Re: 1998 Virago 1100 - wouldn't idle - now hanging valve?

lol i think the mechanic is trying to make some money off you lol.. first of all back firing doesnt happen in the cylinder it happens in the air box, detonation happens in your cylinder, which is the fuel is igniting before its set ignition time, there are a few causes of that if its your problem. my guess would of been if it was sitting the carb are for sure clogged, u said he fixed that, but way over charged you for it. if its still having idleing problems, id say its not getting enough air if anything, to be honest i think you should have it estimated by another mechanic, these bikes are awesome no doubt
