Clutch problems?

[Dead Eye]

You shouldn't need to have the carbs balanced once you replace the downpipes - its not something I would do under the same circumstances

If it makes you feel any better, my bike is rough throughout the rev range and isn't smooth in any gear no matter what you bloody do. I've put alcohol and STP Fuel Cleaner down its throat, replaced the air filter, oil, oil filter, plugs, cleaned and balanced the carbs and the bugger still isn't smooth New engine time me thinks
