Once your moving its easy. With you having a leccy foot its easier. 1st gear push with your feet and the starter and you should be off.
Changing up.. Let the revs increase put pressure on the lever then reduce the throttle. The gear should happily shift up.
Coming down. Right this gets tricky. What you have to do is slow the bike down and when the revs get low. And i mean low like 3000rpm again apply pressure to the leaver and eases off the gas and again it drops down one.
The key is the throttle and revs combo. You want the gear speed to equalise the right way. Going up is easy engine speed over wheel speed. Going down its the other way, you want the engine driving the box enough to load the gears but ultimately the rear wheel driving the situation so when you close the throttle the gear slips in smoothly.
You wont break any track records but its easy once you know and a bloody site better than walking.
I have ridden and driven everything with bad clutches. A range rover. Land rover, severak motorcycles but my high point was bringing a truck back from oxford to northampton. Fitters wouldn't believe me.
It will date me to any hgv people but anybody who could make a decent job of an ERF with a twin split can drive without a clutch.
