I hate to admit it, but I took my first lowside on my '03 Honda CBR600rr last week on cold tires. Terrible...
Anyways, it was a left side lowside at low speeds (~20 mph) when I was coming home from school at 1 AM. Minimal cosmetic damage was done. Left stock turn signal, stator cover, and left fairing took most of the hit (as did my wallet...$1000 fix). However, when I picked her up, started her back up, and drove away from the newly engraved asphalt that would forever document my f*ck up, I noticed instantly some "course" vibrations around 5k-7k that I have never felt before. The best way I can describe it is the engine seems to be "rougher" at these RPMs and instead of being a smooth acceleration vibration like they normally are, they are more "course" and "rough". I know vibrations on high rev bikes are normal. But these are not the normal ones I feel when accelerating.
I got the bike to a shop the next day to check out the bike and they said besides the cosmetic damage, nothing seems wrong with the bike. Wheels were undamaged, forks, frame, etc. I told them about the "course and rough" engine rev vibrations at 5k-7k and they said they didn't feel anything.
Now I have been driving this bike for the past 2 years as my primary transportation. Anyone who rides 3-5 times a day, 5 days a week knows that they know their own bikes very intimately. I am no exception. I know how she rides, what vibrations she has at what RPM's, what RPM she hits her powerband, etc. I know for a 100% fact that the "course" vibrations I am now feeling and the "rougher" engine rev are true and not something I am imagining.
I insisted to the shop that the rougher feel was real. Earlier, I told them I recently installed a White Brothers slip on and they told me the symptoms I am feeling is because I have yet to install a power commander on it.
Now, although I KNOW I need a power commander, I have had the slip on for over a month and I NEVER felt what I was feeling before the lowslide. Again, I ride my bike every day... so the day that I installed the slip on I would have noticed a difference in the ride if it was showing these symptoms. However, I did not. Not until the lowslide.
I agree that I need a power commander on my bike, but I am curious if anyone has felt or may know why these new "course and rough" acceleration vibrations are happening? Could something have gotten f*cked up after the low slide to cause the roughness I am feeling now? Could it be the CCT? Do valve alignments get funky after lowside slides? Are there some common things I should have checked after a lowslide? I'm assuming the shop looked at these things, but you can never be sure unless you physically ask them to check it.
Its seriously bugging the hell out of me because every time I drive now I feel this damn new symptom in the acceleration and I feel like something is definitely wrong. I appreciate all your guys feedback and help on this. Anyone whose been down before knows you just want your bike to be back to normal again!
