1981 GS550t Fork oil replacement

[Demio0892]

Hi everyone, Im looking forward to changing the oil in my forks on my cafe racer, however I have a question: Does my gs have drain bolts in the forks or do I need to remove each fork leg and open them up to drain the oil ? If so what oil weight should I use ? Thanks.

The small screw near the bottom of the fork is the drain. 10 weight fork oil is good.

But please keep a few things in mind.
1. If you just open the drain hole, you won't get all the dirty oil and crud out.
2. You WILL have to open the top of the forks to put new oil in.
3. Only remove one fork cap at a time, unless you have a jack under the engine.
4. The proper way to add the proper amount of oil is to have the spring out and the fork held vertical and fully compressed. If you can't raise the back of the bike off the ground to get the forks straight up and down, it's easier to remove the forks from the bike.
5. Especially if you remove the forks from the bike, plan on replacing fork seals, too. Just because "they weren't leaking" is no excuse. They may have not been leaking because everything was already gone from the forks. Replace the seals NOW, do the job ONCE.
