Hey all, my name is Chris and I’m from Bethany, Oklahoma. I want to start by saying Thank You to those that have contributed to this forum, I’ve already been able to find several answers to questions I’ve had.

Long story short, I bought a bike this weekend from a friend of my wife’s that someone else had already installed a chinese 2 stroke kit on. She said her husband rode it a few times before “it quit”.

I’m a handy guy and I enjoy a project, I’ve owned a couple of gy6 scooters and a few motorcycles over the years (Yamaha radian, Fz6, Honda vt750). I enjoy working on mechanical things and electronics are a bit of a hobby as well.

10 minutes after getting it home I had already determined that it was a wiring issue, everything was electrical taped together in a bundle and the magneto had come disconnected. A little bit of pre-mix in the tank and it fired right up.

Like the wiring a lot of things on the bike needed to be re-addressed. I took the opportunity of fixing the wire to run it all internally in the frame. I also shortened drive chain, re-centered the drive sprocket, sleeved the kill switch wires and touched up some scuffs on the engine case.

The bike needed a total detail so I went to work on that as well, also removing all the cheesy “Hawaiian” themed stickers.

After a new plug and some carb tuning she rips. Top speed (downhill) is 35mph by gps. Which honestly is WAY too fast for this platform. It’s a hoot to cruise around 20-25mph though.

Here are some pics of the finished product. I also designed and 3D printed a few items for the build including a 60mm filter adapter for the nt carb, a custom mount for the Cdi and a sprocket alignment tool.

I have done some Basic Programming in the past, but to use a 3D Printer, is it something that might not get used due to complex programming for both something called the slicer as well as some cad program? I know this is not mostly the jist of the post. I thought of getting one that uses the thread stuff and included ABS as one it supports. I want to use the 3D print not just for decoration. I have found epoxy and a Dremel, or metal and a Dremel my way so far when needed.

Welcome to the forum!
Excellent debut post and thanks for sharing the pic of your MB. Great job on your build.
That sprocket centering jig idea of yours would save a lot of builders some grief. Very similar concept to the commercially available plastic tool I bought to accurately centre the clutch disc when rebuilding my Citroen 2CV engine..

Welcome good work getting her back on the road and designing the printed parts. It's easy to get really involved in this hobby and I'd say that's a good thing.

I'm the Old guy, Indian22 also in Indian Territory, about 90 miles West of Bethany, Cordell. Have fun with this and post often sharing helps us all.

Luckily 3D printing doesn't require ANY programming if you'd rather not. Most of it is point and click. I used TinkerCAD which is a free online tool made by AutoDesk, it's a lot like legos for CAD, simple to learn and use. The slicer applications (like Cura) actually do all of the work generating g-code for you. Most popular 3D printers will have a profile of presets that you can use to get the slicer pre-configured (speeds and feeds).

I happen to be using a Kingroon KP3, its a relatively small and inexpensive printer. It won't quite generate the heat necessary for ABS but it'll print PETG which is also very strong. All of the prints for this build were actually done in PLA.

As for the sprocket alignment tool, this is my only experience with one of these kits, I have NO IDEA how consistent the stampings are and of course every bike is different as well. I have uploaded this design to Thingiverse along with the dimensions, anyone can freely download and print this if they'd like.
