It is Sunday. Any place that sells fork oil is closed. I installed some of those cheap NOS Suzuki K10 forks on my vespa and while doing so one of them tipped over and most of the oil spilled out.

Does anyone have experience with using motor oil instead? I know the manual for my 71 Honda CL125 says to use 10W30 in the forks. 60's Suzuki forks are just as primitive as the Honda ones so it should be fine right?

I've heard of using ATF, motor oil shouldn't be too different.

I just found a scan of a K10 manual online. It calls for 10W30 too.

Is there a stockpile of NOS Suzuki forks out there someplace?

The guy has about a thousand Not sure how many K10's were made but it seems crazy that he would have that many complete NOS fork sets laying around.

K10 forks

One of the guys on moped army was negotiating with him to buy them all thinking he had a few dozen. They agreed on $13 per unit and when the total came out to over 13K he about passed out.

That is bizarre...why would there be so many spare forks sitting around for a 45 year old bike that wasn't terribly popular in the first place? That must be the entire world's supply of forks for those things.
