3rd Run changed Variator & Sliders-5 gram(stock weight) (plus previous, K&N Filter & new CDI)
Flat ground max top speed = 38-39 MPH. Max RPM's = 8500-8600
Hill climb (very steep) = 2 minutes 21 seconds
Down hill max top speed = 45+ MPH. Max RPM's = 10000+

4th Run changed Sliders-4 gram (plus previous, K&N Filter & new CDI & new Variator)
Verified stock main jet before run. It is a #85
Flat ground max top speed = 36-37 MPH. Max RPM's = 8400-8500
Hill climb (very steep) = 2 minutes 20 seconds

5th Run changed Sliders-mix 4 & 5 gram (plus previous, K&N Filter & new CDI & new Variator)
Flat ground max top speed = 37-38 MPH. Max RPM's = 8800-8900
Hill climb (very steep) = 2 minutes 12 seconds
Down hill max top speed = 45+ MPH. Max RPM's = about 9,500 rpm's

Summary
Final run (5th) seemed to be the best of top speed plus hill climb speed. This was with three 4 gram sliders & three 5 gram sliders, or 3 grams lighter overall versus stock (6x5gm=30gm) which is a 10% decrease in slider weight.

This increased stock flat/level top speed from 32/32mph stock to 37/38mph, or a 5 mph increase which is 15%.

The timed hill climb went from 2 minutes 25 seconds on run number two to 2 minutes 12 seconds, or a 13 second decrease which is 9%.
