Is it EVER a good idea to trade in a scooter for a larger one? What should I expect? Back in May of this year I purchased a brand new 50cc Bintelli Scorch from Grand Rapids scooter. I paid an out the door price $1099.99 (jason gave me a deal because I was buying two scoots at the time)... It was a great scooter, ran perfect and got me hooked on Bintelli scooters. Only bad thing was it was a 50cc and just didn't have enough speed for these long country roads where I live... Grand Rapids Scooters does not stock 150cc's so I had to look around for a 150cc... First I wanted the 150cc Bintelli Scorch, but all the dealers had in stock were the 150cc Bintelli Havocs. I contacted a Bintelli dealer in Wisconsin, Adell Auto center through email and negotiated a deal to trade in my scorch for the Havoc. I was given $800.00 trade in value for a scoot that had 1000 miles on it. So, I only took a hit of $299.99 which I thought was a very fair trade in price.... Now, keep in mind, I was trading in a Bintelli, to a Bintelli dealer... I'm sure if I had a TaoTao, Tank, Jonway, Dongfang etc etc I wouldn't have gotten the same deal... Anyhow, thats what I suggest is to trade your scooter in to a dealer who sells the brand of scooter you have. |

Buy the kit and not individual parts What kind of kit are you talking about? One that comes with a BBK, Stroker, Head, Clutch & CVT etc etc... Or by Kit, are you talking about something like a BBK? I have no plans on trying to piece together a setup where I buy an individual piston, rings, cylinder etc etc... I assumed you had purchased a BBK seperately from your stroker.... Can you provide a link to the "kit" you bought? I've been thinking about that.... I have emailed a few suppliers and got the same feeling that they just sell the parts, and don't really know what they're selling... However, there are also vendors like scrappydog who aren't just "sellers", they're also enthusiast and actually know what they're selling. I wish I could just up and switch careers... Here in America, there is a huge lack of competent Chinese scooter mechanics and a lack of suppliers that know what they're selling...... Thanks.... I already had the same thoughts that 63mm would be some really thin walls.... I have only been linking to 63mm BBK's trying to find information about the skirt height in these BBK's.... I think the key to running a stroker successfully is making sure there's enough "meat" there to protect the head-cylinder-case from eating the piston....... I would never use a spacer unless it was a racing engine... When the piston rings in my scoot get weak and can no longer pass a compression I'm probably going to beef the ole havoc up... It runs so awesome now, I wouldn't dare risk tampering a perferctly good scooter for 5~10MPH speed increase... This is just me planning for the future... It's almost winter here in Michigan, all I have left is the forums and window shopping for the goodies!!!  |

my bet is one is from a Kymco . I have the kit you need hereJohn TVNACMAN - Hey thanks for the link....! That's the exact kind of kit I was looking for... I've never heard of Kymco..... Is it a quality component? What's good about Kymco? |

My motor has the 62bbk which needed the case bored out and a 60mm +2.2 stroker crank and no spacers where required. What BBK? Who was the manufacturer? Not all BBK's have the same cylinder height... For instance, the Hoca 63mm bbk has a cylinder height of 92mm and the Samurai 63mm has a height of a whopping 95mm! |

BTW, what are the two different red lines on the flywheels in your picture? Why are they in different positions?

Use the flywheel that is currently on there, I have yet to see a flywheel with more than 8 magnets on the 150s. The important thing on the flywheels is to match the magnet position on the flywheel for the pickup coil when the flywheel is on the crank otherwise the timing will be off. Alleyoop Thanks! is that also true if it's a 6-magnet? I'm pretty sure it has an 8 pole because it has 2, 25 watt front head lamps.... But this is just a WAG till I yank the flywheel.... I was just wanting to have the parts on hand when I do the switch.... |

I still haven't been able to locate a bundle of the three items I'm looking for... I thought with all the people upgrading to HIDs and such there would be a bunch of packages.... Anyhow, I only need to locate the flywheel..They place I plan on ordering from has their flywheels listed as 6 or 8 magnet, But I can't find any 11 magnet flywheels... I know they have the flywheel I need, I just can't find it yet..... Anyone know what flywheel I will need to use with the following parts?:  Triphase Full Wave A/C Diameter: 87mm Width: 30mm Bolt Hole Spacing: 41mm Bolt Hole Diameter: 6mm Coil Wire Length: 20 inches Number of Coils: 11 Plug Style: 4-pin, female & 2 single wires  12 Volt Regulator Plug Style: 2 Plugs, 3-pin female & 3-pin female Wire Length: 6 inches Bolt Hole Spacing: Slotted 60mm |

with a 3mm you either have to use a spacer or shave down the piston. one or the other. 2 questions: So, are you saying with a +2.5mm stroker you don't have to do any mods to a stock GY6? Also, the HOCA 63mm has a taller skirt (it is 92mm vs the stock 89.5mm), does that mean I would have a combined 5mm of extra space for a stroker? The math works out if there's an extra 2.5mm of space in a stock GY6... The largest spacer I found is 6mm... If there's already an extra 2.5mm of space, 2.5mm-space + 6mm-spacer allows clearance for 8.5mm Taida stroker... Now I know Taida (and Samurai) makes a 95mm tall cylinder, but Taida's is only for the 57mm B-block... If you wanna go with an 8.5mm stroker on a 54mm, it has to be the 95mm Samurai or use spacers.... If I do go with a stroker, I will make sure to match it up with its corresponding BBK.... I do not want to use any spacers... I see them as a potential fail point..... What is it you prefer about Taida over HOCA? They're both Taiwan made I think..... I clicked on your link to Unique scooter parts, why do you not carry Taida products if that is your preference? I too like Taida's line-up, they have the widest selection and the water/oil cooled setups are the best IMO. |

I have installed every stroker for the GY6 150cc engine. Basically you have to use a spacer for 3mm and above. Reason is the piston will hit the valve head. Now there is a way around that but most dont know how to do it. You take the piston and have it shaved down and the valve seats made deeper. I have a picture of mine and i need to find it. Doing this yo wont have to use a spacer. It will work with both 3mm and 4mm. As for the 6mm I shaved down the piston and added a thin spacer. Issue i ran into was the 92 link timing chain i used was too long. stock chain would not fit. So i modified the chain tensior to make it a little longer and it worked great. Now for the 8.2mm is tricky. issue is because of the stroke is so long that during the down stroke the piston can come too far out of the cylinder and jam a piston ring causing failure. They do make Big Bore kits that have longer skirts or built in spacers specifically for the 8.2mm kits. Also when doing strokers you sometimes have to grind down at the oil pump area a bit so the rod does not hit it. So, you're saying you can in fact use a +3mm stroker without having to use any spacers? Or are you saying you can go +3 if you shave the piston? That's exactlly the kind of info I was looking for.... Care to share where you got your numbers from or is it just from experience? A few of the BBK's I found seem to be components for a larger kit.... The skirts are taller and have matching strokers and heads.... F or instance, this HOCA 63mm has a skirt height of 92mm (stock is 89.5mm), and the HOCA stroker is a +2.5mm.... 2.5mm + 89.5 = 92mm stroke... And of course the HOCA head ported to match a 63mm bore. |

I read your link.... That's awesome what you did to Alleys trike! I'm in Michigan which is not all that far away.... How much do you charge to rebuild one of these engines? |

As the thread title implies, I'm looking for a package/combo deal.
I need an 11 pole stator, matching flywheel and regulator/rectifier (The scooter has an AC CDI)....
I know a lot of people upgrade from 6, 8 to 11 pole for things like HID lights.... I would like to do that kind of upgrade to a scooter that I have (selling to my Father).... It's a 150cc Sunny (DongFang) and the stupid thing is not charging....
I went to fix it but it's not worth fixing in its present condition.... Damaged wires, factory wires that are about 22~24 gauge when they should be at least 18 gauge... Not sure how many poles the current stator has but I just can't get over how fragile the wires are... The main charging wire going from the regulator to the battery is seriously like 24 gauge... I'm surprised it hasn't just burnt up....
Anyhow, I want to get a real good, (name brand if possible) charging system....
I need a flywheel for an 11 pole (AC CDI) stator/magneto

Anyone have information about stroker kits? Success stories, failures? I've been searching pretty heavily about stroker kits and I've came across a few things I could use some help on.... For starters, a Stock GY-6 has a 57.4mm bore x 57.8mm stroke = 149.6cc. Stroker kits are usually listed as + x mm with the x being the additional millimeters. I.E. a GY6 has a stock stroke of 57.8mm. If you add 3mm to the stroke (60.8mm), you will get (57.4mm bore x 60.8mm stroke) a 157cc. Okay, so here's where my questions start rolling out... Just as the GY6 has a stock bore and stroke, it also has a stock cylinder height (at least I think).... Now, I haven't seen any numbers from a repair/shop manual, but I tried figuring out the size by looking up stock parts. From what I've determined, the stock cylinder height is 89.5mm. However, a lot of the aftermarket performance BBK's I have came across have taller cylinders.... I've seen them as tall 95mm (cylinder height).... That is a 5.5mm difference. First question: Is there any room in a stock GY6 to add a stroker without shims/spacers? - I've seen some that are as small as 2mm stroke. Second question: Is it the case that performance BBK's that are taller than the stock 89.5mm cylinder have more room for a stroker crank? --- To further this question, if the answer is yes, does that also mean that if I got a BBK that was 4mm taller cylinder than stock, that I should get a matching 4mm stroker? Third question: Does BBK stand for Big Block Kit, Big Bore Kit or something else altogether? Forth is about a specific stroker. It's the 8.2mm from Taida. Even though I have found this upgrade listed for a 54mm GY6, I've seen GY6 store owners say on these forums that they stopped carrying them because they were destroying people engines... However, you just never know if what you're reading is truthful or not.... Does anyone have any actual experience with this stroker kit? Taida GY6 +8.2mm Stroker Crankshaft (66mm)Specifications Applications: Stock Stroke: 57.8mm GY6 125cc Engine (152QMI) Stock Stroke: 57.8m GY6 150cc Engine (157QMJ) Stock Stroke: 57.8m Taida Stroker Crankshaft 66mm (+8.2mm)  |

To bring closure to this thread.... I have verified that the Bintelli Havoc 150cc has a 12-pole stator/magneto that is DC (CDI) fired, it produces 120watts at 7500 rpm.

Screw boring out the cylinder liner! A new jug + mated piston + rings + wrist pin costs about $70 delivered (and that for a decent high compression piston. Why fark around with anything else? As for stroker stuff --- ask Alley. I know nothing about that; he nows everything about everything scooter related. Does anyone know what the stock height of a gy6, 150cc "jug" (or maybe it's technically called the cylinder) is? I've been trying to find out by looking up "stock parts".... From what I've discovered, the stock 150cc overall height if the cylinder is 89.5mm. Now, some of the high quality BBK stuff such as Hoca and Taida I have seen has an overall height of 93mm...... That gives an extra 3.5mm.... In addition, the stock cylinder may have an extra mm or two........ Not sure, hoping alleyoops or someone else knows..... I like the idea of a stroker, I don't like the idea of shims......... |
