Mixing Sliders? By jomama0867 (Read 512 times)

I recently narrowed my variator weights down to a range of sizes. As it happens, I was convinced that 13g was the winner, but found that they in fact were just a bit TOO heavy. I already owned a set of 10g sliders (same manufacturer), but they were ENTIRELY too light!. Is there any problem in alternating 10g and 13g sliders (creating . . . 11.5g?!?)?

as far as i know, lots of folks mix weights and it's considered perfectly acceptable.

Rollers are ok to mix with a 1g variance, sliders could have issues with tipping over.

I think Jerry is right stay with rollers of different weights but don't mix with sliders or stick all sliders of different weights let everyone know what happen either way.

+10 on mixing sliders also you will hear a lot of weight rattling. To much weight variance from high to low is not good and not practical. Having only 3 heavy weights will require higher rpms to move the variator out the same distance when all 6 are used. So what are you really gaining nothing really and actually loosing performance. Buy the proper weights and be done with it.

A lot of people mix sliders and rollers on the big scooters. (burgmans and majestys) (with great success too) As long as the same size weights are directly across from each other it is fine on the big scooters and I don't know any reason you can't at least try it on a smaller one.

Both lighter weights and heavier ones are getting the same centrifugal force on them its just the heavy ones push harder is all.

Yes both gram weights get the same centrifugal force BUT because of the difference in the weight they move up the VARIATOR RAMP at different times. That is why LIGHTER WEIGHTS require HIGHER RPMS to get to lets say 40mph WHILE HEAVIER WEIGHTS require LESS RPMS to get to 40MPH.

So as you can see the lighter weights will be lower in the ramps while the heavier weights will be higher and actually pushing on the variator. Due to the lighter weights now trailing the heavier weights being lower in the ramp there is now some slack between the Variator and the lighter weights and you will hear more rattling.

Very simple to prove it to yourself. Put in 3 say 12 gram weights and run it up to say 30mph and see what the RPMS are.
Now put in 3 11 gram weights and run it up to the same rpms you ran it with the 12s and see what your mph are now. Or run it up to 30mph and see what your rpms are at compared to the rpms with the 12s.

Thanks to all for the feedback. I had a spare OEM variator so I tried the combination anyway (didn't really want to use my 115mm), three 10g and three 13g, and ran about 25 miles. On inspection, I didn't notice any adverse damage to sliders or variator. There seemed to be a slight improvement in performance, but nothing significant. I'll probably buy the correct weight sliders, but it was interesting trying out the theory!

On the forums dealing with majesty and burgman what they recommend is so many grams of total weight for your style of riding and how they arrive at the weight is of little importance. Just as long as like weights are directly across from each other. Once you find the total weight that is right then its time to get them all the same if you can.
