lots of ponies = lots of clutching aveneus to explore. Need to start by weighting the
primary with some hefty weights and a nice profile (10-66 arms.) Good stought spring (175-305 ?)
good stiff secondary spring (cat red white or stock yellow). I like a good aggressive helix.
I run a 62-56 in good fast conditions and a 60-54 in heavier wet snow conditions. With
mine: I grunt the hell out of the motor and shift it like crazy, thing literally feels like it is
going to jump out from under you at all rpm and mph ranges. Mine also has pipes, is ported,
bored carbs, gutted air box, cut heads, and 288 of studs, and endless hrs of fine tuning the skid
frame for maximum effiency.
