This is one I learned from a mag. During a race I would sometimes stall in a corner. I would still have momentum but not enough to turn the engine. Pull the compression release in, let out the clutch, and release the lever while rolling on the throttle. You can do this in first gear and start. I can even get the bike started on a small whoop. Warning. Don't pull the compression release in all the way or it valve could hit the piston, only a very very light pressure on the lever is required. If you practice it is a life saver in a moto or when you are tired on a long trail ride.
