Hy guys! I was wondering if you can help me out in my decision. I have a completely stock 2015 mp3 500 sport abs asr and I want to put some salt and pepper on it. I want to start with the best choise for the variator. Dr. Pulley sounds to be good choise, I can use my stock variator but what weight, with sliders or not, with fizzy washer (what is that?! )) ? I need please exactly details because I don't know more about scooters. Another thing is that I don't want my 500 to go crazy with the fuel consumption. I use mostly in town so I need more a setup for town use. Beside variator, what mods can I get for a real upgrade? Thank you so much guys

hello and welcome to the forum
the fizzy washer sounds great lol. it lets the belt sit slightly lower on the variator so when you go to pull away the revs will be slightly higher in effect you should pull away slightly quicker. may be wrong of course but that's my understanding in a nut shell.
air box mod to let it breath better is easy to do.
rollers are a very subjective thing on any scooter forum. dr pulley gets most peoples vote I personally didn't find them that great and in fact went mental and put in much heavier weights 22 grams I think and really really enjoyed the lazy sound of the engine and it felt like a much more refined ride. if you want your engine to rev beyond that of a 50cc sounding engine id go with that J COSTA one. your engine will sound like its trying to get out of the frame and run ahead of you.lol. but again I found this system was just not for me as I am very old at 50 so need to think a lot more before I can react.
the thing I had most trouble with was getting the twin spark system running perfectly. I found one plug was always getting fouled up more than the other. stupid design anyway.but that's my opinion. I am sure the smart ones in here will chip in very soon.

I'm in the J COSTA camp. I've tried a few different systems on my Vespa and it performs the best. It's paired with a Malossi kit with the Forcemaster2 at the highest setting and a remus exhaust. I find the pull off the smoothest with the J COSTA in and at higher speeds it also seems to perform well.

I'm also a J Costa disciple. Stock set up is for urban. Roll-on will be especially good for getting on and off the collector lanes!

I would go with this as I believe the X9 500 has the same engine/wiring loop as your BV

Dobeck guys are very helpful. Plus it is much less costly

with the JC you get more a on/off experience with Dr P you will get a smooter ride with the same results for less money Tested them all

Maybe a hint of J Costa's circuit racing heritage. Perfect for urban point and squirt.

No need for any other stuff like white counter springs etc...

I'm using the Dr Pulley 19g on mine. I started with the 18g but I did not like to Rev to high. At 19g I get the same feeling than the stock rollers.

Where did you get your 21g Dr. Pulley? I'm eager to try that next. I'm about 5100 miles in 3 years and I'm going to change my belt soon. I wanted to try different weights too at the same time.

I wouldn't go any lighter than 21g because with these and the yellow springs I can activate the ASR if I accelerate hard from a stop and hit any bumps, and it didn't affect the top-end at all. If you go lighter I think you might lose some top speed.

2015 Mod.
Hello fellow Impies. My Matilda is now 6 years old and for the passed 2 years I have been driving with the JC with a 2.5 mm Fuzzy washer and she runs almost like when I bought her new. I am planning eventualy on putting a Dr Pulley Sport clutch in her when I finaly have the time. I have one Problem at the moment though. My Matilda tends to want to drink too much and I am getting very very bad Gas Mileage. I am supposed to be getting at least 250 Km. to the Tank of gas, at the moment I am getting only about 150 to the Tank. How can this be? Any suggestions would be very appriciated!

I would start a New Topic on this issue vs here which is about Rollers.

Measured results
This topic has been bounced around the forum for years. I would love to see some hard numbers on the improvements from roller and washer mods. I have to say my old 500 delivers 0 to 45 mph acceleration that normally walks away from cars at lights in city driving as it is. I would also assume increasing acceleration shortens belt life, which is already too short. Increasing the stress on the rear axle would likely also shorten the already fairly short life of the axle bearings. What the MP3 needs most is a much more durable aftermarket belt (Kevlar reinforced?).

Well got news for you the OEM belt is a kevlar one

Malossi and Polini belts are smaller there for need changing more often every 6000km

Wear it wont affect the wear of the belt or axle your only changing the time its accellerate not HP or Torque

iff you gonna chiptune like i did on my first mp3 with 48 bhp on the rearwheel and 71 Nm torque yes then you need to

I thought we had this debate a long time ago on a different thread.
Many of us posted pictures of the OEM Belt and the Malossi and found no difference in the width of the Belts.

We have . In the US, the recommended belt change interval is just 6000 miles.
As I said, some aftermarket supplier needs to come up with a much longer lasting belt - more kevlar, graphite fiber?

with my 2019 500hpe, I was thinking of changing mine at the 10000km service. Sounds like 21gr setup is the best for the 500's?

No it isn't. It has Aramid fibers, but not Kevlar. Of the three, only the Malossi belt has Kevlar.

Kevlar is just DuPont's brand name for their aramid fiber.

Yep !

Is aramid fiber the same as Kevlar?
Aramid Fibers, trade names Kevlar®, Twaron®, Nomex®, Technora® Aramid fibers are another group of super-heros of the fiber world. Kevlar and other polyamides, all conjure up images of ultra strong materials that are elbowing out more conventional construction materials such as steel.

I ordered some Dr Pulley sliders from Mx-performance (the 21g)... still waiting for them after 17 days.... I hope they are legit.

I have finally received my new 21 g sliders from another vendor.
Installed yesterday with a new belt. I like how it feels, it revs a little bit lower for the same speed. I did lose a little bit of power compared to the 19 g but I do appreciate that I stay around 5,000 rpm at 60 mph.

18 g: too light.
19 g: I really like how "punchy" the scooter is in the non ECO mode.
21 g: A more smooth ride. Less "punchy" than the 19 g.

Next time I'll try a mix of 19 and 21 g. I think that might be the sweet spot.

Now try some Malossi yellow clutch springs, you'll be impressed how much difference that makes from a dead stop.
