If you can't/wont take the MSF course, then the following will work
You know that the clutch is the left handle-lever (not sure what the exact term to use would be here).
Make sure you are wearing ALL of your protective gear.
Keep your feet on ground through this entire exercize.
Start the bike, in a safe location (empty parking lot).
Grab lever.
Put bike in first, let idle, do not touch throttle.
Slowly let clutch out, and feel when it starts to grab, and then pull it again.
Repeat this until you know by heart where that point is.
Now, start to let out a bit more, etc.
You can see how this is progressing.
After you know where the clutch intially grabs, you can apply a bit of throttle, and let the clutch out slowly, so that you begin to move at a slow pace. Then stop, and start going again.
Do this until you are ENTIRELY comfortable with what you are doing.
Stop there, go to bed, sleep on it.
Practice the next day, you MUST have complete control over the throttle/clutch in order to safely ride a bike. You CANNOT be too good at it.
The bike wont fall over while it is moving, due to the gyroscopic force of the rear wheel.
Just remember a few things. Slow is good. Don't put your feet on the pegs, as you only want to be traveling at a VERY SLOW pace, just enough to get the full range of the clutch, and then stopping the bike again, and repeating.
The rest of the gears are easy to deal with, as you don't have to up the throttle in order to go from first to second, etc. Nor do you have to have the same level of control over the clutch in order to from first to second, and so on.
Whatever you do, do not let the clutch out slowly, nor open the throttle up any more than is needed to get the bike moving slowly (we are talking maybe 2k, depending on your bike, you may need more, may need less).
IF during any of this, you have problems, grab clutch, squeeze break, and come to a full stop, then put the bike in neutral, and think about what happened, and what you should do to prevent that problem.
THINK BEFORE YOU ACT!!
PLEASE TAKE THE MSF COURSE
