## 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.

- [Pit Bikes > Pitster Pro Pit Bikes](https://tboltusa.com/store/pit-bikes-pitster-pro-pit-bikes-c-46_63.md)
- [Pit Bikes > Play Bikes](https://tboltusa.com/store/pit-bikes-play-bikes-c-46_614.md)

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

**IMPORTANT ENGINE STARTING INFORMATION**

- You may want to consider setting up the bike on a stand for a solid starting location at first until your confident
- Turn on Both Fuel and Choke
- DO NOT open the throttle (do NOT turn the throttle)
- Move the starter down until it gets stiffer, your looking for top dead center
- Let the starter come back up and give a full strong swift kick ALL the way thru
- REPEAT (If necessary)
- DO NOT KICK RAPIDLY
- When warm just do not use the choke

Flooded Engine:
IF your flooded , pull the plug, kick it over about 10 times WITH THE PLUG OUT
Put in a NEW PLUG

For ease of starting:
You may want to consider our TRC EZ START HIGH PERFORMANCE CDI
Part No. TRC-9745 (NOT FOR USE ON ZS190s)

One more thing:
At times it helps to just crack the throttle a *tiny* bit to let air in.
