There are ongoing issues with 990 owners dealing with stopped up fuel filters, and I'm pretty certain that it's dissolved tanks from ethanol stopping up the filters.
Ahh...that makes sense as to why my bike went sputter sputter, cough cough. I'm going to also pull the injector and see what it's like.
No use replacing the filter and not checking that out as well.
