My kid has a 2014 KX85. The suspension has been revalved and sprung for his weight. It also has a lowering link on the rear that drops it 1.5". Sag is set to 85mm and it looks like the bike is sitting high in the front end. Currently the forks are raised 15mm from flush, stock is 18mm. I'm going to raise them some, but how far should I go with it? If stock is 18mm, should I raise them to 23mm?
When you lower the back you need to also lower the front to keep the geometry as close to OEM spec's as possible or the handling will suffer. When you lower the back it increases the rake of the front end and if not corrected the bike will corner poorly.

I know that sometimes they are used to lower the bike to match the rider, but that is a trade off. Anytime I have elected to use one I have first checked the front end rake with a guage and then after the install I change the for leg location in the clamps to attempt to get the rake back to the stock angle, but it is not always possible. In that case I would then reduce the rear sag a bit to help. That can also cause some other issues.
If yours was done for that reason, then work to get him back to riding stock height as soon as possible with the oem linkage.
