Just picked up a 94 Fat boy with 75,000 miles yes 75k. Runs well. Do not have any history on bike as far as what fluids were used where. The bike sits for a few weeks starts up quiet, no smoke and the tranny and clutch work excellent.
I am draining an ounce or two out of each and found one trick to determine if it is fossil or synthetic by putting the cup of fluid on ice and seeing if it gets thick. If it does it is fossil. Any other tricks?
Here is what I have done so far.
1. Primary removed 1.5 ozs of fluid. As far as smell goes it smells like true differential oil, like that from the rear of a 1970's car. Should I assume that it is fossil?
2. Engine oil has a pretty strong smell of gas so I am not sure if the ice trick will work.
So I guess the big questions are any tricks to determine if current fluids are synthetic or fossil, and what type and what weights I should reinstall. I also live in South Florida.
Thanks for the input.
