At the bottom of the tubes the width diminishes greatly. With a little finesse, a 1/4" suction hose can makes it's way to the bottom. I attach the suction hose to a long wood dowel with wire ties to gain enough control to get into the little inside diameter.

A long wood dowel from the hardware store with an eye screwed into the end of it will accept a clean rag for cleaning the grindings out of the tubes, much like cleaning the barrel of a rifle. Go easy on the very bottom if you get the rag in there. I sense it's a might fragile on the extreme bottom with valves & seals and other wee gee gaws down there.

Know that this forks on the bike method is messy, and a pile of rags at hand to wipe the suction tube off at each draw is a must. Oil on the ground isn't out of the question either if a nice lawn or blacktop is part of the location.

Forgive me the obvious, but an equal on each side refill is mission critical. Measure the oil level before drawing out the old oil and replenish to a similar level. I do believe the manuals state a replacement quantity of oil far different than reality.

Many here have favored Progressive brand front springs as a replacement to the stock springs. They seem to dive less and handle better. I think Fasteddysports should have them and he is good about getting them to you in a timely manner. He will answer emails and PMs sent from this site if you have any questions regarding price and availability.

One of these is handy too, and will pay for itself when you consider what a dealer would be charging for a fork oil change.

One other thing - the top caps are very very soft aluminum. I dinged mine up using an (shame shame) adjustable wrench. (at least it wasn't pliers... ;-)) if you need a socket that big, the auto parts chains should sell them for a few bucks, although they would probably require a 1/2" drive to twist them.

Overall this is simple job, and I bet you'll have no problems.
