FI model - Need some help and information

bogdanb · May 11th, 2009, 12:48 PM

Hello, I bought my '08 recently. Almost an year old, mileage was 1300 km. I will try to describe my worries and concerns.
So.... It is a FI model...when the engine is running, I can hear a sound ( like a high frequency sound ). It gets stronger when you approach the dash board , or if you open the tank cap. Most probably it's from the fuel pump, I presume it is normally for the FI models. The only guy with Ninja 250 'R, I met in Sofia, was a new owner like me and he wasn't familiar with his bike.
So far , so good. The really annoying starts in warm weather, and while the tank is exposed to direct sunlight. A sound appears... somewhere from the tank cap. Don't know how to describe it ...it is like a "whistle", or like the previous sound, but much more stronger. If I open the tank cap , an air gets out and it stops...till the next warming.
Can anyone tell me is that typical for the model, or it is about a problem with my new , second hand bike.

Please, excuse my English, I am a foreigner, we even do not use the same alphabet around.

The carb. model does the same thing.Seems Kawasaki did a poor job of venting the tank.

Not a problem it's air replacing the fuel some times louder than others.

The gas tank noise is very common, think of it as your bike talking to you

I do

My FI model does it too - nothing to worry about - lots of threads about it on here and somewhere a mod to sort it if you find it irritating. I too like to think of it as my bike talking to me

Steve

Thank you guys... As I understand you Steve and Viper-Byte are FI model owners and you do hear the same , don't you ?

I mean ...this sound is really loud sometimes. It scared me, because I think that it might reflect to fuel injection pump problem.
