Does anyone have a source for the 4 pin headlight wiring connector that plugs into the switch, on the handle bars, on a 2008 Roketa Bali Mc-13-150? Can these be sourced locally? Don't want to have to buy a whole new harness. Thank you. Can you post a pic of the plug you need? |

That is cool I know all about the B cases that is why I asked the question to make sure you know what in the hell is in your scoot before you spend money and find out it will not work on your motor because not to many dealers will refund for wrong parts. Just trying to help you bro, with whatever you decide to get, since you been asking lots of questions it is obvious on some of these things your not that knowledgeable. I also see you are getting many different flavors to your questions and that does not help, it does confuses things more. Alleyoop I know you're just trying to help and I am most appreciative.... I wasn't providing the information I did so I could argue/debate... I provided the info to show you where I'm getting my info and sources from..... If anything is wrong on my part, I welcome being corrected as thats half the reason I go through the effort... Yes, I've been asking a lot of questions because I find these little GY6's most fascinating! The fanfare and all the aftermarket parts is something I wasn't aware of when I purchased my scoot... However, even though I'm not all that "knowledgeable" yet, over the course of this winter, you will see that radically change. I do have a basic mechanical skill set, full shop loaded with tools and I don't just ask questions on the web  I also have a Haynes manual to get hard numbers... But, I will still be asking lots of questions too! For as long as you guys put up with it that is... Anyhow, sometime meaning/context etc etc can get lost in text... If my post aren't coming off as appreciative, just know that I am... |

Where in the heck did you find a 60.3mm for the B case? Even other stroker cranks are far and few between for that motor. Most strokers come 2.2, 2.5 etcc.. Are your sure you have a B case what does the studs measure crisscross wise which is the only way you will know without pulling the whole top end off. Take the Valve cover off and measure the studs center to center crisscross that will tell you if you have the big B case or the smaller B case with just a top end and length difference. Alleyoop Did you not click on the links I provided? The 180cc is plastered all over the performance websites. Strokers area a dime a dozen and all over the net as well.... Very easy to find..... And no, I do not have a B case, the 180cc is the B case....... There's a lot of confusion about the "B" case motor I have found and it took me quite a while to get it sorted out.... For this thread, we will call the b case the one with the 57 stud spacing.... First off, there are a LOT of different b cases...Short case, long case and extra long case. There's a lot of misinformation that says it's only the 16" extra long case that has the 57mm spacing... Not true! Is what is true, the ones that have a 16" wheel require an oddball crank...... But, there are also b case motors that only have 54mm stud spacing.... The 180cc kit I linked to does have 57mm spacing, but uses a standard gy6 crank, meaning I can use a GY6 stroker.... Now, Keep in mind, Taida also makes their own gy6 232cc capable engine, it can use the super 8200 crank (like the 16" b case") and a few others that will not work with this 180cc kit..... It would take a long time to explain all the differences |

Got to ask what kit is a 180cc Kit and which stroker to bring it up to 188cc. for 150cc GY6 Chinese Scooters That's the 180cc Kit... It does use a 63mm bore, but this is a "b" case motor and can accommodate all the way up to 67mm should I decide to bore it... Awesome thing about this kit is everything is pre-bored... No machine work required. One more awesome thing about this kit, the cylinder is 2.5mm taller than stock meaning no spacers required. Next up, stock stroke is 57.8, so we add this +2.5 Hoca stroker to bring it up to a 60.3 stroke. 63mm bore + 60.3mm stroke = 188cc's BTW, if you have a 62mm bore, with a 60 stroke, you only have a 181cc, not 182cc. The equation is quite simple to calculate the displacement. Half your Bore (62/2=31), Square it (31x31=961), multiply by pi (961 x 3.14159 = 3019.070796460177), then multiply by your stroke (3019.070796460177 x 60mm = 181144.2477876106 )and move you decimal... 181. 1442477876106 Viola... 181cc *EDIT; Got to thinking about it.... You may have a +2.5mm stroker which means your at 60.3mm stroke... Doing the math at 62mm bore x 60.2mm stroke will bring you up to 182cc..... Otherwise you're at +2.2mm stroker and that puts ya at 181cc. |

Ok, so I've been giving serious consideration to a GY6 180cc Power kit, adding a stroker to bring it up to 188cc...
My current carb is 24mm cvk...
First question, could I upjet my current carb enough to work with this size of engine? And if not, what size of carb would you recommend?

Here is what the seller emailed me back with the wiring. Alleyoop Thanks Alley! That's the exact info I required. |

Let me ask you guys another question about the 4-valve head.....
Do you consider the 4-valve to be worth $250~450.00 USD (price depending upon brand) in the event that you are NOT building a racing engine?
My goal is to beef my engine up, but I'm not looking to go any faster than 70 MPH. When I purchased my scoot, it went about 60MPH, by the time I got 500 miles and she was well broke in, I could (GPS verified) Get my scoot up to 62MPH, reliably too. I only weigh 150lbs. But, I've since added an XL trunk, saddlebags, carry about 20lbs tools and supplies, and have a windshield now... This brings the speed down on hill climbing, take off and even hurts top end by about 3~4MPH
Now, I would like to get back up into the 60's, maybe even 70 MAX...
At the same time, I want a reliable long distance cruiser and not a racing engine...
All the feedback I've received about the 4-valve head has been pretty encouraging so far.... Now I just need to find out about reliability,,,

The tacho does work, you have to join the red/w stripe wire to the red/w wire that joins to the CDI unit for it to work... you may have to extend the length of that wire to reach where the CDI is. Dont worry about that oil light wire, its no use.. well for me anyways so i didnt bother with it Thanks for the info!!! Ya know, we may not have gotten off on the right foot, but you sure are turning out to be A-Okay in my book! Thanks for taking the time to try and help me hook this thing up!!! |

In reality the 2 big valve head flows better than a 4 valve head. And who in their right mind would crank the motor up to 11-14k  . At those rpms you have to then worry about the case not holding up just like a hotrods block, put to much strain on the crank and the block will give the crank will come through the case My .02 on this unrealistic undriveable unreliable piece of work  Are you talking about Cyborgs blueprint or the 4 valve in general? |

Some of the wire colours have completely faded and i cant make out what some of them are lol.. bloody brake fluid leaking from the accident. Here are some instructions i was sent from the seller. The oil indicator lamp will light on every 1000KM, if want to turn off this function, at ODO mode long press ADJ button, you can turn off the indicator lamp. I have been wondering how I'm going to deal with that oil indicator. I wish I could find what this speedometer is cloned after and what it originally went on. All these digital chinese speedometers are generic copies of an actual name brand part. If I could find the original, I could find the wiring diagram.... This speedometer could be for a 2 or 4 cylinder motorcycle for all I know... If that's the case, the tach will never work with my single cylinder scoot I don't think. By the way, did you actually get all the functions working on your speedometer? |

Actually, I may have just figured one more out.... The Yellow/Green... That's the same color that goes to the starter relay.....
Perhaps the Brown/Black is actually the oil indicator.....

I emailed the seller for instructions and or some info on the wiring, see if he response. Alleyoop Ther's a few sellers offering the exact same speedometer. This is one I purchased from..... Please read the entire auction, the seller seems to be on the ball and ready to offer up advice, problem is, he doesn't know how it wires up himself.... Take note: In the auction, he list line function (wiring pinout) with only 8 wires, the plug actually has 9 wires. During our messages, he tells the function of 10 wires.... I have contacted the seller, here's a copy of our msgs..... I think I figured out one more wire..... The yellow w/white stripe I think goes to the the fuel sender... Thanks dazza!!! Now, I just need to figure out the Yellow w/green stripe which is i think is for an oil sender that my scoot doesn't have (may need to figure out how to terminate or find the sender. And the the Brown w/Black stripe ... Can't figure out what this one goes to either.... |

Hi all, I've seen some 4 valve heads available for the GY6.... has anyone tried them, do you have a scoot that came from the factory with this type of cylinder head? What are the pros/cons of a 4 valve vs 2 valve setup?  |

I also have a Haynes manual to get hard numbers... But, I will still be asking lots of questions too! For as long as you guys put up with it that is...
