Shortening Cb125s front shocks?

So is it possible to shorten the front shocks on a Cb125s? I’ve got to rebuild the front shocks on my 78 Honda cb125s and figured I’d modify them while I’m in there. I watched a video where adding washers internally would shorten them. Never modified a motorcycle suspension before.
 
Shortening forks also decreases trail and reduces head angle. Might make steering quicker, but could induce head shake. Modify frame geometry with caution.
 
No particular reason
In that case, yes, you can shorten the forks by putting spacers under the damper rod on top of the topout spring. You can also put in heavier fork oil and lighter springs along with more or less oil. None of that will be any more useful than shortening the forks, but since you don't have a particular need then it probably won't matter one way or the other.
 
Im 165lbs and bottom out the NOS front external springs on my CL100 pretty easily, when going off road.

That is helpful, thanks.
