I know exactly where you are coming from. I'm 39 and just getting back into riding MX after an almost 10 year hiatus when the kids came along. Momma would no longer allow me to bolt out the door every Friday night/Saturday morning and be gone somewhere to ride/race until late Sunday night. I never sold the bike (92 CR500) and would fire it up and ride some trails for an hour or so every couple months but no MX from 93 until last year. Talked the wife into letting me get bikes for my 9 and 6 year old and we started riding together. Then I talked her into allowing me to upgrade my steed when I got an 01 CR250 (not enough gettyupango) and then my CRF. Now I'm back riding on the tracks and trying to get my speed/confidence back.
I was a local track, midpack B rider when I stopped. Man, have these guys gotten faster while I was gone. I think I'm close to being back to my former speed but have trouble finishing top 10 in the C class! Jumps are scary. Period. Because, at least for me, I'm thinking about all the bad things that could happen. But you know what? When I get the gumption to do a jump I haven't done before, 99 times out of a 100 when I do it, it feels easy. Then I wonder what had me spooked for so long.
Practice controlling the bike on takeoffs of jumps your comfortable with. Try to make it do different things. Jump front end high so you can practice brake tapping to bring it down. Jump front end low so you understand what "panic rev" means to pull it up. All these things will give you the skills you need to make corrections should the jump face ever throw you wrong. Now the only thing to worry about is correct speed to clear the jump without overjumping - that can be just as dangerous as coming up short. Find somebody doing the jump consistantly and follow them... get your pace off of them.
90% of it is mental. Once you clear a new jump, you will wonder what you were so scared of. Now, doing it consistantly with other riders all over the place is a whole different story! That's my biggest issue now. I would rather roll a jump because I don't know what the guy in front of me is going to do rather than try it and land on him, hurting both of us. But then I have to worry about the 15 year old on a 125 behind me doing it and landing on me!
Good luck and remember, the older I get, the faster I was.
