Default Cbr f2 jetting

Year: 94
Location: Ohio
Elevation: 700-1100 ft above sea level
Temperature Range: 45 to 95°
Air Filter: k&n
Jet Kit: drilled oem keihin jets
Pilot Jet: #40
Main Jet: #140
Needle Clip Position: raise needles 40 thousandths with washers
Fuel Screw Setting: 1.75 turns
Exhaust Type: supertrapp adjustable with discs
Exhaust Modified: no
notes: bike runs silky smooth now. No more light stuttering at cruise speeds thanks to pilot system. No more gurgling when holding it between 5000 to 7500rpm range with raised needles. Pulls harder with bigger mains no longer picks up when throttle cut to 80%. Still somewhat lean if I run this combo with no end cap (basically glass packed straight pipe). Runs great with discs tho, increased torque noticeably!
