POOGS, but not POOGS?

I'm good at turning a wrench, but still not good at diagnosis of issues. So here it is:

The bike is exhibiting symptoms of POOGS, but the usual POOGS fixes are not working, i.e. cleaned the gas cap and the breather line. I really hadn't thought it was the cap since it came off a bike that had exhibited no symptoms of POOGS, but I cleaned it anyway.

Now one thing I've noticed with this bike vs. my bike: the fuel evaporative system. I had noticed this thing right away because of the two lines coming out of the tank, whereas my bike only has one vent tube. Could there be an issue with that thing? I think I have the one from the crashed parts bike. Should I look at swapping them out? Should I remove the system entirely? I mean, if my bike doesn't even have one and runs fine, couldn't I take this one off?

Recommendations/suggestions/questions are appreciated cuz I really want to get to the bottom of this.

the evap system, or recovery system is an emissions system that is not on all models. If you can somehow disable it for diagnostics, I would try that first.

I am sure you will get lots of feedback on this issue and the emissions systems on these bikes.

mine doesn't have the evap system, but if it were me, I would have already removed it as long as it were not required for state inspections.

just my opinion

the evap system could be at fault. try putting a vacuum cap on the extra nipples, and cap off the lines at the carbs (if there are any) and see what that does... if it still acts the same.. check into electrical issues.
