It seemed a little better after I left it tied for a day,
Did you leave it tied out in the hot sun without food or water?
You need to give us a little more information, not the least of which:
1. Does your "neighbor" know what he/she is doing when it comes to bleeding brakes?
2. Is it just the front brakes that are "suishy" or do the rear brakes smell like fish as well? (Sorry, couldn't resist
3. Are your brake fluids at normal level? Any bubbles in the sight glass?
4. Is there any evidence of leakage anywhere in your system? Drips, puddles, etc?
The symptoms you describe sound like there's still air in the system that either has yet to work its way out, or more air is being induced when you apply the brakes.
In a little bit you'll be able to post in all sections of the forum, and we have several mechanical pro's with actual experience with your model (I confess, I have never owned a 650
)) and they will come rushing to your aid.
