Dr.Pulley HiT Clutch fit Kymco Xciting 500 HIGH PERFORMANCE CVT modification Dr

Description

Dr.Pulley high performance clutch HiT 282201
, new model V2 from 2012
In the Dr.Pulley HiT clutch two sets of springs are working: The clutch spring, inside, controls through the centrifugal power the movement of the clutch pads towards the clutch bell (for example at 3000 rpm).
The second set of "torque" springs, externally mounted, controls then the pressure by using a "push pin" on the clutch linings (in the example already at 3400 rpm) against the bell, thus preventing most of the slipping phase of the clutch.
Because of less friction, much less heat is generated. heat is lost power.
The scooter accelerates much faster because the full power transmission to the rear tyre
already exists
at 3,400 rpm, instead of 4000rpm with a normal clutch.
The HiT clutch is
very effective while driving with frequent speed changings: To accelerate out of curves or at mountain trips.
Or for a powerful overtaking.
The
graphs
show a marked increase in speed and performance especially in low and medium speed ranges.
With the two fully enclosed
sets of
spring , the clutch can be customized to all personal needs.
For example, if you want to get more power at start, choose a stronger clutch spring to increase the starting rpm.
If you want to shorten the slipping phase of the clutch, you should select a weaker pillow (torque) spring.
Extreme: To get an extreme start (wheely), choose a strong clutch spring, and a very weak (or no) pillow (torque) spring.
For those who do not want to experiment long, an average spring combination
is already installed

.
Importatant: Together with the HiT high performance clutch the use of not too light vario weights is strongly recommended. The best result you get with Dr.Pulley slider rolls with the same

The grip force comes not only from the centrifugal force and the friction
coefficient of clutch weight, but most importantly from the compression
mechanism—push pin & pillow system of HiT Clutch.
Better engine response, stronger grip force.
No more deformed and blued clutch bell.Improving the acceleration performance and engine response when re-acceleration. Better steel quality
Step 1: The clutch weight is driven to rotate but the initial rev is not high enough, so the clutch weight and the bell are in non-contacting
state (Fig.2.)
Step 2: When the rotating speed of HiT Clutch is high enough, the clutch weight will centrifugally fly outward to touch the clutch
bell to proceed the initial slippery clutch-in. The clutch weight is slippily contacting with the bell but the push pin is unactuated yet (Fig.3).
The friction resistance is produced between the clutch wear pad and the inner surface of clutch bell during the stage of slippery clutch-in.
Step 3: When the friction resistance is higher than the predetermined distortion strength of pillow spring, the pillow spring will be deformed or extended, and the push pin will thrust into the pillow to compress the clutch weight to grab the clutch outer very tightly. (Fig.4, the push pin is actuated and pressed against the pillow)
