Just got my 2002 KDX back from the dealership/shop. It was getting a front tube replaced, as I punctured it before winter. The problem is after I got it back I noticed at higher speeds the front end seems to shake up and down. Is it something I can adjust to smooth it out?

Check and make sure the bead is seated properly all the way around is the first thing that comes to mind.

If that doesn't work maybe the wheel is out of true or the rim has a dent in it.

It's pretty common for mechanics to bind up the forks when they put the front wheel back on, which could cause the symptoms you described.

Your service manual will show you how to do it right.

make sure your forks are in your triple trees evenly to each other, not too high, or not to low. forks set in the clamps incorrectly will cause the bike to cavitate. beyond that, check the quality of the installation. (bent or pinched tubes) lastly, if the forks were assembled improperly (allowing air bubbles in the oil) it will ride improperly also.

All these tips are good but also turn out the brass screw on the top of each shock in case air pressure has built during storage with the different temperatures you expierience. This will make them too hard and give you handling hassels.

Cheers.

What's the air pressure in the tire? Maybe they never let off the bead seat pressure.

40psi would be a tad bumpy! ;)

Nothing you can do yourself can't be done by a shop at greater cost and likely screw-up in the process.

KDXFreestyle, if you read the post properly, CC is asking the originator of the thread to check his tyre pressures as they could well be at 40psi which is about what is required for the tyre to bead up properly. I'd hope most/all of us would know not to run 40psi on a regular basis (20psi or thereabouts seems to be quite common amongst newbies for the first few minutes lol)
It happens plenty of times that whoever changed the tyre forgot to let the pressure down afterwards (or pump the brakes).

If the mechanic is a real sleeze, it's not improbable that he didn't install a new tube, but rather a used one. Maybe one that had had puncture sealant foam sprayed into it which usually winds up in a ball somewhere in the tube which would cause it to be unbalanced.
