My ZX6R is running a little rough. It has a jet kit and full Yosh exhaust. I just cleaned the air filter element and changed the plugs (put the manufacturer recommended NGK CR9E back in... it had NGK CR8EK in it- a hotter, dual-tip plug- should I continue to use a hotter plug?). Now it's no better than before, and maybe a little worse. It splatters a bit when I open it up and there is a very noticable power loss (from a couple of weeks ago). May be running a little rich, but it's hard to say. I suspect it needs some carb tuning. What's the first step? I haven't done any adjusting, so carbs shouldn't be out of sync.
Also, when I start it in the morning and let it warm up it wants to die right after I get on it and stand it straight up (adjusting the choke doesn't seem to remedy this). Don't know if that means anything or not??? Anyone have any advice so I don't waste a lot of time and further screw things up? I've done a bit of mechanical work on cars in the past, but I'm relavtively new to bikes.
