I am looking for increased take off power and potential speed enhancements for my 2009 Kymco Xciting 250Ri. I was thinking of starting with the Variator pulley weights. Does anyone  know what the weight of the stock rollers in the variator are? What are the best upgrade weight for performance? Weight brand- Dr. Pulley some other brand?
What are the other mechanical upgrades that people have perform on the Kymco Xciting 2520ri? Are any worth the performance enhancement?

Thanks

According to the online parts catalogs, the Xciting has the same OEM rollers as my People 250 and I am using the SR2318 in the 21g weight and I love then.

This was my last invoice for then:

I could be wrong, but I think Matt no longer carries the Dr. Pulley (Union Material) products.

Regardless what he carries he is an expert... and so worth bending his ear if upgrading is a consideration.

He helped me immensely when I upgraded up Bet & Win!

Paul @ Union Material personally recommended NW Buggy and you can send Paul an email directly and order them from Taiwain if you would prefer. When I ordered from NW, I had them in two days.

Thanks everyone!

Questions for TechGuy: When you changed out the weights did you increase the weight or just replaced with a better quality product. Also what did you see as far as performance?

I simply looked up the weight online at Union Materials site.  This was the weight they called for. It smoothed out the "lull" in the middle of the power band and I feel the top speed is easier to get to.  It doesn't run up to the top speed but it gets there with more confidence. I am a big guy.

I did buy used weights the first time, they showed some wear and I found i installed them incorrectly the first time myself and caused more "incorrect wear". I replaced them with new ones when my belt failed and I had to get into the CVT anyway.

This is the illustration I made after my "learning opportunities" the correct way to install them is not intuitive. They are designed to replace the OEM rollers in a scooter with an OEM variator, clutch, and belt



There are some out there that hate the sliders. I feel many of them have had a bad experience them because they install them incorrectly, they buy the wrong weight and go away from UM's recommendations, or they have changed something else in the the scoot. That means the slider weights need to be changed to accommodate  a iddferent clutch or variaotr ramp or belt or clutch springs or ...and no one really know what the shade tree machanci has done and the "mechanic" doesn't share all the changes he has done to his scoot before he orders the "stock OEM replacement" sliders and gets angry when the vendor says "Well you didn't tell me you were running a Costa variator with a Malossi race clutch with two yellow and one green spring and a Dayco belt."

On the new version of the DPS weights, there is a groove on the surface that is supposed to be the "top".  That should help in placement.

Another thing that may help, is to lightly debur or smooth out the edge of the ramp where the DPS weights will travel.  Your drawing shows them at the engine off position, As the rpms increase, the DPS weight will slide to the outside and lift the ramp up.  That outside edge of the ramp that contacts the DPS weight sometimes is so rough and sharp that it simply shaves off the weight surface.  I've done this to mine and after 11,000 miles of use, they still show little wear.

If you install the DPS weights "wrong", you can sometimes get some fun results.     I installed mine wrong once, with the top surface pointing to the outward edge of the variator.  The effect on my Burgman 400 was like adding another 100ccs.  I was shocked when I went to merge on the freeway.  RPMs jumped to about 7000 immediately with no lag at all and the bike shot forward, then without touching the throttle, the bike "shifted".  The RPMs dropped to about 6500 and the acceleration started rapidly climbing again.  I had the biggest grin on my face!  When I backed off the throttle, the RPMs dropped to about 5500 at 70 mph.  The only drawbacks to installing them "wrong" was (1) the RPMs would jump whenever any load was encountered (smoothly though), and (2) my riding behavior became more aggressive with the additional acceleration.  :D

When I installed them wrong.. twice. It feels like the belt is rubbing the CVT case and it won't exceed 60 MPH not matter what you do and it gets "buzzy" or "whizzy" sounding and bogs.  It does shift very quickly though. It did damage the sliders but not in a way that prevented them from working when installed correctly. 

They also slightly damaged my variator body.  If you look at the sliders, they have one side where the brass core can be seen and one side where the nylon coves the core.  I installed them so that the force of the CVT pressed the brass core to the ramp side wall, as opposed to having the nylon-covered end slide against the ramp side wall.

If they felt they needed to add a groove to the sliders to indicate the "top", it must mean that many people have installed them incorrectly and that they needed better way to tell the people the "top" of the oddly shaped sliders
