hey guys i was hoping somebody could tell me wat might be the wrong with my 05 zx10. when you start the bike it idles rough, spit and sputers but when you get on the gas around 3k and up it runs fine *kinda like it wants to clear itself up*. i took the two plugs out in the middle and they look good, didnt look at the two on the outside. also disconect the battery and connectors to the injectors and plug them back in and still no change. any help anybody can share will be appreciated.

your bike is being Jake Shields lol..........On a serious note check your tune, also check for vacuum leaks, your tb's could be out of adjustment

Change the plug and see if that solves it. If not, take that coil stick and switch it with one that you know is working. If the problem follows to that cylinder chances are its a coil stick.

Man its almost always something simple ...Mine was idling rough ..Not the 2nd gen lope ..After that ..it was missing n shit ... I had the throttle bodies adjusted and she purrs now that shes warm..

I paid for my synch but ordered a motion pro tuner so next time i can do it myself .. I mostly did it cause i piggybacked the job to a valve clearance check.. I dont adjust valves yet.. this winter i will try it out .:badteeth:

The big Gray Connector?.....do you know what that connector does?....I may help to identify what that wire effects for others if you get a chance. I have a pic I can post around the throttle bodies if you like.

yes blue its the gray connector located on the top left side of the throttle bodies right by the no#1 stick coil. that connector controls the firing on all 4 cylinders. the problem i was having was no#1 cylinder wasnt firing like the rest of the 3 was, fixed that wire back and wolla she was back runnin good again.

hate to revive an old thread, but any pics of this, i am having the same problem, i check the resistance on the TPS and it was within spec, i checked the voltage and that was within spec, i pulled the 2 sticks in the middle and they looked to be firing, i could not tho on the other hand get the outside coils off, not sure how, this is my firsty kawi, any suggestions, i have pc3 dyno tuned took it off and it still ran like shit, partial throttle it breaks up but then you floor it and it runs like a raped ape...any suggestions ideas thanks guys.
