Doing a pre summer tear down, maintenance and what not. had the bike since last summer,

Anyway. measured the forks before removing so I can install in same position.

Forks were off by 1mm. Left fork 31mm right fork 30mm from cap to tree. So opened the book to figure out where it's supposed to be and it says stock fork height is 10mm.

So I plan on returning forks to stock height but I guess my question is what type of difference in handling should I expect by lowering the tubes by 20mm. From what I understand small changes such as 5mm can drastically change how the bike handles. I just want to go into first test ride semi prepared if what to expect

If the effect it to make the forks longer, i.e. the distance from the axle to the handlebars longer, then you are increasing the rake and trail, which will make the bike somewhat more stable but less responsive. The opposite occurs if that distance is shorter.

Usually raising the forks is done for folks with ducks disease. Wot Wintr said, but it is hard to notice a 1/4 inch change. And you would be going back to stock height which should be a good thing. Changing the fork oil type and or weight, and the air pressure would be more noticeable.
