I purchased a used (1700 mi) 2006 F4i back in March from a reputable Honda shop. At roughly 2500 mi I picked up a lite RPM dependant vibration. I am at 3000 mi and the vibration has gotten worse. I can feel it in the tank, pegs, bars, etc. It gets worse at higher RPM's and the bike feels slightly down on power. However, the vibration is inconsistent from ride to ride. It never goes away, but will get worse or better.

I consulted with the GM of the shop, who is also a friend, and he said to check the torque on the frame bolts and header bolts, as well as change the oil. I have done both of these with no change in the vibration. Last week the battery quit taking a charge so it has a new battery as well.

I also recently noticed that when I am at an idle, and I apply the brakes, the vibration gets slightly worse!

Any suggestions? Does this sound like valves out of adjustment or possibly an ignition or stator problem? I am lost.

 

Frame bolts=motor mount bolts?? I'd check those out.

 

I have almost the exact same problem - I took it to the shop on Tuesday to have them take a look. I will reply to this thread with their outcome.

Yes, I am referring to the motor mount bolts. I checked the torque and they were good.

 

The solution is to learn to live with it [:@]

All f4i's buzz and vibrate, usually after a prolonged ride my hands and feet are buzzing. its just how these bikes are.

You can get bigger bar ends to help with the clipon's vibration.

 

BoRKa: Your response is similar to what I have read. However, with this being my first street bike I am not sure what is an acceptable amount of buzzing.All I have to compare it to is how the bike was 500 miles ago. I would expect a buzz if it had 10,000+ miles on it. Three fellow riders have road the bike and two thought it was fine, the other didn't. It was smooth as glass, the exhaust notewas smooth,with only a slight buzz in the bars. I simply don't want to keep riding it and do significant damage.

kiker14: Please let me know what you find out with your F4i. (What year is yours and how many miles?)

 

Hey, I'm going to call the dealership today for an update - It's an '06 with approx 2,700 miles. Stay tuned...

 

Kiker14 - Any word on your ride?

 

Is it stock or does it have an after market exhaust or anything? That could possibly introduce vibrations.

My vibration problems went away when I got my PCIII working properly

 

It is bone stock.
