Agility 50 very slow going up hill

Hi

I think that the heavy rollers are not doing all the work
because if you put only these one you cant have the sam result than me

the rollers are mixed one to one and all is balanced

I think that lighter rollers are starting the job and heavy rollers work together the lighter to finish the job

But i will investigate to see if i made a mistake or not

I understand your point but trust me on this one. It will fail!
Imagine dropping a marble, and a feather. Same effect/result

Hi

OK i will made a big research on this

So if the lighter only float and do nothing i can remove them ? They are a weight and this weight has no effect never ?

And why honda use this sytem of different weight in the honda reflex ?

Nice day

They use different ramp lengths, and their var is proprietary. No other scooter var will fit them.
Yes you can remove the lighter weights. Several people here have done this.

They all post within a week that either the var exploded or their new weights were worn to the cores.
The guys that designed these vars went to Var school/scooter school/ or at least hit 11th grade, and learned how to do it. We just attempt to make them better.

Just kidding. I know they went to that bigger school that comes after 12th grade. Forgot what it's called tho.

Hi

Thanks to all i am learning each day and i hope the members too.

You are right for honda the ramps are not the same

For the moment the only disavantage i have seen by mixing balancing weight is that the lighters rollers wore more because they move more often

But i am sure that the result is not the same by putting 6x7.5g than 3x8.5g + 3x6.5g

I am not too experemented to know why but its a fact the variator dont work the same

To be continued

It's because your lighter rollers are barely affecting the var. It's sort of like they are only able to use a few grams of their weight.
For rollers most people here found 6 x 5.5 to be the magic number. (with a 1500-2000 contra spring)
7 or 8  gram Dr. Pulley sliders equal the same rpm depending on rider weight.

My guess is the total of 33 grams (6.5 x 6) is equal to your 8.5x3=25.5 plus the rest of your rollers. At 7.5 each you are actually only applying 7.5 total. 7.5 + 25.5 = 33. That equals the 33 most of us use. That means you have 15 grams floating.

We all had to learn this crap too. Some of us the hard way.

Hi
Thanks for the calculation

For me its
3x8.5 = 25.5 + 3x6.5 = 19.5 so the total is 45 (with equal rollers that is 6x7.5)

With you calculation
3x8.5 = 25.5 + 1x6.5 = 6.5 so the total is 32
45 - 32 = 13 g floating (two of the three lighter in fact)
Is it right ?

Where i can see how to make them its very very insteresting ?

What I was attempting to point out is your set is most likely acting around 33 grams. That is the best running weight for most of these engines.
The idea is they will average out.

You can use a gram scale to weigh your rollers, and either remove metal or add epoxy inside to adjust your weights to save a few dollars, and fine tune what you have.
Lots of us have done this. You can also punch out the metal cores, and insert them into new rollers if the shells get worn.
