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.

Hey Yz400fer69,

Did you happen to buy a pair of goggles from a guy in KY? :)

I have to agree with therapture. When I rode 2-strokes, I found myself using this technique more often. For me panic revs and rear taps have always been a natural reaction to the position of the bike. Not something I thought about. I think a lot of guys do it for show, but that's another issue. It comes down to two things. Body position and keeping your weight low and centered on the bike. If this is done right, it's very easy to position the bike correctly in the air. Really, as mentioned above, the compression braking naturally points the bike down for you when you release the throttle. I just don't find the need to ever use the rear brake anymore since converting to 4-strokes. Now it's more an issue of getting the front end up if I'm coming up short or want to land rear tire first.

can't be on and off the pipe on a big-four, unlike a 2-stroke. Just not the same on the ground and in the air.

I'm getting a lot better at getting the attitude (front/back wheel) right. Just when I think I've got it I do an endo or something.

A pro once told me that if you have the correct technique when approaching and leaving the face of the jump, there is no need for all of this brake tapping stuff. He said the supercross tracks and jumps are the exception to the rule because you are driving off of the face of the jump until you leave the ground.

He said that on outdoor jumps, unless you are really fast, most of us don't drive all of the way off of the jump face. We usually let off just prior to lifting off and let momentum carry us over the jump.
