VARIATOR WEIGHTS:
The engines have pretty good torque have descent power as long as you do not go overboard.
Check your Variator first and see if Both Pulleys are the Same Size.
If the Variator itself is smaller than the Outside Pulley you can get what they call a PERFORMANCE Variator that is the same size as the Outside Pulley.
Belts will only climb as high as the Smallest Pulley.
So by having Equal Size Pulleys the belt now can be made to climb higher for more TOP END SPEED.
Also weights play a major roll on making the Belt climb higher.
Heavier weights Require Less RPMs to push the Belt up the Variator.
Lighter weights Require Higher RPMS to push the Belt up the Variator.
Roller Weights - Will Change your RPMS by 500-600 for every gram up or down.
Slider Weights - Will Change your RPMS by 200-350 for every gram up or down.
What I did is experiment with different Gram Rollers first they are cheap.
When I found the weights that I liked and at the RPMS I liked I then put in Dr. Pulley Sliders and went ONE gram Heavier on the Sliders So my Rpms would be almost the same as with the Gram Rollers I liked. So I gained just a little more top end with the Sliders due to Fact they are 1 Gram heavier than the Rollers and still the same RPMS.
Heavier weights will push the Variator out and squeeze the Belt more so it climbs higher for more top end. BUT to heavy of weights will make your takeoff and Mid-range sluggish.
Also Heavier weights will cause your RPMS to drop so you also have to watch out for that.
You want to run at or Near the RPMS the engine makes its MAX Horsepower. If it revs much higher than that the engine is Not producing any more horsepower and in many causes will loose horsepower due to floating valves etc.
Lighter weights take MORE RPMS to throw out the weights to Push Variator out to push the belt up the Variator. To Light and it will not push the belt as high as possible and you will loose top end but you will have a quicker takeoff and Mid-Range because the belt is staying in the lower gearing of the Variator longer.
TALLER GEARS IN THE TRANNY:
Changing the gears behind the Clutch to taller gears for more top end speed:
If you Change the Small Shaft that the Clutch turns by 1 more Tooth AND the Big Gear that the Small Shaft Turns by 1 Less Tooth that Drives the Output Shaft that turns the Wheel or (Sprocket with a Chain) you will gain about 4-5 mph more. For every number of teeth changed you can expect about 4-5mph more Top End Speed.
Here is how to change the Gears:
