First Post. Nothing to contribute.

Re: Detonation
Dude, this is a BRAND NEW bike. This is clearly unacceptable. Something is wrong, and you need to make the dealer figure it out and fix it.

Re: Detonation
Sounds like this one needs a gas analysis job done. Surely there is a shop within a reasonable driving distance that has the equipment. Ask around - club racers are a great source of such info.

I rode a friends CBR100RR back in late Oct. It took my friend and my brother to unfold me from the "ergos"...but WOW - what a rush!

The one I rode sounded like it has detonation, too. See if you can check out another RR....especially if the exhaust gas checks out ok on spec.

Re: Detonation
Absolutely, take it to the dealer and get your concerns documented. Keep taking it back until it's right, if you hole a piston you're going to want a mile long paper trail showing you had concerns while the bike is/was under the warranty period and you attempted to get them addressed.

Re: Detonation
This may seem obvious and you may have already done it but scour the web for something on this. There's gotta be a ton of forums and boads devoted to this bike. Those things can be a great source of info on quirky or unusual problems. That was my experience with a site for Suzukis and also Honda V4s.

Re: Detonation
Obviously, you should take it to the dealer and have it thoroughly checked. I also remember reading somewhere that the Hondas have an exhaust valve in the exhaust system (i.e. not the valve in the cylynder head) that can make a noise similar to this. You should be able to find something by web surfing.

Re: Detonation
Taking it to the dealer and documenting it, is a great first step. Put the reponsability on Honda's shoulder, not your pocketbook! In the meantime... you might wish to check-out products that contain "Duralt", which is often used for storing fuel for long periods of time, as this usually lowers detonation problems on certain motorcycles, cleans out some carbon deposits, and increases fuel octane slightly. You should be able to find info in the web on this product, including Some persons also swear by Marvel Mystery Oil, but I have no experience with this product on Motorcycles, nor do I know if the use of either of these products will void the warranty!

Re: Detonation
It's interesting to note that old British bike manuals and texts (eg Phil Irving's "Tuning for Speed") refer to the phenomenon as "pinking" which sounds a little better description than "pinging".

My solution to your problem? Rev it harder.

Re: Detonation
Put some toluene in it the gas... about 1/2 a liter for 5 gallons.
