Hi Theres no way of telling for sure without weighing them, between low quality control and individual choice of the manufacturer theres many possibilities. Heres a chart with the different rollers for different scoots www.beedspeed.com/html-pages/variator-roller-weights-chart.htmTake care and ride safely Yours Hank

6-8g seem to be the most common.

If I were to get a set of slider weights, would that be better than roller type weights?

Sliders last longer than rollers.

I usually get a little more performance from sliders, but the big advantage is that they last longer like felliott said. It takes a long time to wear out a set of sliders under normal circumstances.

So I swapped out my varriator weights on Saturday to 4.5 grams, my scooter now revs to 8000 rpm. My question: Is that a safe cruising rpm to be at or should I make the weights heaver?

Hi That is a very light weight for a 4t engine and the revs are a bit high, i cruise easily at 3,500 to 4,000 with a speed of 35 to 40 mph. I would once again recommend that you get and experiment with a roller tuning kit.

Have you tried any other weights? You may see more speed with a little heavier weights and a lower cruise RPM.

I purchased the tuning kit from enviromoto. So I should increase the weight? Well once this "hurricane" goes away I will continue tuning.

So I have found my best weight combo!! 5 grams. If I were to upgrade to sliders, I understand that I need to get them one gram heaver than the tested rollers. Is that right?

I changed out my weights today to 5 gm rollers. The OEM weights were 8.5 -8.6 gm. I was surprised after reading many posts about roller weights that they were this heavy, most comments were in the 6-8 gm range. So far huge difference in performance. I am a larger guy so I expected some improvement by lowering the gear ratio. I am moving right up hills that slowed me down significantly before. I wasn't able to do to much comparison today due to the weather but I did ride a little. I have a long climb that would bog the scooter down to 18 mph before, today I climbed at 25. On a shorter steeper grade I checked the ave speed between two markers from a dead stop. Before 14.3 mph, now 17.6 mph. Speed is checked on a GPS.
I have some 4 gm weights also and plan to check those and a combination of 4 & 5 to yield a 4.5 gm. But first I want a chance to check my top speed in this configuration.
