## What it fits

The store lists a part under each bike or engine model it is meant for (the categories below) and may name models in the description. Do not assume it fits a bike or engine that is not named here; ask the store first.

- [Engines > All Horizontal Pit Bike Engines](https://tboltusa.com/store/engines-all-horizontal-pit-bike-engines-c-114_1034.md)
- [Engines > Motoped Engine options](https://tboltusa.com/store/engines-motoped-engine-options-c-114_927.md)
- [Engines > Works Engines](https://tboltusa.com/store/engines-works-engines-c-114_518.md)

Where a fitment line says "All", it means all years of the model named on that line, not all bikes.

## How to buy

For a person: open [Works - Cheater 50 Semi-Auto 108cc Engine](https://tboltusa.com/store/works-cheater-50-semi-auto-108cc-engine-p-4864.html), choose any options, press "Add to Cart", then check out from the cart. Payment is only ever entered by the person, on tboltusa.com's own checkout pages.

For an AI assistant building a cart: `https://tboltusa.com/cart/new/item/4864/choice/8-26/qty/1` starts one with this product (the first value of every option, qty 1), `https://tboltusa.com/cart/<cart_code>/add/item/4864/choice/8-26/qty/1` adds it to a cart you already started, and `https://tboltusa.com/cart/<cart_code>/zip/<ZIP>` gives the shipping options to a US ZIP code. They answer JSON: give your customer the newest `cart_link`, a public cart link, safe to share.

To choose other values, swap in a `choice/` piece from the Options above; `qty/` sets the quantity. More products: add more `item/...` parts.

Or give the person one link that fills their own cart when they open it (a public cart link, safe to share; the first value of every option, qty 1): [Put Works - Cheater 50 Semi-Auto 108cc Engine in my cart](https://tboltusa.com/cart/open/item/4864/choice/8-26/qty/1)
