Changing Fork Oil only??

[DGK5]

I have a new to me K5 that has done 46000 klms .
I have been right over the Bike and also done a full service on the Bike.
About the only thing that I have not done is service the Front Forks.
Is it possible to leave the Forks on the Bike and just Drain the Old Fork Oil out, that's without removing the Forks ?.
The Forks are NOT Leaking and seem to be working ok
but after 46000 k the existing Fork Oil must be pretty shitty by now and really needs replacing I would think
PLEASE advise what you think about just changing the Oil only if that is possible  ??
thanks for your help

Unfortunately the fork have to be removed to drain the oil out.  Plus you should slosh a bit of cleaner around the inside which can't be done on the bike (unless you are incredibly strong).

As mgt says, you have to remove the fork legs to change the fork oil, there is no drain plug

Have always wanted to create a drain in forks. Drill, tap n plug. Worked fine in the old bikes. Might look into a spare set to experiment.

Certainly worth doing, I did mine at 54k the oil was rancid and the top bush really worn.

It takes about twenty mins to lift the front on two axle stands & drop the forks out, it's hardly an all day task without drain screws.

I always drop the yokes out too & check, regrease the bearings. Suzuki didn't grease them properly & the bottom one always goes rusty. So it's worth doing while you're at it.
