I installed a set of my Naraku Gear sets for a customer and took pictures to show how its done. We were both very satisfied with the results.
List of upgrades:
Stage 4 Powerpack
NCY Performance Cam
Leo Vince Exhaust
Naraku 72cc Variator Kit
7GDr Pulley Sliders
1500 Pill Springs
High Performance Coil
High Performance CDI
95 Main Jet
Malossi Kevlar Belt
Naraku Gear Set
Before the gear set upgrade this scooter would accelerate very hard and top out around 52 mph gps (still breaking in). After the upgrade acceleration was close to the same but the top end gained about 10% = 5 mph. GPS is now reading 57 mph on a long stretch 50 mph all day long with more power on tap. I wouldnt recommend this upgrade for a stock engine but it is a must have for the 72cc and above engines.
Here is how its done.
Remove CVT components.
Drain gear oil
Remove rear tire
Remove rear brake cable
Remove the 6 bolts holding the gear box to the case. Take note that there is one long bolt in this batch. Make sure it goes back in the right location.
Make sure your drain pan is handy to catch the remaining oil
Stock gears are a 52/15 gear set about 95% of the time
Naraku gears are 52/14 giving you about 10% more top speed without sacrificing acceleration.
The bearings
Naraku Gears
The large drive gear just slides off, easy as pie
The combo gear just slides out of the bearing, easy peachy
Old gears out
Make sure you use this nylon spacer on the new gear
Clean all the old gasket off of the gear box
Install gears the same way they came off, super easy
Add a little gasket maker to the case and install the gasket
Slide the two halves back together, take care to make sure the gears line up with the bearings
Use a little dab of blue locktight on the case bolts
Hand tighten to about 15 ft lbs and fill the gearbox, check for leaks.
Reinstall the tire and CVT components, nows a good time to check your rollers and belt for wear.
Done and done. How easy was that!
