all current high-performance designs have switched to fuel injection
Only a journalist would say something that wrong.

ALL multi cylinder engines have EFI
Not limited to high performance.

EFI was not fitted to high performance vehicles only, it was used for all the reasons I covered in the videos you don't watch.

By the way we own the motorcycle land speed record for Australia on lake Gairdner because you assuie mechanics are drunks LOL
We ?
No
They, not you.

Ultimately, both methods of fuel delivery have their applications, fans, and detractors. It’s unlikely we’ll see a resurgence of carburetors in the future, due to environmental concerns. Fuel injection is, at this point, smooth and capable of more accurate, affordable fueling than any other method of atomizing the fuel and air mixture that humans have developed to date. We’re able to make our bikes run cleaner without sacrificing much at all. Fuel injection is reliable, and hey — you don’t have to figure out how to use an enrichener!

Can you say antique?

Yeah well that was all made clear about 13 videos ago, that you don't watch.
You want to teach mechanics go start your own thread.

Well gosh, you have a shirt too
Wowe

You didnt drive or build the vehicle.
You can name drop all you like it doesn't get you out of the carby hole you dug yourself here.

And none of you have been able to beat his old slower speed. Hell he has wrecked faster then any of your boys have ever gone.

Last week he did 378mph in Bolivia on their salt flats with a blown intake coasting through the clocks.

394mph FIM official top speed.

The current world record is 376 once one averages run speeds

Our data has showed 401.2 but its not official.

Last year we lost Sam wheeler the co driver when he wrecked around 200 in his streamliner.

Nothing to do with the topic.
Go and fap about your rickety heaps in your own thread and see who cares.

Re the last 2 videos cover the details of what a condenser does in points ignition system and next one Ill be covering the tune scope patterns that show it operating.

It was and still remains one of the least understood parts of an engine.

This video covers the exact view of the majority of mechanics in my time on what a condenser does.

At 21:38 in the video

Watch at YouTube

?t=1298

Which is, "I don't know what it does and don't think I need to know I just replace it"

Which didn't make much sense to me back then because, how do you know when to replace if you don't know how it works, and in fact it is easily understood and you can actually see it working in a tume scope pattern, which Ill cover as well.

The common explanation for a condenser (capacitor) is to minimize the sparking across the points as they open. That notion fails to include what happens when the points close.

The condenser, along with the coil inductance, is a resonant circuit. When the points open, the magnetic field of the primary of the coil resonates with the help of the condenser. Like striking a bell or plucking a guitar string. It makes the spark last longer giving better ignition. That can be seen on a scope connected to monitor the ignition. Remove the capacitor and see those oscillations disappear.

Very well put.

I would also add when changing points eyeball the gap to a credit card thickness, don't waste time with feeler gages, and get the dwell meter on it asap for correct gap.
The spark lasting longer
Is also similar to using premium fuel which burns a little longer/slower letting the explosion push the piston a little longer, reducing pinging and knocking.

Condenser is one of those things where the answer to what it does isn't mutually exclusive
Dampens spark over points and increase low speed energy.

Causes some confusion because if you say it does one of those things that would be correct, so many explain one of the things it does only,
but it does more than one thing.

Like 2 stroke expansion chambers Ill be covering later that do many things but are nearly always explained as doing 1 or 2 things only and leaving out the rest they either don't know or are not sure about.

To explain how one works covering only one aspect of it would be correct, but it leaves a lot of important other information out.

But a condenser is easier considering you can see it working or not on a tune scope, anyone who could use one would be able to see how it works on the scope.

A lot of tune scopes gathered a lot of dust in many workshops.
Majority of mechanics loathed anything electrical or electronic and you could get away with it back then but now its mandatory.

Mechanics only spoke of volts, only time they mention amps was starter and alternator and could tell you how many amps each supplied or draws.
Ask them how many volts are at the coil they can tell you right away, ask how many amps flow across a set of points and they'd have to think about it and try to remember ohms law to add it up.
Only have volts in our workshop, we don't need no stinkin amps.

It was trade school, they just didn't teach it.
It was explained like "Here is the battery and its connected to things the auto electricians deal with, so lets talk about engines" and that was it for electrical lessons for mechanics in the 1970's.

Pinging and knocking is the result of early or pre-ignition. Higher octane fuel has a higher flash point so it is less likely to ignite due to adiabatic heating (when you compress a gas, it gets hotter) and also allows operation in higher compression engines.

I would question the "using premium fuel which burns a little longer/slower".

In short it provides more spark energy but its only needed for low speed operation.

The field only has to collapse faster then a certain rate to produce full energy out which the condenser helps it do at lower speeds particularly cranking. See long span of total oscillating decay on scope at low speed.
At higher speed to total decay time is fast enough to reach full coil energy.

Hence a condenser that is not out of spec enough to burn the points can still slow decay and result is poor starting due to low coil energy at cranking RPM.

As it worsens it then gets to a point it will be out of spec enough to cause the point to burn.
