Haha okay so maybe that should be added to my to do list
Though the circled section doesn't look too good, either.

Your middle cylinder looks like there has been water in it. Plug isnt supposed to look like that. And your battery is NOT supposed to have 17 volts.

It has had water in it? Like through the carbs into the engine? Is it going to die? And it starts around 13 and then slowly goes goes up until it reaches around 16.6 when I plug my multimeter up to it

15V is about the maximum safe voltage. Looks like it might be time for a new regulator.

No. It would be unrelated.

Okay I should still get one anyways, I'll order one. What tests do I need to do for the starting issue? I'm thinking it just doesn't have enough power sometimes, like I just tried with a battery charger set on low and that boost helped it start right away....

Here's some videos
This is still with the 16 voltage battery

This is with a jumper just to show it does start and what it sounds like normally.

had the same issues with my XS 750 which was converted to your later transistor ignition.

1)check your battery voltage, if its under 12v you will not get proper spark.
2)thenI would check spark on all cylinders.
Do you have fat nice spark on all 3 cylinders?
3)if there is no spark on some of the cylinders I would cut a bit off the ignition cables (1cm) and then put them back into the spark ignition coil.
swap around ignition coils,check the plugs on the coils.

My issues were a combination of bad connections in the loom and a bad ignition box.
1 battery is has to many volts as I've been told...
2 I have spark, just not big and fat on 2 of them...
3  so you wanted me to cut 1cm off of the end under the tank? And then move the connections around, to test if one is bad?

Start by cutting off the end by the plug cap, they are usually worst. And replace that rusty apark plug..
