My bike will pull strongly below 3000 RPM if I twist the throttle back far enough, it just doesn't "inject" cleanly at very small throttle openings and with a light load. With very light (small) throttle openings and at a constant speed (I've performed this test in the first three gears) you can definitely hear the motor gurgling, that I am convinced is due to an excessively lean condition. This is annoying because when I ride around town I am not twisting the throttle back any further than I need to (and I am being easy because I am breaking it in), and you can feel and hear the leanness. However, if I just twist the throttle back and accelerate briskly it cleans-up and runs very well. But, this is an 1100cc motor, and (from my experience) you shouldn't have to twist the throttle back this far riding around town - besides, you're very quickly going way past the speed limit around town. I can ride my fuel-injected VFR800 around town all day and not experience the same "lean" sensation or torque drop-off. My VFR injects smoothly and evenly at all RPM levels, from idle up to red line. Additionally, when I do twist the throttle on the CB1100 and accelerate briskly and shift at about 3300 - 3400 RPM, I feel a definite torque drop when the RPM drops below 3000 when I engage the next gear. I expected a smooth and linear torque curve, not one that drops off below 3000 RPM. I am going to meet with my mechanic friend tonight and see what he says after a test ride (his personal commuter is a Yamaha FZ1000).
Again, I thank all of you for your feedback and I will update you soon.
The original post strongly suggested the motorcycle had serious problems. This most recent clarification indicates something quite different and more along the lines of a personal preference based on the bike not living up to certain expectations. I wonder why the original poster does not want to have a dyno run performed? It's been suggested several times. Instead, the approach seems to be to have a number of other people ride the bike and get still more "seat-of-the-pants" impressions, rather than get some hard facts.
The dealer cannot work with these kinds of vague comments.
My bike runs flawlessly and it's unmodified. There is no hint of any of the issues described by some of the other posts in this thread. I cannot do anything more than speculate on the OP's riding experience but perhaps it's been unduly influenced by the characteristics of a V4 engine, which is quite different from the I4 in the CB1100.
For the record, the above comments are not intended to assist anyone with an Internet solution; they are to vindicate the CB1100 as being a superb motorcycle. Whatever the issue that gave us this thread, it's an anomaly not in the least bit representative of the CB1100 I own, and I believe I speak for the vast majority of CB1100 owners when I say this.
