NARAKU COMPLETE 139QMB AND KYMCO RACE VARIATOR KIT. The Naraku HS-High Speed vario is an evolution of one of the most
successful variators for 4-stroke vehicles. The roller ramp design results in a maximum of torque and top speed. The
key to a good variator is its ability to keep the engine at constantly high rpm over a wide range of vehicle speeds,
which makes the HS variator one of the best ones for 4-stroke engines. Even other renowned manufacturers find this a
hard nut to crack. Another advantage for tuners without much experience is the fact that the Naraku HS variators come
already pre-adjusted.
This version comes ready to install for all standard 50cc engines without modifications. Using a
stronger torque spring is not recommendable for 50cc engines without further tuning. However, if other tuning parts are
used, a new setup may be required. Included in the delivery are the complete variator, open variator bushing with speed
control washer as well as a set of variator rollers (16 x 13mm) suitable for 50cc original cylinders.
Note: Please make
sure this scooter engine part fits your particular scooter model. Many scooters have the same name but use different
engine parts depending on the year of manufacture. SKU NK900.21 Old SKU NK600.07 RP-NK900.21 variator – vario kit Naraku
