Surging is generally caused by a lean condition, which, if your ECU is stock with that pipe, your bike most certainly is.

Have you tried wrapping your pipe? I don't particularly like the wrapped look (sorry Galaxy) so I wrapped as little as possible - but it works and is only noticable when looking through the fairing hole by the kickstand. After a very hard run (albeit in quite cool ambient temperature) I could easily touch the wrapping.brianmdavis said:Robert,
Make sure you watch the lower left fairing below the kickstand for burning. It is very common in this spot. I had it with mine. Still trying to work out the issue. I'll need to space out the fairing at the back left side. Can't have the pipes touching the fairing, heat shielding or not. You need air to move by the pipes in all areas. Mine hesitates a bit at 3500 to 4500 RPM. After that, goes like gangbusters....
What do you think of that sound!
I just thought it was an outside possibility that since only one pipe is wrapped that cylinders exhaust scavenging would be slightly different from that of the other cyliner. I didn't know if the tuning between the cylinders could then be different enough to make the bike run poorly...Fox said:you shouldn't be satisfied with a surging bike... or a midrange hole. you can tune that out. throw a powercommander on that bike and tune it, or have someone else tune it.
oh, and wrapping the pipe won't cause surging, wrapping the pipe causes higher exhaust temps inside the pipes, which increases exhaust scavaging of the cylinders.
You've got that right! That is why I am so surprised that even after getting the full kit it looks like I will have to add a PC3. Oh well, the one good thing about the ECU that I have now is that it raises the rev limit by 1,000 rpm. From what I have read the PC3 doesn't yet do that for the 999.Fox said:interesting... you paid upwards of 3K i'm guessing for a full setup, and the ECU isn't working as it should? thats just terrible. Is there anyway to buy the exhaust by itself, and buy the filters and a PC3 (and some dyno time) seperately? I'm looking into a system for my bike, and i don't like the idea of overpaying for parts that don't work as they should.
