Well there's your main problem.
At this stage you want to download a workshop manual for the bike and read the electrical / ignition / troubleshooting sections to work out why you have no spark.
Someone here might be able to post a link to a downloadable manual if you cant find one via Google.
that could explain why it doesn't start. But first, a short story...when I was much younger I had a long string of success buying cheap honda cb's, fixing them, having my fill of riding them, and selling them for twice what I paid. So someone put me on to a cheap XS750 and I figured the 650's are shit hot and it can't be much different than a honda, right? Only problem was once I got it running, the thing was just a horrible monstrosity to ride. Seriously, I have had ridiculous amounts of fun on anything from a 50cc childs dirt bike to a Buell xb12s, but this bike?...not fun. It weighed wayyy too much, slow, vibrated, terrible suspension, shaft drive jacking all over the place, plus the most hideous excuse for a motorcycle sound I had ever heard emanating from the exhaust pipe and it was ugly and stunk to boot. I immediately sold it for a loss just to get it out of my hair. Plenty of fun motorcycles in this world, this is not one of them.
OP - Personally I do agree that the XS750 is a terrible bike to start on though.. but you are 15 .. if you are learning and safe and do some respectible changes and ride to school on it.. girls will think you are a hero!
No spark can be many things!
The best thing I bought was plug checkers that light up when a spark is transmitted.. i stuck these on while testing.
The coils are terrible on the XS and there is a good chance the HT leads and perished. unscrew the plugs from the leads, nip a little HT lead off, no more than 5mm and re thread your plugs. This was the cause of no spark on mine as was poor gapping. All 3 of my plugs were incorrectly gapped. I woudl do this and then work back through the system.
Dont' forget to look for obvious issues like broken wires or a kill switch that is off, even the sidestand has a safety switch. And as has already been suggested, remove the points cover and make sure they are clean and gapped correctly.
At this point, if you dont already own one, you should invest in a multi meter for checking voltage and continuity. You can get one for around $15 and it will make diagnosing electrical issues much easier.
But then not much left original on yours, I see.
An xs750 triple running through the gears is music. At idle, it's shitty. A lot of unfiltered mechanical sounds.
Who keeps a stock exhaust anyway?
Shaft jacking has never been a huge issue. I've never ridden one hard with stock suspension, though.
Beat the shit out of one now but with better rear shocks.
