Fork oil normally smell bad?

Got busy making dinner last night and just let it drain out overnight.  Woke up this morning and my entire house stinks to high hell.  Wifey might kill me since she’s home all day.

Not normally but some gear oils do and if someone used gear oil instead of actual fork oil. Gear oil can have a very strong almost a sulfur  type smell.

This isn’t gear oil smell, I’m one of the strange few who actually like the smell of 90W.  If I had to guess I’d bet on this being the OEM oil put in in 87.  I’m at work so I’ll try to get a description of what it smells like when I get home, but it’s nasty and strong.  Did a google search and apparently it’s common but haven’t come across why.

After many many years of dealing with OEM Japanese bikes going as far back as the 60's and including both Street, Dual Sport enduro's and even my MX bikes I have suspected that all of the Metric Manufactures including  Mom Yam used some form of fish oil for their suspention dampening needs, including fork oils, due to the horrid smell always associated with swapping in new oils.  Ironically my numerous encounters with the MK1's were some of the worst in odors when dealing with OEM original swaps. Combine that with the ink pen springs Mom Yam provided as a means of supporting the weight of the bike it is no wonder that my MK1's ALWAYS went to a whole new level of handling both on road and off road just by going Belray 12w for fork oil and dropping in a set of Progressives setup with 1" of preload and never ever needing any form of air above the oil to provide perfect riding for 100's of thousands of miles...  After emptying of that nasty OEM stuff and going with Belray I never experienced and form of odors...

Well the smell had dissipated over the day as I had the wifey open the garage door, but it still stank.  Got everything cleaned up and new “Blue” oil put in.  Hopefully gonna ride to work tomorrow so we’ll see how it all goes.
