I Have a shimmy in front fork when I hit a bump, what do you think

SOURCE: Can you straighten torqued front forks on a 2002 Yamaha TTR 125 L

you should be able to saporrt bike so front wheel is off the ground   then take a marker and put lines around where the forks meet the triple trees that hold them in place their should be some allen head bolts that u can loosen on front of the triple clamps  once these are loose you should be able  to move the forks back to strait again in line with the handle bars just line the lines up that u put on them earlier and tighten the allen bolts back up    also  when making the lines  make them from left  to right so marker is touching both fork tube and triple clamp   this is only so you get can keep them the same ride hight as before 

SOURCE: Handle bars shake up and down at 50-55mph

Could be a few things I would recomend checking all the head bearings really good, it also could be a busted cord in the front tire. When this happens it usually causes a vibration at higher speeds

Front wheel needs balance,and also the rear wheel may need to be centered. If someone replaced the brakes or tires and the rear wheel is off center to the front that will cause the shimmy.

I had this problem with my 01 and my 07 all I needed to do was change the tires. We looked at everything else that it could be and once I changed them we saw the problem. They were cupped really bad. Only shimmied at about 40mph if I let go of the bars.
