Some gear/seat problems...

So I recently bought a 1997 GF HooKooEKoo...it works great and I absolutely love it. However, the gears and seat (or seat post, rather) have problems on occasion. The issue with the gears is this: sometimes when I shift out of 2nd, I seem unable to pedal at the desired speed. It feels like the chain just comes off or something, but they are on. And the seat post, which I like to have in a fairly high position, goes down when I do moderately intense trails/jumps. Any suggestions? Can a basic tune-up fix these problems? Sorry I don't know too much about bike lingo and stuff, so if my problems don't make sense, my bad haha.

you might want to try a different seatpost clamp, some just don't do a very good job and will cause you seatpost to slip.

you shifting troubles could be due to old/stretched out cables or it could just be that you derailleur is out of adjustment. check out park's repair section http://parktool.com/repair/byregion.asp?catid=53.

First of all, I hope you aren't shifting under load - meaning, are you pedaling hard when you shift?

Second of all, the seat clamp if it is quick release should have a tension adjustment knob on the opposite side of the lever.

Third, it might be better to ride with your saddle lower than you would when riding on the street or for XC if you are doing jumps. Don't want to hurt your jewels.

You might try describing your shifting related problem again...almost makes me think you have a freehub starting to fail, except it only happens when shifting from the second largest cog?

Is the seatpost clamp tight? Is it a quick release or bolt type? More info on what you've got and what you've done about it so far might help...
