Q & A

What is the name of the business the speaker is starting?
-The name of the business the speaker is starting is 'Columbia Customs'.
What is the main focus of the video?
-The main focus of the video is rewiring a small Chinese quad, specifically by simplifying the wiring process and explaining the basic spark circuit.
Why did the speaker initially find wiring intimidating?
-The speaker initially found wiring intimidating because it was complex and required understanding of the connections, which they initially didn't want to deal with, opting to pay someone else to do it.
What are the essential components needed for the basic spark circuit?
-The essential components needed for the basic spark circuit are the CDI, connectors, spark coil, and the wires from the wiring harness, which can be recycled and color-coded.
What tools are necessary to put together the basic spark circuit?
-The necessary tools to put together the basic spark circuit include wire cutting pliers, heat shrink wrap, a soldering iron, and solder.
What is the purpose of the CDI in the wiring process?
-The CDI (Capacitor Discharge Ignition) is in control of the spark, managing the spark timing and providing the spark to the spark plug.
How does the speaker test for spark when there is no kickstart motor?
-The speaker tests for spark by attaching the spark plug to the coil, ensuring the plug touches a metal part of the engine head, and then turning the motor over to look for a spark at the plug gap.
What is the first thing the speaker suggests checking if there is no spark?
-If there is no spark, the speaker suggests first checking the spark plug, then working back to the CDI and eventually the engine.
What additional components does the speaker mention will be covered in future videos?
-The speaker mentions that future videos will cover building a kill switch, hooking up a possible key start, push button start, and setting up a charging system.
What is the speaker's plan for the 1984 250r two-stroke motor?
-The speaker plans to use the 1984 250r two-stroke motor in a cross cart project, combining it with a frame from a three-wheeled ATC, adding a roll cage, and modifying the exhaust.
How can viewers stay updated on the speaker's projects and business?
-Viewers can stay updated on the speaker's projects and business by following the official Instagram account mentioned in the video.
