Weird sound when running...ideas?

TheCollin · 03-26-2008, 10:03 AM

96 CBR 600 f3, It only makes this sound sometimes. It kind of goes away when I adjust the idle or the choke, and goes away almost completely while the throttle is engaged. It's a metallic vibration sound from the front right. I've gotten a few people say it could be an exhaust spring, and another said maybe lifters? I know it may be hard to give me an idea without hearing but anything is appreciated.

It goes down when I adjust the idle. It gets louder with more throttle. After riding a bit, I turn it off, IF i try to start it again withing 10 minutes or so, It struggles to start. In the mornings, I have to almost fully choke it to get it started, why? Also, after about 20-30 minutes of riding, I can feel quite a bit of heat from the motor, is this normal?

On the poor starting try checking the plugs/changing them or it could be the carbs might req. cleaning or adjusting ie. balancing.
Hope thats brought some idea's for you.

Plugs are brand new iridiums. I'm thinking about trying the seafoam for the carbs.Thanks
