yeah, you can do it yourself if you have a few tools.. Its pretty simple. But be sure to check the timing belt, make sure it isn't cracking or missing teeth. I would certainly suggest a chilton manual for it, if you dont know for sure what you are doing. You can bend / smash valves working on the timing belt of a honda if you do it just exactly wrong. a $16.00 chilton is cheap insurance.
If it did jump time, you should also look into finding out WHY it jumped time. Teeth missing on the timing belt is usually the case, but if a rock or a screw or bolt or something got loose inside the timing cover, that would cause it too. Could also be the cam binding. That would be BAAAAD. Be sure to figure out why. That way you arent adjusting the belt every weekend.
