2007 FZ1 stutters/misses between 2K and 3K- FIXED! It is cured!!!! I just got back from a test ride after replacing the coils and plugs. The power delivery through the lower range was as smooth as silk. I've got my bike back! I can't tell you how appreciative I am for all of your input...

Dumb question here, but how do you test the resistance on the coils?

2007 misses/sputter between 2K and 3K I just followed a great thread on another forum from a guy who had this exact same symptoms as me. The thread took place over several months, and I must say, it was a great read becasue he was painstaking in his approach to getting to the root of the issue...

Thanks!!! Great information. I am going to change out the coils first and then keep the sensors in mind.

Thanks!!! I really appreciate it. I am just going to replace all the coils.

Awesome! That really is what mine is doing. I am going to pull them and check them this weekend. Thanks!!

The mechanic has thrown up his hands. He has no clue as to what is wrong. Anyone have a match for the $200 I just put in the fire pit?

2007 FZ1 sputter misses at low RPM Just ran that by the mechanic. He is going to try and reset and see what that does. Also, in that last thread I saw something related to the drive. Maybe this is the missing piece of the puzzle. I had snapped a chain and ended up buying a chain with no...

I'm on it! Thanks!!

2007 FZ1 stumbles/misfires at low RPM No, I didn't spray the coils with water. I'll do that when I get it back. What exactly will occur when the coils are sprayed with water if the coil is bad? Thanks for help!!!

2007 FZ1 stumbles/hesitates at low RPM Thank you. I think we're getting there. Just the way it sounds when it is idling, that is what it sounds like, but after testing to make sure all of the headers were heating up has me confused. Would the header pipe still be heating up if the coil was bad...

2007 FZ1 stumbles/misses at low RPM It does sound pretty familiar. My little hesitation comes and goes. When it has been at its worst, it occurred at all RPM's, but mostly now on acceleration between 2K and 5K. I would try the throttle body sync at least to follow with the maintenance schedule...

Yes, I did check the air filter. That was one of the first things I did. Thanks. My next move is to get the throttle body sync done, and after that I will buy the new fuel line and try that.

2007 Misses/sputters a low RPM I checked to see if the headers heated up. They all did. I want to bite so bad on the kinked fuel line, but I was having this problem wll before chagning the plugs and having to lift the tank. It would be so easy to order the new line which is only $40...

Thanks!!! I will check the headers. That is a great idea!

2007 FZ1 misses/sputters at low rpm I checked the fuel line and it seemed in good shape. As far as I had to pull the tank up to change the plugs, it wasn't putting enough strain to kink the line. The line much shorter than the 18" noted in previos posts, and it had connectors on each end. I am...

2007 FZ1 misses/sputters between 2K & 3K I changed the plugs about 1000 miles ago. How do I check the headers? Also, I was asked at what temps the bike does this. I rode it last night and observed that it started acting up at 185 degress plus. It ran well up until then. It seems like the...

2007 FZ1 misses/sputters between 2K & 3K I will check the fuel line. I have had to lift the tank to change the plugs, so that definitely could be the issue. What would I be looking for in checking the headers?

Frustrated. I changed the plugs in the fall after the bike starting running really rough and missing. That helped quite a bit, but there still was a little hesitation at low idle, especially after the bike had been running over about 10 minutes or so. I added some Sea Foam yesterday, and...
