YZ400Fer69, If the engine does stall, do as 98YZ advised and either upshift and bump start it on the landing or just keep the clutch pulled in for a smooth landing(you could then try up shifting and bump starting while the bike is still rolling after you've landed with the clutch in ). The reaction is more like the rear of the bike lifts than the front dropping. So if you've given the bike enough gas to clear a gap or whatever, the worst senario will be a 'front wheel first' landing, and they're not really that bad. I actually like to land front wheel first on occasions, and if the bike is straight in the air, no problems. If the bike does get a bit sideways in the air, I actually prefer to land front wheel first. I doubt you'll have any major problems. Just start off with small stuff and progress from there.
