Good news indeed Alan!!

Did they get the 10W/30 part correct too? , , or was that something the PO might've used?

In the time I've owned the bike I've put in about a cup of 5W40 oil - I have no idea what the previous owner used so I guess the estimate of 10W30 is valid! I used Rotella T5 5W40 when I changed the oil - couldn't find any 10W40 locally!

I rebuilt the master clutch cylinder on my 95 Goldwing SE however it continued to lose clutch fluid. My mechanic found that the slave cylinder was leaking fluid into the clutch and needed to be replaced...which I did. No more problems. Hope this helps.

BTW ...I 've never heard that one could use ordinary emgine oil for clutch fluid. I've always used DOT Brake fluid.

Who said they used engine oil?

Yup - use DOT4 brake fluid for the clutch. The concern was that the fluid was leaking past the seal into the engine, contaminating the engine oil. Oil analysis by Blackstone Labs, along with my crude experiment, confirmed that the seal was NOT leaking.

Alan, how many miles on the bike when this occurred?

The bike had 68,8xx miles on it when I noticed the lack of fluid. Since I flushed and filled it, and got the oil analysis results back I've put over 100 miles on it with no loss of fluid.
