Chain...grind the heads off of one link.Slide link out.
LOL, that sounds like a lot of work. Why don't you just use a chain breaking tool?
And you need the same tool to install the new master link anyway.
I do this every time I change the front sprocket which is more often than I change underwear
I keep a box full of master links on had at all times.
Front sprocket I use an impact gun to easily remove the nut.
putting it back on I use a torque wrench, put the bike in gear and put weight on the rear break.
Rear sprcket; first I put the bike into a wheel chalk to hold it straight up.
Impact gun again, remove the sprocket hub, turn it over on a towel and use the impact gun to remove those 5 nuts as well.
Torque wrench to reapply.
Don't forget to properly tighten the chain tension you would need to prop the rear wheel up with the rear stand.
FYI if you change your gearing (especially the rear sprocket) you will be changing the ride height of the rear and the geometry of the bike. This is the 1 drawback of the single-sided swingarm.
