Hello All,
This is my first post and first project within the motorized bicycle realm. I originally came across another post on here that gave me the inspiration for this project. Credit goes to @Chobiker for the original idea and successful execution of adapting a 30 series torque converter to a 49cc 4 stroke engine.
Here's the current iteration of my 49cc motorcycle project I've been working on for the past couple years. Originally it was a bicycle with pedals but I've mounted an engine, attached a custom rear sprocket, custom front wheel with a disk brake, and new paint job.
The bike ran great for a while however the clutch started having issues. I decided to convert the transmission to a belt driven setup which enables me to start from a stop without over stressing the engine. The transmission kit I used was not designed for my engine so I had to machine my own mounting holes and weld a custom shaft to mount the pulleys to. The result is a much more reliable system and a lesser top speed of 20 mph.
The single front brake is sketchy at best so I'm glad I have a low top speed; a rear brake is definitely next. I want to ride it around how it currently is for a while; I mean, the engine isn't even broken in yet. After upgrading the brakes, I'd like to look into upgrading the carburetor. I'd likely want guidance on that when the time comes.
