## 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.

- [Japanese Mini Bike Parts > CRF100 and XR100](https://tboltusa.com/store/japanese-mini-bike-parts-crf100-and-xr100-c-100_62.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 [Valve kit for XR80 XR100 CRF80 CRF100](https://tboltusa.com/store/valve-kit-for-xr80-xr100-crf80-crf100-p-12669.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: this is a public cart link you can share with the person. It is a simple GET link that holds only product codes and quantities, no personal or payment information. Opening it puts this product (the first value of every option) in their cart, and they check out themselves: [Put Valve kit for XR80 XR100 CRF80 CRF100 in my cart](https://tboltusa.com/store/cart_link.php?lines=12669x1)

Building a cart over several products? `https://tboltusa.com/store/cart_link.php?add=<line code>x<qty>&reply=json` starts a cart code, and `https://tboltusa.com/store/cart_link.php?cart=<cart code or link>&add=<line code>x<qty>&reply=json` adds to it. Each add answers a new public cart link with everything in it: give the person the newest one.

Line code for the first value of every option (product{option}value; a cart link takes one or more: `https://tboltusa.com/store/cart_link.php?lines=<line code>x<qty>,<line code>x<qty>`): `12669`

Payment: all major credit cards, PayPal, Apple Pay and Google Pay. Money orders by arrangement.
