FZ07 running like crap.

Recommended Posts

I took the FZ07 out for a quick run today. The bike starts and idles fine but is way down on power. The bike won't pull past 6k in any gear. The gas is only a couple of weeks old. Not sure to start on troubleshooting. I'm looking for suggestions.
 
Thanks!

I read a thread once where a guy was having a similar issue. Turned out a mouse made a nest in his air filter. I'd start there and make sure there isn't anything restricting air flow. How long did you ride that tank of gas before you noticed a change?

I burned up MAYBE 1/4 of a tank before I parked it.  It was acting stupid as soon as I fired it up today.

Is it too early for a spark plug to start failing? Should the computer be throwing a code if it's missing?

That's what I thought. No light on the cluster. It seems to rev past 6k in neutral.

Well, where lawn equipment is concerned, some plugs test fine on the bench, but fail under load. You said it started going away at higher RPM. That's what "sparked" my post. They're not particularly easy to get at, but I doubt they cost an awful lot. I hate to just throw parts at a problem, but if they're cheap enough, and there are no other ideas, might as well.

I would echo checking the airbox. I've heard reports of lots of folks finding critters' nests packed in there, especially during the colder months or when the bike has been sitting a while.
 
Apart from that, double check the connectors for your injectors and maybe try topping off the tank with some fresh gas if there's room.

If it is a critter nest you could cover the snorkel or hole with a piece of fine wire mesh. When I took off my snorkel and replaced my filter I chopped off and used that mesh and secured it under the plate. Works great!

Do you have a fuel tuner or is everything stock? Does it feel like it's running on one cylinder?

My bet is on lack of air. It's the season where critters make nests and store food. First thing I did was make a mash screen for the FZ07 but I forgot to do the ATV. Sure enough it ran like crap and they make a nest.

Really good idea. I might do this.

When I've had similar problems in the past with cars I checked for loose spark plug wires, batt. elec. connections (the simplest things first) and that often proved to be the culprit. It's so new I wouldn't think it's anything major. I doubt any water was in your gas to begin with and doubt any condensation built up since you first put it away but it wouldn't hurt to siphon off/add fresh gas. Then again, it could be a critter thing as mentioned or something else. Good luck with it and let us know what was causing the problem after you've found it. Have a better new year!

Long story short it was the work of mice. The filter was jam packed with bird seed. My wife keeps a bag of it in the garage. I'll have to put that in some kind off container with a secure lid. I am having trouble finding a replacement air filter locally. Hopefully I remember where everything goes :)

Bird seed! I knew it! ;)
 
Im not laughing at your misfortune, but "jam packed with bird seed" is a good one.
