1980 Vespa P-125X, VMC Stelvio 177, 120AC/BE4/122MJ, 58/120IJ, Air Mix 2-1/4 Turns Open Ride 1

Upsized the main jet from 120 to a 122 and changed the Idle Jet from a 60/120 to a 58/120. I can feel more power now and the max CHT recorded was 308DegF, 60MPH, 6,400 RPM. This is cooler than than the 312DegF max CHT I recorded with the 120MJ with 60/120J combo.
