New to me 1978 XS650 running rich. Let me start by saying i'm not technically savy (YET!) but my beast is running rich. Black spark plugs, backfiring, lost of power etc. After almost every ride, i clean out the spark plugs. The air/fuel screws are about 2 or 2.5 turns out of the recommended 1.5. Any recommendations? My next thought is the air filters. My bike is stock, which ones should i buy?
