Motorcycle Repair: Honda shadow 1986 vt700, honda shadow 1986, lean condition

Question
the bike has been sitting for the past 6 months little ruff getting started but its starting. problem know is its not idling. once up to about 2500rpms makes a noise like its not hitting right. when let off the throttle then try to bring the rpms back up it cuts off. got it running tried to take it out but it stalled does do some back fire. i'm thinking some how maybe water got into the gas or maybe just needs a tune up? any suggestions ?

Answer
Ok my friend u r experiencing what called a "lean" condition.  This means the engine is getting more air than gas.  Lean conditions cause exhaust bluing, exhaust backfire/popping, sporadic running and stalling.  Your carb(s) need a thorough cleaning for starters and will most likely b your main issue.  Tell me this:  Was it stored with fuel in the tank and was the petcock on or off?  Good luck and let me know!
