Sup fellas, first time on. I just bought a used 06 1000rr thats supposedly all stock and it looks like it. It's only got 2k miles on it but it sounds like it spark knocks under 3k rpm. wondering if anyone else has had this problem. thanks

Don't know if I would call it spark knock under 3000.

I know my bike is pure stock 04 but these things are geared so high that it definately lugs the engine until 25000rpm. Then it just wants to go.

You are using premium unleaded right?

Oh yes, lots of people have it. Mine pings like crazy up to about 4500 RPM when I open the throttle past ~30%. Many people think it's valvetrain or other mechanical noise, but I'm pretty sure it's detonation. For some reason the concept of vacuum advance has totally escaped Honda's engineers as the CBR's ECU doesn't pull back the ignition advance when the throttle is opened. This fact combined with the type of noise I'm hearing and when I hear it, point strongly to detonation as the cause.

I'm building a custom ignition timing controller, which I hope to get installed and tested within the next week or two. If pulling back the timing eliminates the noise, I'll know beyond a reasonable doubt what is happening inside my engine...

Thanks for the reply. I've never ridden a 1000 before this one so I didn't know if it was common or not. Other than that I love the bike.

why the cutsom job, just get the powercommander and ignition module

yes, i guess maybe i can be a jerk, but i am tired of reading the same questions and hearing the same would be experts give out wrong info.

I may end up going that route, but before I shell out $300 for the Power Commander module I want to verify that retarding the timing can stop the detonation without completely killing low end performance or causing excessive exhaust gas temps. If I can't find a satisfactory compromise, I'll just live with the factory timing and save the $$$ I would have wasted on the PC ignition module. For the cost of a few specialty IGBT's and misc. components I can make a test module for less than 1/10th the cost of the PC unit.

would a power commander fix or at least help the pinging if everything else was stock? I'm new to the fuel injection scene.

LOL a lot of ppl also tell me to get the power commander I was thinking about it but then I crashed cause a car turn in front of me. Broke my femur, tibia and totaled my bike.

I finally got my ignition module assembled and managed to tape it onto the bike for some quick tests. As luck would have it, retarding the ignition timing did ABSOLUTELY JACK SQUAT to eliminate this damn "ping" noise. So it looks like I'm eating my words big time after huffing and puffing about vacuum advance and Honda's ignition timing strategy. For short bursts I was retarding the ignition timing by 25 degrees and all it did was make my CBR1000RR accelerate like a moped.

So what's next? Who knows, I might take a closer look at the fuel injection system to see if that could be the source. Even if I can't make this noise go away, I have to find out what it is...

I'll say it again PCIIIw/ correct map. I'm not just saying it. I have an 06 Cbr1000RR, and yes I had the same problem.

PROBLEM RESOLVED WITH PCIII AND MAP!

Oh... I thought the Power Commander discussions above were regarding the ignition module add-on to the PCIII. Sorry...

What map are you using?
