Email address: Paul Wu ( "Paul " <paul@unionmaterial.com> ) from http://www.unionmaterial.com

Thanks Honda -Silver I saw the info and email of Paul Wu but I thought that was for tech help I did not know that he had a retail outlet.

Also check with www.mrp-speed.com they claim they are US distributor for Union Materials ... otherwise Paul Wu could ship directly to you.

Hi Chief

If you need any how-to or tweaking info when you get your new HiT Clutch contact me via PM.

I've had my HiT Clutch since summer and have had the "opportunity" to remove & reinstall it several times.

Paul Wu of Union Material (Dr Pulley) is the go-to guy for ordering and follow-up tech info.

As I remember, he shipped my Clutch kit via DHL and it arrived at my door in less than a week. The kit also comes with an extra selection (your choice of weights) of variator Sliders and/or Rollers sets.

Good luck

Tim thanks a lot for the offer of help on the clutch. I have ran into something interesting. While trying to find a distributor to order the Dr Pulley I talked to a shop owner in Springfield Missouri. He has a garage that speializes scooter and motorcycles and does a lot of clutch work. In conversation with him about ordering he ask me what was wrong with the clutch I have now. I explained that I was wanting one that was quicker on take off and his reply was the stock one was a quality clutch and to bring it in and we would change the rollers and springs. I thanked him and said I would get back. I wanted to put this out to the forum and get some input.

Chief, I was also talking to the Honda mechanic at my local dealer about tweaking the stock clutch and he said the same thing. The stock clutch is a very high quality unit and a little tweaking with a stronger springs such as a malossi would be all that is necessary if I wanted a quicker take off. Much cheaper option.

I sure wouldn't argue with that reasoning. It's definitely a whole lot cheaper than the HiT Kit, and if upgrading the springs to Malossi's gives you the increased clutch performance you need then you're good to go.

Changing the variator rollers to lighter weight rollers or sliders will give you the most bang for your buck and most noticeable performance increase. However, you'll still need to get that performance increase thru the clutch. IMHO the OEM clutch is the weak link in the performance chain. I opted to go with Dr Pulley's HiT Clutch, but that is not to say that upgrading the OEM unit with Malossi springs also give a big improvement too.

FWIW, I've got two sets of new Dr Pulley Rollers (26 gm and 24 gm) in factory sealed packs available FS.

Whichever way you go, please post how things work out for you.

The input from others here on this site is invaluable. If I can achieve the results that I want by altering the Honda clutch it will be great, if not then I will purchase a Dr. Pulley. I am a little hesitant to spend 400.00 plus on China made parts because my exposure to China made bikes and scooters have not been positive. My experience with Honda has a long track record of high quality and many trouble free miles so I am prejudiced. When I get off work in two weeks the testing will begin and I will keep good records so that I can pass on the information and hopefully save others time and money. Thanks for supplying the info on available springs I will keep them in mind. Till then thanks again David V.

Chief

Not to minimise your concern about parts quality, but the Dr Pulley stuff comes from Taiwan, not China. Huge difference in quality over Chinese crap.

Kymco, the Taiwan corp has been making (some) Honda engines and other components for decades. And the Kymco scoots sold here in the US are very good quality both design & dependability wise.

Tim

I looked at some Kimco's at STO and they looked great. I also talked to some owners that put a lot of miles on them and they were happy. I am glad that I was misinformed as to the origin of the Dr. Pulley clutch and like you my experience with products coming out of Taiwan has been good. Thanks for the info because when I try springs and sliders or rolers I will check as to the origin. David V.

Based on my experience with the rollers in both my Helix and Silverwing, I believe that Dr. Pulley makes quality products that are noticeably better than stock roller weights although I can't speak with any experience on the hit clutch though as I have used only Malossi on both the Helix and soon to be on the swing.

As to the Honda Clutch with added springs, the stronger springs will force the clutch to engage at higher RPM and should definitely help the take off. If your bike has some mileage on it, and you suspect that you have a good degree of clutch wear, a new clutch such as the malossi might be a good investment. I've recently purchased a Malossi Fly Clutch and I have read that they are supposedly a good bit lighter than the stock clutch which should help in reducing rotating mass (If anyone happens to have a stock clutch and can weigh it, I will weigh the malossi and we can compare to verify the claim). In addition to the malossi clutch, I purchased a set of the racing springs and installed the heaviest red springs in the clutch (This was a butt of a job until I figured out the best tool and method to use and I will document this at a later date in the tutorials along with the clutch install as soon as I finish the job when it WARMS UP!) As soon as I get a good day... I will install the new clutch on the Swing. The hit clutch reviews have been really good but it also seems like there is a lot of adjustment to get it perfect. The malossi supposedly works beautiful right out of the box and is much cheaper. Perhaps adding the stiffer springs as I have will give it comparable results to the hit clutch. I suspect most who install the Malossi probably leave the factory white springs in and never bother to change them thus lowering the RPM engagement. Before I install the Malossi clutch, I am going to run a quarter mile and 0-60 using GPS & Timer to see what difference is made. I hope I get good results.

Chief..... I've got an extra set of brand new white springs which are stronger than stock but not as strong as the red ones. If you would like them... PM me and I'll get them to you.

Unless you're drag racing I would think you'd want the clutch to begin to engage at the same RPMs as stock. But I would like it to bite a little harder than stock at that same engine speed. Just a little, or it would tend to "kill" the engine just like you popped a manual clutch too quickly.

On second thought, I suppose more "bite" pretty much has to be accompanied by a higher engagement RPM.

Hmmm......I don't want to wreck driveability in busy traffic. Better leave well enough alone in the clutch department. The HiT seems to be plenty adjustable, but will provide more solid engagement at higher revs. That might be the ticket. The Malossi sounds like more of a "racer's" clutch, and that isn't what I'm looking for.

The Malossi isn't necessarily a racing clutch. It can be if you want it to be. It basically comes down to the springs that you use in the clutch. It can be set up to engage at a slightly higher RPM (which is how it comes in the package) to a wilder and higher RPM by using any of the 3 sets of additional springs that you can purchase for it. The springs are the only adjustment for this particular clutch. I've installed my springs (the stiff reds) but am still waiting for a nice day to switch the clutches out. If we can get a day in the upper 40's to low 50's, I'll get the job done and report the results. If it makes the bike extremely "twitchy" and overly responsive, I will probably go to a milder spring (medium yellow or soft white). I definitely would like to see a good improvement over stock though. I used the red springs on my Helix when I changed clutches in it a few years back. It did make a nice improvement and it was not overly responsive. Then again...... the helix pumps out about 20 ponies as compared to about 50 for the swing so that is definitely an apples to oranges comparison so I can't make the same conclusion until the job is done and tested. What is interesting, is that the malossi clutch for the Helix could have the shoes adjusted in addition to the springs whereas the clutch for Swing is non-adjustable except for the springs. I am curious as to why Malossi has done this and have looked at other boards but can find no info on the topic.

The Martin Racing site is no help. I emailed them, and they directed me to their retail site: www.mrscooterstore.com It's as worthless as tits on a boar hog. I hate a bad attempt at a retail website.

Looks like the whole world is out of Dr. Pulley sliders. Their site has no mention of HiT clutches at all. I guess I'll have to break down and do it the old fashioned way and use the TELEPHONE, if I can remember how to use it.

If you go to http://www.unionmaterial.com then click left-side "Contact" or use email unionltd@ms14.hinet.net . They were very quick to respond to emails.

Thanks. I'll go to the source. That's always a good idea anyway. "Always talk to the Chief, not the indians."

I just got a quote from Paul at Union Materials (Dr. Pulley): $420 for the HiT clutch and a set of sliders if I "promise to post results" to this forum. (Which I intend to do, of course.)

I told him I'll order in 2 or 3 more weeks, when I can pony up the dough, and that if all goes well and I like the results I might consider becoming a Distributor. I'm disappointed by the lack of E-commerce know-how on the various web sites. Union Materials seems to expect me to put my credit card information in an email, but I'm not THAT dumb. I'll send a cashier's check via snail mail. But I think I see a niche market for somebody willing to put up a decent web site, or at least an Ebay retailer program of some kind. In fact, I'd be happy to just arrange drop-shipping from Union Materials for a nominal fee and just handle the transactions for them in a more "modern" way. I think they're really missing out on a lot of sales by not having a simple, clear "Pay here via secure connection" option of some sort and a clear cut, easily understood online catalog. Any any such enterprise should reasonably include some installation pictorials. It's easy enough to do.

Does $420 for clutch and sliders seem awfully steep to anybody else? The Malossi clutch is $200.

(edit: The $420 includes shipping from Taiwan)

A little bird whispered in my ear that I'd be paying for shipping from Taiwan, which would run well over $100. The price of the HiT clutch is probably comparable to the Malossi, but the shipping is a killer.

I'm not paying that kind of money to ship anything smaller than an entire Silverwing.

I'd really like to try the gadget, but the fact that there are none in stock in the USA is a deal killer for me. Their so-called "distributor" only carries the most popular ones, I'm sure. Nobody is going to keep a crate of Silverwing clutches in stock.

Dr. Pulley would do well to grant a license to manufacture the product in the US. Or at least Mexico, or something.

Meanwhile, I think I'll take another hard look at the Malossi and their rollers. They won't have all the benefits of the HiT clutch, but I'm sure that extra hundred-odd bucks will go a long way toward making me feel better about it.

As for becoming a Dr. Pulley distributor: I can now understand why they don't have any stocking distributors in the USA. No way I'm ordering a cargo ship full of the things to pile in my garage.

The internet makes the world look small, but it's really quite large after all.

Its a shame. Dr. Pulley really does make good products. They really need to improve their product distribution though. Mass Scoot and I had to wait for at least 2-3 months to get our sliders last year. The sliders are awesome. It is such a shame. It seems like stores like scooter trap are able to get maybe a few shipments a year and once they sell out... you have to wait till the next batch comes in. Mickey, I agree with you, the cost is a little steep for the Hit clutch... especially when you factor in the shipping. That is why I chose the malossi as well. I am still waiting for a warm day install it. I think winter will never end..... Keep trying to find some sliders though. I like the sliders enough to where I'd be willing to wait for them. Those 28 gram sliders are really nice and really help you out at speeds over 55 MPH by lowering those RPM's. I will see if I can find some for you and If I can.... I'll PM you. I have a few ideas where to look that have things for the Honda Helix as their parts/engines are used on buggies. They may have them for Swing as well.

Here are some places that claim to have the coveted Dr. P Weights.
Monster Scooterparts is not showing the 28 Gram Weights but the lighter ones but KSpowerline does. Most of the sites I looked at that have the Honda Helix/CN-250/Kart/Buggy only carry for that application and not Maxiscoots so those sights weren't much help.

Sliders ordered. Thanks! That's what an e-commerce site should look like. Plus they have some hard-to-find items (in the U.S. anyway) and their prices are decent. How come you could find them and I couldn't? Somebody needs to introduce them to Google.

I think I'll go with some slightly heavier Malossi springs on the stock clutch, which is probably still like new, and maybe a new belt if I still have problems. But I suspect that sliders and springs, plus some general cleanup and lubricating as needed, will get me though this season no problem.

I still need to get the Day-Long taken care of before the season starts. (Which, given the state of "global warming" this year, might be in August.)

I thought I had a line on some 28 gram sliders from KS Powersports, but after ordering them I found out he only has the 23s. The 28s are on eternal backorder. Sorry, Dr. Pulley, but I give up.
