This particular flyweight is made for 38cc 4-Stroke Friction Drive Bicycle engine kits. Unlike other flyweights, these flyweights are a breeze to install and have a better mount than standard-drive 4-stroke motors with external transmissions.
If your electronic components are fine, your motor starts, but it won't do anything but revv, you might need to replace that flyweight. With this flyweight, it's simple:
- Unbolt the two mounting bolts of the stock/current flyweight
- Slide the flyweight off and replace it with the new clutch flyweight
- Bolt the mounting bolts in place, and you're ready to ride
- 76mm external diamter
- Note: This flyweight will not work with motors that require the flyweight to be mounted to a shaft. This flyweight will only work on friction drive engines, like the 38cc Lock-n-Load engine kit

It's the right size for a 37cc some call it a 38cc. The material is not the best,as far as gripping in heat but it's the right product for my stock 37cc. Works just like new!
