What is original roller weight? I changed 29g dr. Pulleys and checked weight of the old rollers and they were 33g!
-
I thought they were 30? Thats on a carbed model maybe? Maybe the fuel injected 2009 & up's are more heavy? :-*
-
My originals were 30g. If you order original rollers from a Kymco dealer you'll get 30g. I was not aware Dr. Pulley made 29g. Last time I looked they made 31g, 28g, and 26g. Maybe even some lighter for drag racing.

Is your xciting injection model?
-
I have 500 ri -11. The roller weight is 33 g. My old ones needed to be replaced so I bought new ones ( kymco original ). Also 33 g
-
Wow I did not know they made such a change? Your RMP's must be much less than the carbed models at HWY/FWY speeds! That is why I ordered 31G Dr Pulley's so my RPM's would be a little lowwer. The torque of the fuel injected models must be enough to handle the increased weight to give you the same take off speed? :-*
-
The fact is that they are a bit to heavy. It engages to early. I wouldn´t mind a set of 30 g.

The FI engine reaches both maximum torque and power at lower revs, so it's a bit hard to
compare like this.

Rollers don't work that way... They are to control the rpms not be influenced by them. The torque spring in the back is what controls the shifting point, or operation of the var. If you lighten the rollers to delay the feel of take off you will be reving thru the roof at or near top end. A stiffer spring, or shimming the spring maintains a lower gear for take off, and improves turn acceleration, as well as engine braking on let off. If your top end/cruise rpm's are good DON'T lighten the rollers. Shim the spring instead.

Scoot-n, is your bike a Euro model? That may explain the 33g rollers? If go down to 28g your HWY RPM's will go way up. The bike will go from 0-60 much faster, but 60 may be your top speed. Lowwer weight rollers faster take off speed, heavyer weights higher top speed (if engine has enough power that is), because the heavyer rollers will lowwer your RPM's. I would go down no more than 1 or 2g at most if you want more take off speed. Shimming the clutch spring is no easy task unless you have the tools like an impact wrench, 50mm socket, C clamps and such. I would leave that to a mechanic or for someone with the knowledge like Zombie. Take it from me, leave it stock. There have been many post here where people have tried to do this or that, and have done nothing more than screw up their bike. :-*

Dr Pulley weights can be found if you Google union materials in Taiwan. The guys name to talk to is Paul.

I bought mine here:
http://www.buggypartsnw.com/ (http://www.buggypartsnw.com/)
They shipped them half way around the world to me for $9.

Mine is a 2007 carburated USA model.

Thanx for link but cannot find rollers for xciting 500 size 28 x 22. :-\
-
Any ideas where i can find normal rollers?
-
A Kymco dealer? :-*
-
Stadium Yamaha online. Mention this forum and possibly get a discount.
KymcoParts 123 online is another.

The sliders I needed weren't listed either, I emailed them, they had them in stock.
Paid over paypal, shipped next day.

You will find the same issue with Most shops. You have to talk to someone. The adds cannot possibly cover everything they carry. They would have to update every day!
-
I don't have any "issues", since I do some freelance web desing stuff I'm aware of that so
I ALWAYS e-mail everyone. ;D
-
Whoa, Nelly... Good boy. :-*
-
I think that xciting 500 have 30g rollers and xciting 500i and newer have 33g, cause better torgue with lower rpm. Anyway i took dr pulleys away cause rpms gets too high when cruisin. They were 28g not 29g as i ordered. So send some email to dealer he will take these wrong sliders back and send me new 31g dr. pulley sliders :-) Hope these 31g sliders work ok.

I ordered Dr P's right from Union Materials. 31g. After about 2,500 miles they are wiped out. Almost down to the metal. I'm done, no more after market. And as for after market clutches, such as Dr P HIT clutch and such. You can buy about 8 stock Kymco's for the price they want for one. I have 30,000 miles now and my clutch is fine. It locks up good and must not slip as there is no glazing! And the bell looks perfect. So the HIT locks up faster and your 0 to 60 is a half second faster? Big deal. They should cost $50.00-60.00 max. I have also read on diff forums that after installing Dr P sliders, that soon after, their belt snaped? Are the Dr P's related to my belt problems? I can't say for sure? But I have used them 2 times, and both times my belts have gone at 1,500 & 1,000 miles. I'm done. :'(
-
How pulley weight can snap belt, i wonder! Mayby installation error? Too light or heavy weight? Kevlar belt?
-
As I stated, 31g, 1 oz more heavy than stock. Installed perfect by me, not mechanic. Followed their instuctions and watched video several times on how to install on an X500. Held variator together as I tightened nut. They could not have slipped out of place. They were in correct place when I took it apart. I did not say they caused this, just that everytime I used them my belt broke? :'(
-
It's strange, but absolutely no way that it can be due to the sliders since they don't
get anywhere near the belt. Lighter weights = more revs = more acceleration and that
can shorten it's life span, but nothing else.
But.. maybe you put something back together wrong.
The abnormal wear also suggests that.
-
My variator was ruined in far less than a year while sliders were in it. Now back to stock rollers and no hints of problems in 8 months. I never did have a belt break, though.
-
Hoolander is exactly right, and stated so better than I could or did. The first time I put Dr Pulleys in the boss froze inside the pulley half in about 1,500 miles. Cleaned everything up, put back together (at a shop), and in about another 2,000 miles broke belt, and inside pulley was egg shaped, the boss could just flop from side to side. I could not believe it lasted that long? I think it lasted that long because I went back to stock weights? I should have put in a new inner pulley half when the boss froze, but shop in Ill where it broke down did not tell me what had happened as they had not torn into it yet, and shop and I both thought it was just a broken belt. With my last (new variator) I put Dr P's back in thinking they were not the problem? 1,000 miles latter my new variator and belt are toast. The ramps on the inside of the variator looked as if they had been ground by metal to metal contact? Distroyed completely. Hoolander! If I were you I would replace your inner pulley half with a new one! It may be a ticking time bomb? And with belts at $221.00 now, (a complete rip off by Kymco), it may be the best preventive maintenance you could perform? The boss should be ok as it is steal. The part is only about $40.00, much cheaper than a belt and or a complete new variator. I agree with Cortez. I have no idea how the Dr P's could cause this problem, but it happens! I talked to one mechanic a couple of years ago when I was looking into DrP's, and he stated that he liked Dr P's in a Dr P variator, (because the variator was made for their sliders), but did not like Dr P's in a stock variator, (to many problems). I should have taken his advise. :-* :'(
-
Painfully expensive lessons. I wasted several set ups trying different "toys". Mine cost MUCH less tho. I bought my scoot for the price of your belt.
-
Yesterday i out 31g dr pulleys in they seems to work ok. Hope my belt will last. ;D
-
Fingers crossed...
-
Fingers crossed...
Thanx. Here in finland we do thumbs up ;)
-
Still working ok. Anyway ordered original 33g weight and will replace them.
-
Did your RPM's go up with the 2 gram less weight rollers? :-*
-
Yes a little. I think about 500-700 rpm. I think acceleration was only little better, but fuel consumption went up.
-
Very nice to drive with stock weights. Acceleration is slower but over all sound is better. Had some problem with the first washer, next crank case?
-
First washer, next crank case? Make sure beveled side is against crank case or it's good bye belt. :'( :-*
-
next crank case? What it means is the washer goes on First next to the crank case. Like Sissy said be sure the bevel side in facing the case. It acts to "true" the surface for the ramp plate.
-
Sorry my bad english, I meant first washer, next to the crank case.
-
It's all good. We understood...
-
Finlands sak är vår... Hello neighbour. How good are Dr. Pulley? Big in USA but in Europe? Reliable? Quality?
-

Hejsan! Hello neighbour, I took them away, only reason was little too high rpm. I think rpm rose up about 500 - 1000 rpm. Fuel consumption up 0,5l/100km. They worked very well and acceleration were much better than with original weights. I can sell them to you if you want to try? I have 31g and 28g.
-
Hi
Was it too high rpm even with 31g? How many km on them? Price? Please send me pm.
