Anything you do will be an improvement, as long as you go lighter........
you only need 6, whether you're using regular old rollers, DR Pulley sliders or ADIGE creepers (they're hexagons).
They all work. Each have advantages and disadvantages.
Rollers are cheapest @ $20-40 a set .....Adige and DR Pulley sets go for $50-70 a set.
The weights you choose depend on many things, including your weight and where and how you ride.....
the heavier you are, the lighter the weights you want to use.
the faster you want to accelerate from a stop, the lighter the weights you want to use.
the steeper the hills you need to climb, the lighter the weights you want to use.
the faster you want to cruise at topend on the highway, the heavier the weights you want to use.
the higher the gas mileage you want, the heavier the weights you want to use.
It's pretty logical when you think about it.....
you're just setting the CVT up/down shift point by varying the weight.
you now have 6 -26 gram weights.....
you probably want something between 17 gram and 21 grams, unless you're over 250 pounds, then you want something between 15 and 17 grams each.
There's no perfect weight combo that works for every rider....everything is a trade-off.
A little experimentation is good for the psyche!
If you're still totally stumped on how to proceed, just do what Sawman would tell you and buy 6 19g DR Pulley sliders.
Thanks BRed..I understand everything...I am 230 so I will try the 18 grams.....I am still thinking anout the Costa...but I think I will do the weight this first...oh I emailed you about the windshield this morning.
