Every ‘cross-point” screw on every Japanese designed motorcycle from the 1950s right up to the newest bikes in the showroom today were manufactured with a unique JIS screw head design we don’t see on products made here in North America. JIS stands for Japanese Industrial Standard.

You can never go wrong with OEM Honda parts. Fit, function, and reliability are never an issue. If you have a show bike, authenticity requirements dictate that you stick with Honda parts wherever possible. Of course, if show judges are looking at things like your timing belts, then you have bigger problems!
The following chart lists reasonable substitutes that have performed well for me and many others. This information is available elsewhere, but I decided to post it here for convenience since I’m often asked. Prices are considerably less than the equivalent Honda parts.

Coils are fabulously simple devices that work reliably and can last for decades with virtually no maintenance. I like to think of them as electricity “amplifiers.” When the breaker points open, the magnetic field produced by the primary windings collapses. Through the magic of induction, this collapse creates an energy force within the secondary windings of the coil. Since the number of windings is much greater on the secondary side, nominal battery voltage (roughly 12V) is multiplied to an incredible 8,000+ volts! This energy immediately finds a path to ground via the spark plugs…arcing helpfully in the process. Voila – we have ignition!

Emulsion tubes are perforated nozzles designed to pre-mix fuel and air for subsequent metering by the main fuel jets. Sometimes these are also called:
Honda GL1000 float bowl drain screws will be difficult to loosen for periodic maintenance if the float bowls are installed onto the wrong carbs.
There are specific left/right carb bowls plus a special bowl for carb #1 (with vacuum hose barb). The bowls will bolt up and run fine on the wrong carbs, but it will be hard to get a screwdriver blade onto the drain screws when the carbs are installed on the bike.
