can i use 16 gauge on everything? Yes, BUT..... 16 gauge is going to be harder to work with and if you intend on using the original plugs, some cases the wire will be too thick and not fit in the plugs. I would use 18 awg to rewire the scooter and 16~14 awg for your main battery &neg and your solenoid circuit. 16 awg cost more than 18 awg and you will not have any added benefit. Keep in mind, most of your GY6 scooter circuits can get away with using 22~24 awg wire because the individual circuit draws so little current. 18 awg is more than adequate for the main harness. |

how many mm can the stroke be extended on a stock GY6 150cc, without having to add spacers/risers? If I recall there's either 2, or 2.5mm.... thought you need spacer for all... or perhaps just extra gaskets. You don''t need a riser/spacer/extra gaskets for some stroker kits. Alleyoop has a 60mm crank (which is +2.2mm) and he doesn't have any spacers. Take a look at the picture i'm including. The space called the "clearance volume", that's the space I'm talking about. A stock GY6 150cc I'm pretty sure has a clearance volume of 2.5mm... When you you fill that gap, that when you create what's called a "high compression" engine and it's when you're best served with a forged piston.  |

Dmartin95,NICE BUY!!! No, GREAT BUY!!!For your needs, I don't think you could have made a better choice! And, OOOHH! that windshield... It looks VERY much like the GIVI shield on my Kymco. If it is, you will learn to love it! Mine does make a "pocket" and you can hunker-down BEHIND it, OR sit up tall and look OVER it depending on the individual situation. And the BEST part... It keeps my HANDS warm down to below 50 degrees!!! Woo-HOO! NO bike I ever had before was comfy at 55 degrees! The performance of yours seems to be even BETTER than that of my old 250. The capabilities of new engines is AMAZING! A top-end of  should yield a 75 mph cruise. THIS one may be Vespa's worst nightmare... LOL! If it has the torque to go with the speed, you should be able to cruise the freeways at 5 mph MORE than my 250. THAT is about PERFECT while still being a nimble in-town ride! Double Woo-HOO!!!
Please DO keep us posted as you get it broken in and regularly ridden. I have a feeling THIS scooter may be THE answer to what  % of this site's riders are REALLY looking for: a 150 size scoot that is nimble, easy on gas and can STILL push over 80 mph... They're a little pricey, but if it can do all THAT, it's a REAL bargain, and it will be hard to keep them on the showroom floor! You got yourself one SWELL all-purpose ride there! ENJOY IT!Leo in Texas Leo, thanks! I too feel like I made a great buy... I was wanting something that performs like a 250cc but yet is nimble like a 150cc and yes, the S MAX fits that bill perfectly. I went out for another little cruise the other day and got into the throttle more than I should have but I just couldn't resist. I was up to 74 MPH and was only 7200 rpms. The engine still had a lot left. This is a high RPM engine and the tach doesn't redline until 9500rpms. Hills are now a joke and the S Max takes a hill as if you're on level surface. This is an amazing machine for only being a 155cc. |

Great thread gang! Lately I've been figuring out how to identify counterfeit Kehin carbs..... With all these counterfeit parts on the market I've discovered there's only one way to be sure you're getting real stock.... That is buy from a reputable dealer (and even that's not always a guarantee)

Yes, you are right. For 59-69$, it's better to buy a new crank. I have a question about what i need to do after i'll end the engine break in. Do i need to recheck the torque on the engine head nuts? I found this thread to be most informative. That's awesome you kept us updated. You showed a pic of the puller you used on the bearings to remove them, but what about install? Did they fit right in or did they have be pressed in? Also I'd like to say Job well done! You did a good job. |

There are many standard carburetors in brand of “KEI★HIN” exported to USA is not the Keihin brand owned by Japan Keihin. It is from the company Fujian Youli Carburetor Co., Ltd. It is popular over there just because buyer mistakes it for Japan Keihin. There was lawsuits between Fujian Youli and Japan Keihin, which can be found on line (http://www.law-lib.com/cpws/cpws_view.asp?id=200401482826) Hey gang, thanks for the feedback. I've done a great deal of research into the Keihin line-up of carburetors and discovered that a genuine Keihin is pretty easy to identify. Genuine Keihin are stamped K T under KEI★HIN instead of "standard of Japan"  There's a good post on 49cc.com about it: LINK |

Very nice looking scooter! I'll be curious to hear how that windshield works out, it looks like it's open underneath, so please let us know how well it protects you. Also curious to what you paid, if you don't mind telling us. The windshield is kind of weird.. If you sit up and ride normal, it blocks about 75% of the wind (based on what my hands (unprotected) were feeling. But as I mentioned, It was cold, so I tried ducking down behind it and it was if there was no windshield at all... I think the way it's designed is that it aerodynamically creates a "pocket" in which the wind is diverted away from the rider.... As to what I paid, with Sales tax, title, registration and dealer fee's it came to an even $4500.00 out the door. Worth every penny though IMO... I love my Bintelli Scooters... They have been outstanding machines. However, I needed something that was faster than 62 at WOT. I wanted something I could easily cruise at 70MPH and I don't know if there are any Chinese scooters I would feel comfortable riding at those speeds. I purchased two Bintelli Havocs last summer. I wanted one as a back-up so even if my scooter went down for repairs, I had another to hop on and twist'n go.... I also wanted something for my company to ride. Sometimes I didn't know if people were coming over to hang out with me or just go riding with me.... LOL  ... It's what made me think of getting into the scooter rental business. Anyhow, 1200 miles on one, 300 on the other and zero problems, always instant starts. When it comes to "Chinese scooters" I think Bintellis are top notch. Not sure if I'm going to sell them or rent them.....I really don't want to sell them because I think they're awesome machines. |

I have been drooling over the new Yamaha S Max ever since Yamaha since the email notifications of their new line up. The S Max features a water cooled, 4 Valve, EFI 155cc engine. Capable of reaching speeds of 75~ MPH depending upon rider and road conditions. Has front and rear disk brakes One of my local Yamaha dealers had me on their email list to be notified when they came in. Reviews were one thing, seeing it person was something different altogether. I was sold the minute I laid eyes one her. We also put in an order for my wife to get one. She's getting the Titan Matte color. It was only 40 degrees out so I didn't for that long of a test ride, but it handles awesomely! I wasn't able to test high speeds and cornering that much because it's in the break in period, but I will update this thread as my adventures continue. Anyhow, here's some pics of my new ride:    |

I have a rectifier issue and need some help. I have a lithium battery on the scooter and it went dead. I was told that I had a rectifier issue and bought a new one which I thought was the right one. It charges the battery and the output is where it is supposed to be. My problem is now that the headlight doesn't work. I am enclosing some pics as I when it comes to electrical, my skills are minimal I have a 6 pin OEM (the bad one) rectifier  with the following wire configuration And the new one with this wiring  Both are six pin with 2 separate connectors(2 vertical prongs and one horz) with one connector with 3 yellow wires, which is what runs the headlight and the other for charging the battery and whatever else. I hooked up the new one and there is a considerable difference in the voltage output but the headlight doesn't work. I assumed that the 3 white wires on the new one where the same as the three yellow which handle the head light on the old one, but sigh, it doesn't work. Any help would be greatly appreciated. totally stuck. I searched high and low to find the right 6 pin configuration (2 connectors with 3 wires each) and thought I bought the right one. Doesn't seem to be the case. The only photo I could find with the exact wiring setup was listed as a 11pole 6 pin but I hardly think my scoot came oem as 11 pole and I haven't taken it apart at this point to verify. And it is only available on ebay and I have issues with using paypal (hate them) so this is not a purchase option for me. Thanks in advance for your help Hi dickyh. Partsforscooters.com carries the stock Regulator/Rectifier for your scooter. They sell it for $24.99. Here's a link: On some scooters, the R/R activates the headlight. If your headlight no longer comes on after switching the R/R, i'd say you need a different R/R. But take note, switching the R/R to a new one may not solve your problem with the battery losing it's ability to hold a charge. Some batteries, such as Lithium and glass mat, even some AGM are designed in a way that charging them too fast will actually damage the battery. For example, selecting 10 amp instead 2 amp ona trickle charger could damage it. Well, it could be the case that your R/R's charging circuit pushes too much current into the battery too fast. You may want to just go back to a stock battery and put your old R/R back on. Get a 7~9ah battery (around $30.~40.00) ------------------------------------- What are your voltage readings (before and after the R/R swap if you recall)... And TVnacman is likely correct. That looks like a three phase stator. However, yellow, white and pink are various A/C colors and it could be you have two yellow A/C inputs from the stator and one A/C out to your lighting and auto enricher circuit. More than likely it's three phase input. BTW, 11 pole are not the only three phase,. Your scooter may have a 12 pole stator. Anyhow, like John suggested, try and get a pic of your stator plug (It's located coming out of your fan shroud) and also tell us what your voltage readings have been. |

So I've had my Super 8 150 for about 6 months and I'm realizing that I should've gone bigger. I love riding, but it is kinda frustrating not being able to get on the highway at all. Or struggling to keep up with traffic when the speed limit is 50 and there's a headwind or a hill. I really don't want to make the same mistake and get something too small, but I'm not sure how big I want to go. Most of my riding is in the city, and I don't want to lose the great maneuverability of my 150 for speed I'm not going to use that often. I would like to take it on the highway with no problems but I don't know if I need something that's going to go over 100mph (I've never even wanted to drive any of my cars that fast). I am concerned that if I get something that tops out around 80, that I'm going to wish I had gone bigger just so I could cruise at that speed and not feel like I am running my scooter into the ground. I just started looking but I've found a 2006 Piaggio BV250 for $2000 (http://washingtondc.craigslist.org/mld/mcy/4906375293.html) with only 700 miles and a 2009 Yamaha Majesty YP400 for $3800 with 2700 miles (http://baltimore.craigslist.org/mcy/4930233427.html). I'm hoping one of you guys could give some insight on if I should even consider moving from a 150 to a 250. Or if I should just look at 300's and above. If your looking for something that's nimble like a 150cc but fast like a 250cc, you may want to give the new Yamaha SMAX a try. It's one of their new line up for 2015. $3690 MSRP. Top Speed is 85MPH. It's only a 155cc, but it's fuel injected and 4 valve.... I'm going to get one myself here pretty soon.  |

If you need any cables built when you do your upgrade, give me a shout. Around $10-25 per cable/harness... depends upon how many feet of cable and the amount of plugs/terminals used. Is this offer for anyone? Wouldn't mind a simple harness with head and tail lights. Maybe turn.... Let me know. Thanks Edit: Sorry; maybe shoulda PM=ed. Yeah... I can build ya some cables. You can see in the stator video, I make quality cables and use stock plugs so you do no splicing or soldering. You have to be able to provide pictures to illustrate exactly what you want... I can also build harness's based on diagrams. |

Yes, you will need to replace the flywheel if you upgrade. 6 magnet flywheels will only work with 6 pole stators..... However, with the 8 magnet flywheel, you can use it with 8, 11 or 12 pole stators. IMO, if you're going to replace the stator, go with an 11 pole if you have an AC coil, 12 pole if you have a DC CDI. The 11 and 12 pole are both three phase and the stators cost about the same as an 8 pole.. Also, if you have a 6 pole, chances are your R/R will need to be upgraded as well. 4 pin R/R are single phase,.... I heard the flywheel is the same for the 6 and 8 poles., I read up about them a while back . when it comes to the 11 poles , many have problems and have to rewire some of the electrical. Someone actually sent me their 11 pole stator and flywheel because they could not get it to work . I haven't tried it yet . Did you see my 11 pole stator upgrade video? It's very easy to upgrade your stator... Yes, there is a little re-wiring but it's only a matter running three wires from the stator to the R/R. and you may need to rewire where your lights get power, but all this is very easy. I went the extra mile and bought all the stuff to make GY6 harness's but one could do it on the cheap by soldering or using cold fusion crimp connectors. If you need any cables built when you do your upgrade, give me a shout. Around $10-25 per cable/harness... depends upon how many feet of cable and the amount of plugs/terminals used. Oh, and you're free to "read up" all you want on 6/8 magnet flywheels, but you can NOT use a a 6 magnet flywheel with a 8 pole stator. |

Alright so I took off the flywheel of my 150cc scoot ,and noticed that a small metal piece was on the wall of the flywheel. Which means the flywheel has scratches and small dents in it. How did it get there and what is it? Shaped like a half moon. Anyway, I also noticed that a lot of grime was on the stator. (Its a bad stator) My stator has 6 copper leads and I was wondering could I upgrade it to 8? I already picked one out. Also do I have to get a "8 lead flywheel"? I dont think I have to. Pics coming soon. O and Alleyoop, I replaced my fork oil no problem thanks. Yes, you will need to replace the flywheel if you upgrade. 6 magnet flywheels will only work with 6 pole stators..... However, with the 8 magnet flywheel, you can use it with 8, 11 or 12 pole stators. IMO, if you're going to replace the stator, go with an 11 pole if you have an AC coil, 12 pole if you have a DC CDI.
