Hey everyone what ups im new to the forums and im looking for a little help

About the bike

I picked up a 79 xs400 from someone off craigslist for 300$ because it wasn't running. The guy that had it before me bought it running brought it home and it died on him and sat in the garage for six months. I replaced the voltage rectifier on it, cleaned the carbs out really good and now she starts up usually second or third kick. The guy before me had modded the exhaust and the bike was backfiring so i enriched the fuel because it was running lean in the right cylinder and now she runs nice and clean. The only problem is she wont idle, it will hang around 2000 when i get to a light and then slowly drop to 1200 then die unless i give it gas. Any ideas whats wrong.

P.S. sorry bout the long post
