Default Carb Setting Question

When setting up my carb and doing the spark plug tests, does the bike have to be ridden under load or can I just lift the rear wheel for testing?

Where I live it would be hard to find straightaways long enough to ride it.

Honestly at the time when I had been doing testing.. I did just that.... block it right against a wall, jack it up so it wont flop off under motion....
(Under load is the best as this is what itll need during the ride....)
Carry on... Itll at least get you a bit closer to what you want/need...

Default Don't lift it, put it on a stand.......

Under load is how you test your adjustments, not how you make them. Remember the dirt riders' motto "Ride it, break it, fix it, repeat". Set the bottom of the frame on a stand that won't move or fall, be it a bench, pallet, box, whatever's strong. Never try spinning the rear wheel with one hand on the throttle and one hand holding up the machine, that's a disaster waiting to happen. And you ought to see the 3" x 4" section of metal downspout that I caved in thinking just a little throttle before the centrifugal clutch grabs would be okay. It happens suddenly when there's no weight on the machine, and can feel like it jumped into the next county when that grab happens, no catching it. Adjust, ride, readjust, ride some more, etc. Concentrate on the fun part, that you get to ride. Repeatedly.

Under load. Do the plug chops while actually riding.
I have attempted some tuning in the garage. I burned up a band brake holding the brake while applying the throttle to “load” the engine.
There are two types of people. Those who can extrapolate from incomplete data
