You are a life saver. This is the only video I could find that show's how to wire my specific engine. For the life of me I could not find out where that second connection goes. The one that is coming out of the engine, right next to the stator. I'm guessing that is for a headlight without a battery. Again you helped me so much. I appreciate it brother. Thanks again.

@@frontlawnp7355 Wiring from scratch is easy if you know how lol.

I would get some nail polish from the dollar store, black red ylw green blue, or better yet buy a pack of assorted wire from amazon/ebay, still need some colored tape or nail polish though for the solid/strip combo identification, to make everything simple down the road when you need to trouble shoot.

Nice video, I saw the spark. This was very informative* thank you. All I had to do was watch this one time and I know what to do now. I get some of my education from KZbin so thanks lol I am about to order the semiauto version because I ordered a jocky shifter for it. I am making a 125cc 4 stroke 4spd cafe chopper bobber bicycle out of a micargi vancouver. I was debating on the 150cc version but meh it is manual and with a jocky shifter Idw to have to worry about the clutch bc then it'll technically be a suicide shifter instead of a jocky shifter so I'll be alright with the 125cc just with aftermarket carburetor, exhaust, sprocket, and throttle cable. And the 150cc manual is really like 20mph more for like 140 more bucks. I think 50-65 on a bicycle is prolly fast enough and 80 might be a little too fast. I thought about it tho but 125cc will be just fine because I am lazy but I like to shift too so the semiauto will allow me to be somewhat lazy and still get to shift. Plus I like that semiauto is N1234 and not 1N234 maybe that's my laziness speaking for me. Weird tho how the 150cc weighs 38lbs and the 125cc weighs 50lbs lol.

@@MiniBikeMike ok thanks

[@christophersnyder7002]

Will it hurt the charging system if you run it without being hooked to anything? Referring to the two yellow wires.

[@MiniBikeMike]

No, not at all.

[@ChrisfromKeyfarm]

Great video, thanks.

[@tommymcguire6014]

hello, is it possible to make a video about the 6pin connector( gear selector sensor)? from switching manual to semiauto engine(lifan,yx), i changed my manual engine to semi auto, and now the reading all wrong on the speedometer!, thank u in advance

[@MiniBikeMike]

That connector on these engines has 5 wires, one for each gear and neutral. It doesn’t have a speed sensor wire. The speedo is powered by a cable from the front tire, changing engines should not affect the speedo.

@@MiniBikeMike i switch from a 110cc manual (1N234) engine to a 125cc semi auto(N1234), my question is how to get the gears showed up right on my digital speedometer.. do i need to switch wires? what to do?.. i ain’t an expert like you.. i’ll be glad to paypal you for solving my problem( french mechanics are useless) thank u😉

Just posted a video that will hopefully help you.

I need a wiring harness like that where do I get it? Or do you want to sell one?

hi my friend my chinese motor has two same yellow wires for charging and lights but my bike has yellow and white wires how will i know which goes to white? its the same ?

[@MiniBikeMike]

Your engine has a different type of stator than the one in my video. Take one of the engine yellows and connect it to a ground source. The other yellow connects together with the yellow and white on bike.

Great afternoon! Mr. Mike, I'm new to your channel but love the content. I have a few questions for you, im doing a father and so, building just the frame and tires, and looking for motors with all everything in a box type of project. We have a warrior 350 2004 looking for something with about the some speed but easy to build, any suggestions on motors in a box complete kit lol... I'm trying to have it completed soon it been sitting for a while!

[@MiniBikeMike]

All the engines I use are like the one in this video, a Lifan 125. They’re not the fastest engine, but the most reliable. They’re available on Amazon.

[@domantasburbulys352]

Hi, where did you buoght this wire just for run? I made it by myself...

[@MiniBikeMike]

If you watch the video, the wiring harness was in the box with engine. If you don’t have a wiring harness, they are on Amazon for $15.

Hello, just got same engine. Came with a separate stator. Does engine already have stator installed?

[@MiniBikeMike]

It should have stator installed. Is there wiring coming out of engine?

[@anthonya3220]

@MiniBike Mike’s Garage yes, 1 set with plug and one set with 5 wires I believe are from stator. Of the 5 wires 2 are yellow. Do both yellows go to regulator for charging battery, lights etc. Rectifier has one yellow and one while.

[@MiniBikeMike]

@@anthonya3220 one yellow goes to ground. The other yellow ties together with the yellow and white in harness. It doesn’t matter which yellow of engine goes where.

I'm trying to use my stock wiring because I have a z50 clone and I'd like to make all the lights work. How do I make that work

[@MiniBikeMike]

I guess I’m not following. You have a Z50 clone and you’re just changing the engine? Was the old engine 12v? If so, the wiring should work as it did.

Were did you get all the things in the box

[@MiniBikeMike]

Did you watch the video? I mention within the first minute that the whole box and everything in it came from Amazon.

[@tigerstripemark6973]

I have exact same engine ,unbranded are they really lifan or something else?

[@MiniBikeMike]

I’m pretty sure they are unmarked Lifan’s.

[@therealakalaska9485]

how many volts are you supposed to get out of the red and black stator wire

[@MiniBikeMike]

I’m not really sure. I’ve measure the output from the lighting wires, but never the coil trigger wires. Next time we install a 12v engine, I’ll check.

[@charliek2462]

Whats the wires/part called coming out of the engine and can you replace them or do you have to get a new engine

[@MiniBikeMike]

Those are your stator wires. They are part of a plate that is behind the flywheel. They are replaceable, you can purchase an entire stator plate that bolts right into place. It’s a fairly easy swap. Pull the flywheel…..remove the two screws that hold the plate on…..install the new plate/wires and reinstall the flywheel.

[@seanpusmucans3571]

Hopefully the 3 wires used is same as on yx 160cc pitbike engine and will work for me , just want bike to run

[@MiniBikeMike]

I’ve not owned a YX160. Hopefully, this works for you.

[@dannymotovlogs4254]

Hey mike could you tell me what size bolts and thread they are for holding the engine to the stand? And do you sell those engine stands and for how much shipped? Thanks

[@MiniBikeMike]

Honda used M8x1.25 bolts. I believe the top bolt is 120mm long and the bottom is 115mm. 5/16” SAE bolts will work in a pinch, just a tad sloppy. At this time, I’m too busy working full time to build any more stands. Sorry.

[@dannymotovlogs4254]

@@MiniBikeMike that’s ok with the stand and thanks for the feedback. Also would those bolts than work on the Lifan 125 engines as well? Thanks

@@dannymotovlogs4254 Yes, the Lifan is an almost exact replica of the original Honda engine….just a bigger bore and stroke.

Hey Mike I am sure you've answered this but I can't seem to find where. Who do you buy your engines from? I'm looking at Amazon and T-Bolt and wondering if is it worth the extra to go through T-Bolt or is it really all the same? Thanks!!! Really enjoy the channel!
