The previous owner of my kx85 2004 had lowered the mono shock how do I adjust it so the bike will sit higher

Could have I guess.

Which ever way it steps up, usually to the right,

Your bike has a mono shock. It does have adjustments but it is for ride stiffness not necessarily ride height. But adjusting the rear shock will lower and or raise the seat a small amount. But at the lowest setting the seat height is still 792mm or 31.2 inchs. You may find a shorter shock but it would have to be from a parts search to match.

You will have to take it to a suspension shop. You need special tools to disassemble and recharge mono shocks. I'm surprised your friend was able to get any oil out of it though, normally this requires disassembly. You might have a problem with the shock. Either way, take it to a suspension shop. They usually don't charge much for recharging them.

Hello, Most all motorcycles with Shocks have an Adjustment on the "Bottom" of the Shock which makes the Shock "Firmer or Softer". By making the Shock "Softer" (Lowering it) will Lower the Bike when you sit on it. Making it "Firmer" (raising it) will make it Higher. The Firmest/Tallest Position on the Shock is usually best for riding Two Adults so that the Weight doesn't let the Rear Fender drop onto the Rotating Rear Tire. You can also Measure the Length of your Shock (Measured from Center to Center of the Mounting Bolts) and go to your Local Motorcycle Salvage Yard and buy a Pair of Shocks that will be 1"-2" Shorter and Make Sure that they are from a Bike that is Similar in Weight and Size! (You don't want to put a set of 125cc Shocks on a 900cc bike) but Please check your Rear Fender Cleareance First and make sure that you can lower the bike this much!!! Most of the Motorcycles that I Lower, I Never go more than 2" unless I am Positive that I have the "Clearence"!!! Thanks Azharleybob

Right. If you spin this adjuster so that tension on the shock spring is reduced, the height of your bike will also be reduced (at the expense of having less suspension travel remaining, making it easier to bottom out because of less spring pre-load).

you could try a little bit smaller rear tire. cheaper than the shocks maybe

on the back mono shock, there is adjustment the raise it up a little bit. The front are usually a gsa type shock, and you can put air into some of them to raise the front.
