Just a quick one i have just bought my first big bike yamaha xj600 bought it for a good price full service etc and owned by a lady and garaged for the last 5 years, hence why i went for this as i was used to a 125cc and thought not bad bike even tho considered an astra diesal van in the bike world!! but you gotta start some where?..the bike starts just fine but it is hunting does not have a nice balanced tick over plus lots of white smoke when you rev it up and it smells of fuel i.e smoke smells of fuel a bit, there is no creamyness in the oil and no leaks etc around the bike, there is a slight tapping as well, should i be very worried and would it be worth getting the carbs ballenced etc?..all help welcome!!
