80% of the afterfire problem resolved

So, I synced my carbs today and it took care of a majority of my problems with afterfire. I am pretty sure it hadnt been synced since it was assembled. Had a tough time getting the plugs and hoses off and it was way out of sync. I think the rest of my problem is exhaust related. I noticed that my stock mufflers have 2 holes on the bottom that vent alot of exhaust. Is this normal? I also think I have a leak on the right side junction.

Those holes are to drain moisture. Yes, it is normal to get exhaust out of them.

 

There were a lot of bikes that had a pinhole where you are thinking about at the "Y". I've repaired it with JB Weld. It is on the backside and doesn't show anyway.
