I have learned alot about these 139qmb starters recently in the Project Yellow Fever build. 49ccscoot.proboards.com/index.cgi?board=builds&action=display&thread=3060Many of you already know these GY6 50 starters are not created equal. These 'Haiwei' starters come on my new factory 72cc bikes and are very similar to the polaris 90 starters here: www.ebayMy 72cc starters have the same 'W' looking symbol that is in the first picture (in front of the part number) and 'Haiwei' on them. They have the good threaded post instead of the hole like on the cheap starters: www.ebayMy starters:    I am bummed that these bikes with the good 72cc motors and these good starters are all but gone  I took one off a new bike i've been cannibalizing parts off of to put on Yellow Fever when I first built it since I was having cranking issues. With this good Heiwei starter she cranks up with just the one 90 cca battery in the stock location. A standard cheap-o starter like the link above it needs the battery i put under the seat too in order to turn over. Anyway I sent the seller a message to see if he can get Haiwei #201012 but if you see it anywhere please post it here...thats the good stuff! |

After looking at it closer the 'W' looking symbol is the combination of an H and a W..I assume for the brand name: Haiwei
I am thinking the guts inside the starters I have and the polaris 90 haiwei starter on that link are the same maybe but i dont know. Its an obvious better quality than the standard GY6 50 starters anyway. Yellow wouldnt even crank with a standard GY6 50 starter....but cranks with this Haiwei starter.

Yeah the pic does say Haiwei on it, but the ad says "Yamoto" I would guess the photo might be a generic picture they uploaded and may or may not be the brand you actually get. What about the BENDIX? any better options on those? |

Why not just email theguy and ASK exactly which starter he will ship? Or specify that you only want the Haiwei brand as pictured if he has it. The picture is likely only a generic one he had handy, and as long as what you get is as represented (he doesnt spacify its a Haiwei) then you have no recourse if the starter turns out to be nothing more than a duplicate of the cheapest stock Chinese starter you get from the factory on your scoot. |

The names he's using to list are just to get more hits from people searching for different scoots. I think, and hope, you'll get what's pictured. Let us know though. Good info.

Could be, still, I would email the guy and ask/specify to make sure you don't wind up with the same cheaper factory installed junk it's replacing, it's likely not returnable and ebay likely wont do a thing since it's not being sold as a HaiWei starter- that's $40 for the starter and shipping. I think the bendix is the other part that's uber cheap, mine has never engaged on the clutch gear properly from day one, it always takes "bumping" the starter switch 1-5 times to finally get it to mesh. I've had it apart and it all looks fine, put a smear of grease in the bushing, but theres no pattern to it, sometimes it catches on the first try, but most of the times it takes at least two before the gear on the bendix meshes properly. When it doesn't the starter just free-spins. |

That's a good and easy idea Wolf. We posted about the same time this morning and I didn't notice it.
I've had trouble with bendixes as well, but never heard of anyone mentioning good or bad ones. I do know sometimes they can be picky about spacing with the CVT cover. When I had a 4T I played around with shims on the bolts by the bendix to get the best results. Prob the only reason the CVT gasket may matter on those scoots.

some of these 139qmb bendixes are longer overall...and have longer teeth. I have 2 here on the bench and the measurements are certainly different...so obviously they are not all created equal either. i will work on that too.
I asked the ebay seller about the starter...no reply yet.

the teeth on the one on the right are longer as you can see. it has a diamond symbol with a WH inside it. the one on the left has a Y inside it. I dont know what it all means. This will probably be more challenging to figure out lol. The one on the right does as you say Wolf....so i replaced it with one just like the one on the left and problem solved...which is the opposite of how i thought it would work. seems like the longer teeth would engage better.

Prob the only reason the CVT gasket may matter on those scoots. Looks like we did hehe! I've reported my starter issues on another forum and at least a few others said they had the same issue, so I started to figure maybe it's just a normal part of the particular design, it IS somewhat on the crude side compared to automotive starters. But this really CANT be normal, even if I'm not seeing any damage to the teeth from the "missing" the meshing. You may very well have hit the nail on the head about the cvt gasket that a lot of people say does nothing, I've responded to that by mentioning the Chinese, actually anyone who builds machines are not in the habit of designing, producing and installing parts that do nothing. It's there for a reason, I had assumed maybe to keep sand and dust out and keep it alittle cleaner inside, but I never considered the clearance in the starter shaft to the bushing, and when you think about it, with the gasket gone the cvt cover will move in slightly, that small amount might be just enough the starter shaft bottoms out or can't turn properly or engage fully. I do have my gasket intact. |

The one on the right does as you say Wolf....so i replaced it with one just like the one on the left and problem solved...which is the opposite of how i thought it would work. seems like the longer teeth would engage better. OHH!!! now that's an interesting observation with them side by side! that one is an easy one to miss. I have looked and seen both 9 tooth and 10, the TT50 has 10,, do both bendix' have the same number of teeth, but one is just longer than the other? I would think the longer teeth would engage better too, but not if there is not enough clearance for the "throw." The way i see it, is it's almost as if the teeth that are to mesh when starting are not bevelled enough, and so what I'm thinking of is a flattened or squared end of the teeth hitting the backside of the clutch gear and free-spinning. If they had the correct amount of bevel to them coming more to a point, the gear teeth would sort of "knife" in and move the gear or bendix just enough the teeth mesh. I should look at mine again soon and take a measurement of the teeth and report back as to their length with calipers and maybe take a photo. Are both of your bendix' exactly the same O.A.L end to end? and it's only the teeth that differ? One of them almost seems slightly longer OA than the other but it may be just the photo. The WHOLE problem seems to be in the bendix itself because my battery is always fully charged, the starter cranks real fast, I just don't see any deficit in either. However, I did just now purchase one of the Haiwei starters on ebay since I don't trust the stock starter anyway and its one thing I did want to replace but not with the same factory installed junk, which till today I didnt know there were any other alternatives. |
