Just had a great day at Haccadown. When taking some of the small jumps the bike tends to land nose first which can be disconcerting. Had a similar conversation with Geoff who experienced similar.
Tried a bit more rebound damping on the rear which did help a bit but in retrospect Im not sure it is the solution.
Any ideas on what I might be doing wrong? suspension? technique?.
Think you're supposed to give it a handful just as you take off. I could of course be talking bollox as I landed nose down every time but then I just go over these things and pray......

I think the idea is to lean back more (once in the air lol)?! I've tried it and it works for me....I did a short study session while at WWB. Of course, the person that will know the answer for deffinate is J. Squibb Think it has something to do with the wheels rotating etc??... and rear brakes (also when in the air )?! Think it only applies on the really big jumps though. Again, I too maybe talking complete bollox and wouldn' know for sure as I only get a few feet.
Just make sure your accelerating at the point the front wheel leaves the ramp and it'll hold you in the right position for a good landing. Backing off is a natural reaction but one that could hurt - nose dive!
If you power over the jump the back wheel will be forced upward, thus pushing the nose down, (scarey).
If you power down over the jump the back wheel will land first,(scarey)
So if you average out the speed & power in the run up and as you leave the jump you should land flat.
I guess you need to consider the size and angle of the jump and are you landing higher, lower or on a par with the take off.
Jamie's jumps are wierd, they look far to steep and i cant get me head around how much forward motion he gains.
In the past i have considered asking Jamie if he would do a jump school for us, not for free style jumps but more for control and skill over trail and MX conditions, what do you think??

I think you may have written that the wrong way around, accelerating as you take off results in a rear wheel landing which is good, decelerating on take off results in front wheel landing (not so good!) If the front goes too high a quick jab on the rear brake will bring the front down.

I'd be game for that. WWB was the first time I've got proper air on my bike and my confidence grew with each lap. That said I'm certainly no expert so some pointers wouldn't go a miss.
I've just been watchin' Red Bull X-Fighers from Battersy on DAVE channel, the moves those guys pull, WOW, that's impressive!!! Doubt I'll ever get to that standard?????
Like Geoff, I found the TRF evening at White way Barton a great introduction to Jumps. Was a bit ragged to start with but got better the morelaps I put in (still scary though)...lol I'd definatley be interested in some tuition from Jamie. Would love to know how he has the balls to do the FMX he does. Top bloke...Respect

Nah i think i'm right, if you keep the power on after the frontwheel has left the ground, the back wheel will keep pushing upwards and the front will come down first.
If the jump is something small, off a mound of earth about 1 or 2 foot high, I blip the throttle as the front wheel hits the mound and lean back slightly taking a neutral body position as the rear wheel leaves the ground. Usually, both wheels land at the same time.
With larger climbs, I power up the climb and concentrate on body position whilst maintaining a constant throttle position, leaning forward enough to keep the front wheel on the ground, but not so much as to make the bike nose dive if it gets some air off the summit.
I have no idea if this is what you should do, but it seems to work for me .

Nope, (as much as it pains me to agree with Dan) it's the exact opposite way.
It's just the same as when you apply more power to stop your front wheel dropping into a hole or gully. You have to initally carry the front wheel (with power) until the back has left the ramp or bump. From that point onwards your 'flying the bike'. The same rule applies here though - rev more to raise the front, brake to drop it.

As Rich says if you keep the power on after both wheels have left the ground then the front may come down. However I'm not in the habit of watching when my rear wheel takes off, I just accelerate up the ramp, or if its a drop off as I approach the drop. My Avatar shows it in action!
Whilst I don't claim to be able to put my money were my mouth is on this one, I know enough people who could, so here's my explanation, the jump angle is dictated by the take off area or ramp angle, keeping power positive on take off especially on four strokes means the bike will adopt the same angle, too much power will cause the front end to climb high which in the past was the chosen way to jump and land rear wheel first( see early Evil Knievel),
shutting down as you jump will cause a nose dive, once in the air the rider will normally check the rear brake once to level the bike then a second time to set the bike up for the landing, If you watch this Robbie Maddison jump at 1:00 in you will see the bike alter it's flight angle twice from the use of the rear brake,
if however the bike is over checked and coming in nose too low the throttled will be used to raise the front.
