YEAR: 2012
INTAKE MODIFICATIONS: Snorkel removed, Uni Filter Panel Filter
EXHAUST MODIFICATIONS: Yosh Full Exhaust, Kleen Removed
JET KIT OR STOCK: Kit
BRAND OF JET KIT: Dynojet Stage 2
MAIN JET: DJ 98
NEEDLE AND CLIP POSITION: 3 from top, then another placed 1 from top, no washers
Pilot Jet: Keihin 42 ordered separate
MIXTURE SCREW SETTINGS: 1.5
ELEVATION: Sea level

MISCELLANEOUS: Went from dynojet to factory pro then back to dynojet. the factory pro was close but the top end lagged no matter what settings, idle and just off idle was terrible with the 40 pilot jet. I would go from 2 turns thru 2.5 and it would fluctuate and/or drop below the set RPM. the 42 is critical IMO.

My theory is the 40 is to much fuel over the air in the mixture, the 42 makes it a better blend at 1.5 turns out. all dirt bike tuners say if its over 2 turns you need to go up one on the pilot.
