Default Sounds funny

My 01 Katana sounds like itís missing. I have replaced plugs and cleaned carburetors. What else could I be doing to make it stop this?

When you start it up from cold does one of the exhaust header pipes feel cooler than the others? It could be caused by a vacuum leak on one cylinder which would cause it to run funny. I was testing mine out and couldn't figure out why it was running so rough and then realized I hadn't plugged the vacuum line from the 4th carb into the petcock. (Yes, I know that would also cause fuel delivery issues) The rough running cleared right up when I plugged that hose and stopped the vacuum leak.

I wouldn't recommend trying to tell temperature by touch. They heat up super fast. Spray water and see which evaporates first/last, or use a laser temp gun. Should tell you which cylinder is acting up.

Haha well I do it right when I start the engine then use my ninja reflexes to not get burned. That being said, it is a great way to get burned so doing it your way is probably better.
