Stock Varriator weights

[dobbs2k]

What is the average weight of the stock varriator weights on a 50cc QMB engine?

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

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?

[felliott]

Sliders last longer than rollers.

[90GTVert]

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.

Hi
For fine tuning your cvt i recommend a roller tuning kit and experimenting until you find the proper weight

Once you find the proper weight for your needs then go with sliders, go one gram higher in weight for the sliders as opposed to the rollers

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.

[dobbs2k]

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

My old 4Tcame with 8 grams and I went to 5 grams and takeoff and uphill were better with same top end just turning more RPMs

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.
