A while back I asked you all for help getting a 150cc to start. I ended up getting it going all and well, but a while ago it started doing this thing where when I'm going up a steep hill, it'll make a "clunk" sound and I'll feel a physical kick in the motor, then it dies. It starts back up, but it feels like it turns over weird for like 3 cranks then something seems to catch then it turns over normal, starts back up, and runs fine again.
Anyway, I said f*ck it and bought a brand new 150cc motor still in the crate from a close friend. I know its untouched because I was there when it was delivered to his house. He had plans, but never did anything with it so it sat in the crate for over a year. My problem is, the "bad" motor is DC and the new motor is AC. I put a new stator in the DC one when I first bought it, and it has less than 100 miles on it since then. So the stator is basically brand new. If I pull the DC stator and flywheel out of the old motor and put them into the new AC motor, will it basically become a DC motor? I don't want to have to rewire the whole bike

150cc trouble

ac and dc cdi are definitely not interchangeable. your carb issue is probably the enricher you're talking about, and I've had mine unplugged for the entire summer. my 150cc starts right up without it. when it gets cold, I will have to use it. it makes a rich mix for immediate startup, then leans the mix out. I think it does it every time you start which results in wasted fuel and extra carbon buildup. I hate carbon buildup. Yes, I'm aware the CDIs aren't interchangeable on different voltage types. But I wasn't sure when I was basically done with the project that the last owner had put the wrong CDI on. I had no paperwork or model for the scoot so I had to wing it. I figured out the circuitry by completely unwrapping my harness and tracing the wires. I'm a licensed electrician so as soon as I traced the main power to the CDI and realized it was a direct connect to the battery, I understood the problem and promptly fixed it. Just sucked that I had to tear everything apart to find out how it was wired lol |

Guy I bought the 150cc from, sold it to me with an AC CDI hooked up which I thought was stock because he told me everything was. After replacing everything electrical to brand new and still having the same result, I finally tried a DC CDI and it worked. Talk about a major facepalm. :/

Hey guys. Does anyone know ehat the heck a carburetor controller relay is, what it exactly does, and if it can be bypassed? Part ID: XDZ 080704 www.vmcchineseparts.com/products/carburetor-controller-relay-4-pin-xdz-080704I learned how to weld recently, and the first thing I did with that power was chop a 150cc frame so I could swap my 50cc up without having to get new plates and such. Everything went fine but I'm not getting spark on this motor. Parts replaced: -Stator and pickup--this thing has a 12 pole stator. Yes, 12. -CDI Box -Spark Plug and Wire/Coil The voltage regulator in my kit wasn't compatible. The wiring harness is stock from the 150cc motor and frame I got for this project. I've been tracing wires for hours looking for a short, haven't found any. I've bypassed my ignition switch and tried it that way, same result. Everything seems to be wired up correctly. It turns over, pumps fuel, all the lights work but I'm not getting any power going into the plug coil when I crank it over. I don't know what that carburetor controller relay is or what it does, the place that the link goes to for buying it doesn't even have a clue. Their description of the part is "We have no idea how this thing works but some scooters need them and we have them." I'm trying to start a new job after labor day so I'm desperate to have this thing running by the end of tomorrow |

50cc is cursed

Rust in the gas tank was the culprit. My Puma Cycles Romeo is up and running like new again after ditching the cleaned out gas tank and going with a full tank swap.I noticed after sitting overnight that the fuel in the fuel filter had separated into a layer of brown at the bottom and clear at the top. Which let me know the gas tank cleaning I did before I ever put gas in it was not good enough to prevent rust from contaminating my gas. Too many rusty spots in the tank. I didn't mention testing for spark, gas flow, and compression because that's the first thing I did, as mentioned, very basic first steps and all seemed well. But if gas won't burn it won't burn, no matter how much flow and air lol

Hi guys. I finally made an account, as a fresh scooter owner this forum has been a life saver so far. But I've run into a problem that I can't seem to find a solid answer for.
I had a running 50cc that I've been driving to work, it's my only transportation. The body was TRASHED when I bought it and I had to assemble it from a pile of parts. It ran perfectly for 3 months until I bought a new frame with a clean beautiful body and swapped my motor onto it. The motor ran for 5 seconds after the swap and hasn't come back alive since.
What I've tried to fix it:
-cleaned gas tank
-changed oil (motor sticker specifies 15w 40)
-new spark plug
-new spark plug wire
-new carburetor
-new fuel pump
-swapped starter solenoid
-swapped starter motor
-tried battery AND Kickstart, same result
-tried all old components AND new components with 3 different used GY6 motors and they all respond and act the same. They'll fire up with a bit of starting fluid then die after about 1 to 2 seconds.
I'm starting to be convinced that my new frame and body is haunted by the husband of the widow I bought it from. If you have any ideas, please help. As I said, this is my only transportation and now it's dead.
