Modern Vespa

I would go look, but my 500 is in the shop ( a week now) so I am no help.( Its a hydraulic leak-the shop seems clueless).
But it ran just a bit faster, nothing jaw dropping, and the RPMs
never seemed anything to be concerned about.
Perhaps installer error.

Hello fellow mp3 peeps I've Been watching this topic with great intrest and was wondering if any one knows what sort of kit would fit the mp3 400 for example weight size how many and has any one fitted a kit to an mp3 400 yet and noticed any difference thanks for your time and knowledge

J Costa Nik.

Cheers jim sorry to be a pain do you know size i need and who sells them for the mp3 400 or any good web sites or uk dealers I'm just around the corner from CBS in whitton so might see if they can Fix them up

Dr Pulley sliders can be bought from http://www.scootertrap.com (the 15g ones for the X9 500 will be fine).
J Costa variators from http://www.sabreracingproducts.co.uk/

Cheers jim

Sorry to be a pain do I need the pulleys and variatir or just one or another if it's just one which do recomend sorry to be dim your help is indespensiable

The Dr Pulley sliders just go in place of your current rollers - you keep the Piaggio variator. The J Costa variator is a complete variator replacement. The Dr Pulley sliders apparently do 70% of the job compared to the effect the J Costa has, but they are much cheaper, say GBP60 including shipping as opposed to GBP205 for the J Costa.

cheers thanks again 8)

Redfone,

These are my estimated revs.

100km/hr 6400rpm
80km/hr 5500rpm
60km/hr 5000rpm

When i spoke to the service guys they don't believe they did anything wrong but they will have a look for me. I'll keep you posted on my results.

JimC, yes a Jcosta variator would be great but the Aussie dollar is so crapola atm it's a costly upgrade.

Understood! It was only a curmudgeonly moment late at night that led me to actually get one.

Kev

The instructions for the fitment of the weights is in the bottom of the container they come in. If you don't have it anymore just let me know and I will scan one and email it to you.

I finally took my bike in to the service centre. After basically being told i was an idiot by the manager, he agreed he'd have a look. He believed it was supposed to rev high and was not happy with me even suggesting the weights have been put in wrong. The W#@^%*&^

anyway, my result is it's fixed. They had put most of them in correctly, two weights had turned.

another happy ending

ello peeps sorry to be silly here but are dr pulley sliders the same as malossi rollers as im looking at fitting them to my mp3 400 if they are the same can some explain what i need to tell the shop

how many rollers needed

what weight are the rollers each

are rollers and pulleys the same thing

i just want the smooth constant accelaration that every one has commented on to be made true for my scoot tooooo

would be greatful for any assitance as not very clued up on what to tell the dealer to do they are a malossi main dealer for london and have been looking after my little baby very well jimc will know them well cbs in whitton

Nik, CBS will know what you need and be able to order it for you. Dr Pulley sliders are NOT the same as rollers - they don't roll, but slide. They can be used in a stock variator, and will last far longer than the Malossi rollers.

Cheers jim

Dr.Pulley have Sliders & HiT clutches for most CVT vehicles from 50cc to 800cc ( SR2519 for Gilera GP800 ) and its weight can be custom-made.
Anyone or
Hi, Redfone would you run a group purchasing for the members of this Forum?

I would be interested in getting a set for my MP3-400 If anyone else is interested let me know. Maybe we can get a group purchase together. I believe the size is 25x17 and 19gm. (is 2gm lighter than stock).

nik2003black, if your interested I'd be willing to get them and sent a set to you, much like redfone did (redfone doesn't have any more left).

By cheers for keeping me in the link I'm now leaning more the the j costa side I know they are a bit more but jimc seems to be given them a good review and customer service sounds good too il keep you updated on what I'm doing thanks again

Hi,if the members of this forum are interested in SR2517 & HiT251701 for Piaggio group's 400-500cc scooter such as MP3-400, Fuoco500, the promotion price ( only this time ) will be 50% of the market price.

I'm definetly interested in getting one set of 8, SR2517 19gm. sliders.
You can PM me on how to pay for them.

Dr.Pulley...you have PM! B

what would be recommended for the 250?
would they help with slow speeds being more smoother and easy to throttle?
cheers

If you talk about the HiT clutch, actually we installed HiT201203 in MP3 250 and the performance is amazing at low speed & re-acceleration.
i'll post the photo of MP3-250 with the HiT later.[/img]

Dr. Pulley,
Check PM, another buyer. That J.Costa may just have to wait.

How does the HiT clutch change the performance of the scoot in seat of your pants terms. I found a lot of technical info, but how does it change acceleration, top speed, etc. How does changing the clutch compare to changing the variator?

Cheers,
Jill

Jill, the clutch performs a different function than the variator.
The clutch engages the engine to the rear wheel at a certain engine RPM.
The variator changes the speed of the rear wheel in relation to the engine speed.

The HiT clutch doesn't slip as much as a stock one, doesnt heat up as much either and therefore should last longer. Paul (dr pulley) can explain it better.

I have been holding back from posting anything but my spidey-sense has been kicking in pretty hard lately. You may want to verify that the "Dr Pulley" person who is asking for a group buy, is actually a rep from Dr Pulley (Union Material) in Taiwan. They have not been responding to my PM's and I can tell you as a dealer that they do not sell directly to dealers due to a contract they have with MRP. This makes me think shinanigans are afoot. Just be careful before you start forwarding your hard earned money to some unknown.

Since redfone has purchased from Union maybe he can confirm if Dr.Pulley is a rep of Union Materials.

Although I have been in contact with Union via e-mail directly from the Union Materials website.

I guess we need to know who the Dr.Pulley really is.

If Dr.Pulley PM's me with his name, I can confirm that he is the same person I am in contact with at Union.

Hi,

Actually we don't sell the parts to the public but for promotion (such as less than 20 sets ) we'll do this .

Would the 19grams work for the 250?

That is a different engine-transmission altogether than the 400 & 500cc engine, so I don't think the 25x17 is used in that trans.

Dr. Pulley,
Since other people here doubt that you are a Union rep, please PM me with your name - the same name from the e-mails I got from Union.

If you click on my name (to the left above my avatar pic it will open my profile with "PM me" PM=private message

Or post your name on this forum.

Hi,

All of you can contact me via unionltd@unionmaterial.com, you can see this e-mail address from our webite www.unionmaterial.com
This is just a promotion for the members of this Forum to get aother option to try a different products at a lowest price.

In conventional racing clutch, people will use hard clutch springs to increase the engaged rpm high enough to have stronger centrifugal force to grasp the clutch bell or use heavier clutch weight to get strong grasp force.So conventional clutch might be divided as standard clutch or racing clutch.

But for HiT clutch ,we never call the HiT clutch as a Racing clutch.

Actually the main feature of HiT is to provide a solid engagement in whole speed spectrum ( ie, take-off from standstill , medium speed, top speed or re-acceleration at roundabout, overtaking and hillclimbing ) and its engaged rpm can be adjusted to be almost same as or higher that in the stock clutch if you want.
Through the website http://www.unionmaterial.com/Instruction%20for%20HIT-V1-mini.pdf , you can see the mechanism of HiT clutch and will understand its main function.
Due to excellent engagement, the transmission efficiency of HiT clutch is much much better than the stock clutch, no matter the vehicle is with stock cylinder or with cylinder bored for racing, you can feel the difference from the throttle response.

You can say HiT clutch is just a high transmission efficiency clutch to make less slippage,less heat buil-up to have better throttle response and more durable.

Thanks.

The email is not the same, here's the one from the website unionltd@ms14.hinet.net
and here is the one you gave us
unionltd@unionmaterial.com

Why don't you just give your name as requested and it can be confirmed you are with Dr. Pulley.

I smell fish here.

I just sent an email to UNION MATERIAL CO., LTD. requesting confirmation that the email & the deal Dr. Pulley provided is legit. Used the contact email from their website.

Dr.Pulley

What is the opinion here about the HiT clutches? I have decided to go with the J. Costa on the 400. Should I throw in the HiT clutch while I am at it?


I have no clue who Dr. Pulley is but he does accept Paypal. Paypal is pretty good about protecting the buyer. Often sellers will not even take paypal since it is so easy for the buyer to get their money back. I will often pay with paypal using my credit card account and then I have a double back up, you can have the credit card cancel payment and/or get a refund from paypal. Also with paypal the guy has no dealings directly with you, just paypal.

...and here's my take on this, FWIW

I'm almost certain to end up going down the Costa route for my MP3 400 (largely due to Jimc's recommendations for which I have great respect). But I'm still under warranty for a few more months so I don't want to run the risk of compromising the value of that guarantee just yet.

Changing just the rollers for a non-Piaggio product somehow doesn't concern me to the same degree and the Dr Pulley's get excellent reviews and seem like good value - even at full price.

I can't resist an even better sounding deal! I have heard and completely understand some members of this forum's concerns about a "too good to be true" offer from a very recent new member.

But...I'm a grown up, this is not a massive sum of money, I have a good feeling and I've put an order in to-day. I will, of course, post on here to tell you just what I get for my money, how long the product takes to get to me, whether it was well-packed and sent via a reputable carrier etc.

And, later on, I'm really expecting to post a full product review on here to let you know how the things worked in practice for me.
