DR. PULLEY 18X14 SLIDING ROLLER WEIGHTS FOR
125/150cc 4-STROKE GY6 ENGINES.
TRADITIONALLY, GEAR RATIO IS CHANGED BY THE UP-AND-DOWN
ROLLING MOVEMENT OF THE ROLLER WEIGHTS IN THE RAMP OF THE
MOVEABLE DRIVE PULLEY (MDF).
NOW THE INNOVATIVE DR. PULLEY SLIDING ROLLER WEIGHTS SLIDE
UP-AND-DOWN THE RAMP TO CHANGE THE GEAR RATIO.
THIS UNIQUE SLIDING MOVEMENT (NOT ROLLING) PROVIDES EXCLUSIVE
ADVANTAGES TO INCREASE CVT PERFORMANCE. WITH DR. PULLEY,
NO ABNORMAL WEAR WILL OCCUR EVEN WHEN RUNNING IN HIGH GEAR.
WE RECOMMEND STARTING PERFORMANCE UPGRADES BY
CHANGING THE VARIATOR ROLLER WEIGHTS FIRST.
HEAVIER ROLLER WEIGHTS= A SLOWER TAKE OFF SPEED WITH
MORE ACCELERATION AND A HIGHER TOP SPEED.
LIGHTER ROLLER WEIGHTS = A FASTER TAKE OFF SPEED WITH
LESS ACCELERATION AND LOWER TOP SPEED
