III engine;

“Just got done reading (in the March issue) about the guy with the 2005 REV 600 using Boyesen reeds having the bogging problem. I know from first hand experience that Boyesens in that sled will need a RICHER pilot setup to account for the added air flow off of idle (compounded by reed spacers, if using them, which reduce the carb signal). The area where you go leaner is for the main jets (one size leaner). Switching to #20 pilots and 2 turns out on fuel screws solved the bog problem off idle in all Series III BRP motors when using Boyesen reeds.”
