Ok guys. Im really sick of the misinformation going around on this forum.
There are 3 types of derbi moped motors made.
Piston port engines
direction of rotation: counter clockwise facing magneto
Pyramid reed engines
Pyramid 3-reed valve, Crankcase mounted
direction of rotation: counter clockwise facing magneto.
Flat reed engines
Crankcase 2-reed valve induction with triple transfer port distribution
direction of rotation: clockwise facing magneto.
Max engine RPM: 6500
before some of you get all uppity, I copied that out of the repair manuals for all 3 motors except the pyramid reed which is off an old promotional ad I have.
