I have one of these 30mm pumper carburetters installed and would like to REPLACE THE NEEDLE VALVE IN THE FLOAT BOWL   Anyone have any idea what needle valve to get, or what float height spec to follow? |

An update on my experience with the little electric fuel pump that's been in use since last summer. Thing continues to work GREAT - much better starting than with the stone age vacuum pump. However - I think (not sure) the output pressure of the little pump is a bit too high for the little scooter carburetter and it's wimpy little needle valve. I'm noticing that if i have the ignition turned "on" but without starting the engine, fuel eventually gets pushed past the fuel bowl and into the carb. body. I'll no doubt have to change out the needle valve, but to ensure against continuing issues I've picked up a cheap little pressure regulator (about $20) that is dial-adjustable from 1 psi to 5 psi. The thing is made for carburetted VW Bugs - so anyone wanting to find one that's how to track it down. I have it set to 2 psi. Here is a pic of the thing installed:  |

Here is a pic of the variator I ordered . I'll post a few more pics later. I know quality is sometimes hard to tell from pics , but this k&s looks decent.  The good thing is that its def a different cast then the koso and dlh variators. It was about twice as much in cost also. Depending on were u get your koso. i WOULD BE REALLY HAPPY THE MANUFACTURER'S NAME IS IN THE CASTING ITSELF. BEST GUARANTEE YOU ARE ACTUALLY GETTING A REAL PART !  |

Your right , there are ways of finding out info " I carry one on my hip ,lol " no seriously , you can ask certain questions , but I think at this point most seller have no clue if the place they are buying from is selling a legit product so the info we will get will probably be bad, or by now , after being asked about the product over and over by multiple people they have learned just to lie to sell their product. Well, for instance, I have one seller on ebay I always buy certain parts from because he works with them and uses them and has experience and knowledge and often has good advice. Usually if I get a response where the seller just says "I don't know" or they give the long version of they don't know which can be annoying, I end up just never buying from them. I don't try to ask questions that may put them in a scenario to lie. Or I'll try to read between the lines if they have a long story about their product. Or if they simply say they are just selling it to make money, I just outright ask them, where'd you get it? lol Sometimes they just don't respond but yeah. That's why I say ask a bunch of people, the more views the better the picture will be. OK, but you understand that for illegitimate products (not sold through the manufacturer's distribution channel) the retail seller can't possibly find out what factory they really came from ... right? |

Lain - you seem to think sellers - especially ebay sellers - know what they are selling. I doubt that. Koso (as an example) is the designer and manufacturer. THEY know their product; others only read data sheets. Koso will sell to a national importer ("their agent in America) who is a "manufacturer's rep". They then sell to distributors, and these then sell to the retailer. the least knowledgeable of all is the retailer. If you want to know something about Koso products the best thing to do is to go to koso - which we are trying (hopefully they will respond). It would be great if engineers at Koso would work with us to identify counterfeits so the Koso name is not associated with low quality product (the "koso" variators we are seeing in this market are quite low quality and not consistent quality or design). Same with "Gates belts". I never said any of that man, lol. There is a way of going about things when you ask ebay sellers that will give you the story about how they came upon a product. When I shop around on ebay I usually message a half a dozen sellers or so about the same product that have different prices, asking if they know the manufacturer, if they use the product, how fresh is the product etc. I mean if you go right out and be like "yo is dis legit or should I do a 360 and walk away." lol.... I've been following the thread, learning more about how to spot counterfeits and such. So far I think you guys are doing an excellent job in inspecting the products and comparing them against other products. Just keep on doing what you'e doing! But Lain - ebay sellers don't KNOW and can't possibly find out! Koso sells ZERO variators (for GY6) here in America. They have no sales agent or sales channel. EVERY variator coming to us that is marked "Koso" is either a counterfeit or a real Koso manufactured product brought out the back door of the factory (often meaning it;'s a factory reject) and sold through some people, eventually being picked up by a retail seller here for sale to us (on Ebay or through a store). There is no way a retailer could trace this back to the source since that would mean finding out snuck the product out the back door - and no one will disclose that.Unless Koso gets involved and helps we just can't tell. |

Should contact as many ebay sellers of american koso as possible to get a wide eye view of the situation and be able to tell who's just stamping brand labels on stuff and who's going through the trouble of getting the parts from taiwan. TBA , how many of the eBay sellers are going to be straight up with us ? I doubt they are going to say their product is a fake Or that they get their Koso's from an untrustworthy source. Yes we may be able to catch a seller in a lie but tba , what is that going to prove at this point ? We already know that the Koso's being sold are junk . it seems as if everyone is selling the same crap product. When you sell a product with Knicks ,scratches and Gouge's in them , you should know that there is a problem somewhere. Tba if I received a product like that , I would never try to sell it . the product would be returned or if I cannot return it I would take a hit or sell them at a discount price and mention the imperfections. Selling a product like that makes your company look bad and throws out major red flags that the product is not legit. Yeah, George. It is certainly in Koso's best interest to defend their name and help identify what fraudulent product is being sold. Otherwise they will never be able to sell here because their name will have become associated with crap. Hope they will get involved. |

You should try and contact the Ebay seller, they should be able to tell you more than KOSO can  .

I've been looking at the performance variator from Scrappy Dog Scooters for 150cc and was wondering if anyone on here has had some experience with that one? Do you know what brand it is? |

That's interesting , they say they do not currently have any agents to sell them in the US , so does that mean all the Koso's being sold here are fake ? No necessarily. Koso is a Taiwanese company. Do they have manufacturing plants in mainland China? Maybe. It's a well-known fact Chinese factories - regardless of whose they are - often suffer from product "growing legs and walking out the back door". It's apparently a 'business-cultural' problem in the country that a percentage of product simply vanishes, to be sold by whomever to someone who then tries to make a profit reselling the stuff. Sometimes these are factory rejects; sometimes just normal factory production. The things we see on EBay or even from some retailers here might be the end result of this - real Koso product that made it's way to America NOT through a legitimate Koso sales agent. Or it might be stuff made by an entirely unrelated company - probably of a MUCH lower standard - that some enterprising person though he could sell at a high price simply by having whoever made it mark it to look like it was from Koso. Given the variety of weights and shapes of the supposedly Koso products we are seeing, my guess is this is most likely. I'm hoping Koso will respond further. It's in their best interest to defend their reputation, after all, and here we are willing to help. Heck - maybe we could even arrange for some retailers to work directly with them so they could distribute their product - their REAL product - here. I'm hoping Gates responds also ........... |

The start of what might become an interesting conversation with Koso Corporate offices - to help us with this issue:

Dear Sir:
Thanks for your mail.
We do have variator kit for the 150cc GY6 engine.
But we currently do not have agent in USA to sale this parts.
The question you ask for is for purchase this parts?
Bets regards,
KOSO TEAM

YES!
In USA the name "Koso" means very high quality and performance. Many people have interest in Koso product. But there is a problem. In the last year or maybe longer product with the name "Koso" come to many American customer that are NOT such high quality, and customers are disappointed.
We believe maybe there are not really Koso product, but are counterfeit. When I look at your product list on-line I do not even see variator kit for GY6 engine. Because of this I begin to believe ALL variator for GY6 with name "Koso" perhaps are counterfeit. Thanks to your response now I know this is not true.
We belong to "internet message board" for scooters and have started discussion to try to understand how to identify REAL Koso product from counterfeit. We try to use the weight. We try to use detailed physical dimensions. But we are not experts in Koso product and cannot tell what is maybe real Koso product and what is counterfeit.
As I said, Koso name is highly regarded here. But counterfeit products that use your name, but are low quality, damage YOUR name "Koso" because customer cannot tell this is counterfeit and thinks your REAL products are not very good. So I believe it is good for YOU to help us know what is "counterfeit Koso" so we can tell customers what products to avoid.
Is there a person we can send photos and detailed measurements to - person who can then tell us if the product we examine is REAL Koso product or only counterfeit? And is there way to know through you how to obtain REAL Koso product, even through agent in Taiwan or other country where you DO have agent?
Thank you for your kindness
RCQ

Will post results that come in.

Yep. DM
The best bet is to go to a 'reputable dealer", but even THAT isn't safe.
We have TWO recent examples now, both from top notch dealers: this possible counterfeit Gates belt issue, and another Koso variator issue, also possibly counterfeit.

Maybe at some point we will be able to tell what type of variator we have by weighing it or by how thick the face is , or both I have sent TWO emails to Koso asking simply if they make a variator kit for GY6 engines (their product list does NOT show any such product). The Koso people - being GREAT with customer support - have completely ignored both emails. |

OK, so I sent a message to Gates with a link to this thread. Hopefully they will respond (unlike Koso - which seems uninterested in supporting people and their products).

The Kevlar belts say power link also . from what I know the Kevlar belts have a model # that starts with 3. Like my 842x20x30 is a 30708 and the non Kevlar is 20708 and so on . I'll do a little research and get back to you . Anyway, I am not good at subterfuge so I just asked the seller about the issue and referred him to this thread. Seems like a good guy; answered quickly and did some research. I'm not saying the belt isn't a counterfeit - as we have seen with variators evewn the BEST sellers can get and move product that isn't genuine. here is what he said (s responses):
First:
"We have been selling these gates belt for a while now and getting them from 3 different suppliers and it's never been questioned before.. They have always looked the same to me, until recently I did notice the new belts are now coming with the Made in China and the part number on them. From what I heard gates was only producing them for the scooter manufactures in China for use on the manufactured scooters and that was the reason why at first they did not come with the slip or made in china on them.
A few years ago we called gates USA main distributor and they did not have stock any of the common scooter belt, keep in mind that was over 4 years ago, so now maybe now they are since the market has grown. We don't actually go to the manufactures door step so I can't tell you for sure since anything can happen through the supply chain. But I can tell you that we have never had any complaints about the gates belts we are selling. A few year back we got an order for a gates belt and it was shipping to Gates USA head offices. We thought that was strange and of course got a little nervous about it. We never heard anything of it after that. We just assumed maybe they wanted to inspect to see if it was really a belt from one of their manufacturing plants.. "
Second:
"I was able to find a link to the gates manufacture in China ( www.gatesunitta.com/en/scooter-belt ) . As you will notice they have different markings on the logo and use the R (not TM). Also you will notice that the slip/packing is not the same as some of the other slips I have seen locally. I personally think they change the logo, print and packing to the buyers requirements. So in other words it seem to me it would impossible to determine if it's real or not with just packing and logo alone.
I found the link through this site.
www.gates.com/regions/asia-pacific
then click "Industrial Power Transmission"
Hope this helps.. Let me know if you have anymore question or concerns.. "
So now I have no idea what to make of this.
Thoughts? Really - I need help with this.

The new Powerlink belts arrived - well, most of them. The Kevlar from Miami came yesterday; the GY6 sort of came (I ordered 2 and he messed up & shipped only 1). Anyway, spare belts in hand. Here is a pic of the 2 belts --- the kevlar on the bottom. It shows no mention of "Kevlar" ---- I emailed the seller yesterday thinking he had sent a regular Powerlink by mistake. His response was: The kevlar has yellow cord inside the belt. I DO see a beige or slightly yellowish cord on about 1/3 of the belt. Is this what you guys have been seeing with kevlar belts?  THIS IS A POLITICS-FREE THREAD BECAUSE WE ARE, OF COURSE, POLITICALLY CORRECT FROM HEAD TO TOE !!!!    |
