02 cbr f4i trouble please help
I just bought a setup f4i from a friend but it's havin some trouble and I was looking for some help from people on here. It's idle is jumping and when I pull te throttle there is no response until suddenly it gets the rpm up real high and if I keep them up it's ok until it goes to idle and starts o bog again. If I get a response with people who want to help I will take a video so you can hear it. Let me k ow what you guys think. Thanks

Well I have no gauges or anything so I don't have that light but I tested the plugs and when I started to give it throttle the spark flickered but it didn't cut out all the way. Maybe I should just replace the plugs?? It sounds almost like it can't get enough fuel but maybe it's the spark I'm really not sure

Can you borrow a set from someone? That's honestly your best bet. But if that's not the issue. Changing the spark plugs wouldn't hurt. Every time I buy a new bike I change the oil, coolant, plugs, air filter and sometimes brake fluid. But other than plugs I don't see that making much of a difference. Is the fuel pump priming (buzzing sound)when you turn the key on, before you start the engine?
Remember in order for a motor to run it needs 5 things
Fuel
Fuel pressure
Spark
Compression
And power(battery or alternator)
I know, it's alot easier said than done.

That sounds like alot more than just new plugs. Unless you have the worst plugs ever. Possibly your TPS (throttle position sensor) or something with your fuel pump.

Is this your first bike? Is the fuel pump priming? (buzzing before you start the motor). If not, you can also test the fuel pump by hooking it up to the battery and if it buzzes then it's good. For the fuel lines it's pretty much just a visual inspection. No kinks, weird bends etc.

Yeah it's my first bike and the pump is working when I turn the bike on I'm going to try the seafoam first then try to adjust the throttle sensor?

Do you have a service manual? If not buy one. I've had one for every bike I've ever had. Best investment money can buy for your bike. You can get them on eBay for under 30 bucks. Defenetly worth every penny!
