Your back wheel is spinning awfully fast for a warm up. I remember people have fixed it in the past by turning the idle a notch down since it was too high. I had the same issue myself and turning the idle down did help. It runs at a lower idle, but still very smooth and the back wheel doesnt spin at all.

it seems to be fast but its allways has been like that so never messed with it . I just let it finnish its warm up or use the back break before i come down of the centerstand. Im going to do a test drive now

Yeah, mine has ALWAYS spun that fast. It warms up faster in the summer, but the wheel still spins. That's totally normal for some bikes.

omg what a difference up steep hills at 50 wow id say a 5mph boost

jfrost2 · Post by **jfrost2** » Wed Oct 07, 2009 7:50 pm

You're able to hit and maintain higher RPM's because of the unique slider shape reaching further up the ramps.

You'll get even more power out of the sliders if you upgrade the variator itself to a Dr Pulley brand. It's shaped even better and specifically for the sliders.

I am about to do my 6000 mile service (closer to 6500 mile now

) so I will be changing my rollers. I've been thinking this may be a good time to switch to sliders....

Kneil67, are the sliders the only mod you have done or are there other factors that are contributing to your scooters improved performance? Other than the additional 5mph at the top end, are there any other performance improvements/losses? Do you have the same acceleration from a standing start?

This seems like it might be a dead simple mod to make since my scooter is going to be apart for service anyways...

Thanks!

jfrost2 · Post by **jfrost2** » Wed Oct 07, 2009 10:57 pm

Nothing you can really lose if you use a 11G set of sliders. The standard rollers are 11.25G so the weight is nearly the same. Only gain because of the shape of the slider's design.

Man... I've just been reading about the Performance Package with the Dr. Pulley variator, sliders, and clutch spring... I'm getting the freakin' VooDoo bug... totally want to do the mod...

Kaos, your VooDoo site is awesome. Very helpful. Learned a bunch there...

Thanks Skootz! I'll be adding more to it soon, honest. My wife totaled her car on Tuesday(everyone involved is ok!) so paperwork has been the word of the week. Look out for some more Voodoo soon though!

Should the belt be changed at the same time when you replace the sliders? Is it easy to figure out how to place the sliders in the variator? This will be my first attempt at taking the variator apart. I just bought one of the emergency impact wrenches from Harbor Freight for 20 bucks. Anything else I need to be aware of as I take the variator apart?

just pay attention to how you pull it apart to put it back together modern buddy tech section is the bomb. check out my full break down srry no tech talk not well versed. but it gives you a veiw of not knowing.

Belt needs to be changed ONLY when changing the actual variator itself to any other brand besides what's stock. It's because the old belt is worn to the shape and angle of the ramps on the stock variator, it needs a new belt to form to the shape of the new ramps for max performance.

You own stock in nylon or something?

A belt that's within spec will wear into the new shape (1-2 degree difference from stock or you've got the wrong part installed) just as well as a new belt. Plus it'll keep an expensive mod from becoming a ridiculously expensive mod.

Change the belt when it's worn down to below it's service specs (19mm width).

I'll say this about the Dr Pulley variator: It's an incredible upgrade for a low quality variator ($999 SC00T3R), but I'm still not convinced that the PGO stuff needs replacing. Sure it's better, but you could be 3/4 the way to better forks for the same money.

I never changed the belt when I replaced my variator and didn't notice any difference.

I may have worded that wrongly, what I meant was by not changing the belt there was no difference to acceleration i.e. I don't think a new belt is necessary when changing the variator, but the sliders made a difference.

Have about 250 miles on a new Dr. Pulley variator, 11g DP sliders and a new Gates kevlar belt. I thought there would be a noticeable difference in speed but didn't guess it would be slower. I'm 5 mph slower going up the hill (12% grade) to my house (45 bmph now) and about 5 mph slower at top speed (around 70 bmph now).

Should I try different weight sliders? Will there be a tradeoff between low-end torque (for going up hills) and top speed? Do I need to have more miles on the new variator, sliders and belt before I notice a difference? I'd appreciate any suggestions?

I'm doing the Dr. Pully variator mod too (with the 1500rpm main spring), and Kaos recommended 12g sliders to me...

I guessed as much, but didn't think I would lose both low and top end with the upgraded parts.

My stock belt and variator are still in good shape but the rollers were starting to get flat spots. I think I'm going to switch back after a 1,000 miles or so just to see if I'm imagining things.

Post by **Lostmycage** » Tue Oct 20, 2009 4:42 am

You changed too much at once and introduced too many variables.

Put the stock variator and belt in with the 11g sliders and see how that feels. Then make one change at a time and see if you can find where the ball drops. If you want a true feel for what each part does, install them all individually and leave all other parts stock (ie. stock Var & Belt + sliders; Stock rollers & belt w/ Dr P variator; and Stock rollers & variator w/ kevlar belt).

I'm assuming you haven't changed the springs? Those will affect the top end and acceleration just as much; both positively and negatively.

If he's not running 1500RPM clutch/contra springs, then 12g is going to be too heavy. 11g's is good for a stock/semi stock bike.

See? What do I know...

So Kaos, if I am using the 12g sliders and the 1500rpm contra spring that comes with the DP Variator performance kit, will the stock clutch springs still be OK? Or should those get upped to 1500 too?

I'd recommend going with 1500RPM clutch springs as well, but you don't HAVE to. They give you a much better off the line snap with no top end penalties. Don't do the 2000's though, as they don't have enough holding power to keep the clutch from slipping.

I agree about the variables - I will have to apply the scientific method! If I had to guess at a thesis, I would say the sliders would have the biggest impact. Maybe I'll start with reinstalling the stock variator and belt while using the DP sliders. It looks like I'll be heading to Harbor Freight to buy a dc impact wrench.

11g sliders on my stock buddy feel great. Obviously not a large speed gain, but acceleration is very quick and smooth. Highly recommended.

Hello BuddyLand:

Does anyone know if Dr. Pulley sliders by the way they are shaped, actually pushes the variator out more than regular cyclindrical shaped roller weights of the same weight, when engine is at top RPMs? If yes, are you getting more top speed?

Hello BuddyLand;

You all got to check out these 2 websites...........
-----------------------------------------------------------.

I found the website of the company that makes Dr Pulley products.

http://www.unionmaterial.com/

On this website, there is a video diagram comparing how Dr Pulley sliders and regular round roller weight function in a variator. It does a Chinese song in the background to entertain you, kind of like a school fight song at a football game.
It is kind of amusing........

I found this website about the company Union Material LTD of Taiwan.
