For the most part my bike lives in the 45-60 mph zone, and a lot of that, even at 45 mph, is in 6 th gear (between 2500 and 3500 rpms). My normal shift point is around 3000-3200 rpms, and my bike has never been over 5000 rpms, and never anywhere near redline to "blow the crud out". (What a hokey wives tale) but there is no problem running this engine to redline, either occasionally, or all the time for that matter. Engines are designed to run within a certain range and the range on this bike is from 2500-8000 rpms. It's ok to run this bike in any gear between those rpms (although it is electronically rpm limited in certain gears meaning you will not be able to run it at 8000 rpms in certain gears) but other than that, it will not harm this motor to run it anywhere between those rpms and it's not " better" for it to run it at any given rpm than another rpm in that range, and the only "crud" you are going to blow out of a modern engine is the crud in your head.
This bike is designed to run on 87 octane and up to 10% ethanol, and running that will not harm your motor unless the bike sits for extended periods of time without some gas stabilizer in it. Running a higher octane is useless, and a waste of money, but will not harm the motor. Running pure gas will not harm your motor either. These bikes will run 100,000 miles whether you run 10% ethanol or pure gas, whether you run 87 octane or 93 octane.
This is not just my opinion, it's all right there in the manual Honda gives you for the treatment and care of your motorcycle.
Modern materials, EFI systems, 02 sensors, ECUs etc are all engineered to keep this motor running basically no matter how you treat it, but applying 1970s automotive wives tales, and back yard garage procedures to 2015 engines is a waste of time. Times have changed, and so has engineering, and materials, and what your uncle or the local hot rod enthusiast, thought he knew in 1970, just no longer applies to modern motors or motorcycles. Engineers have learned a lot in the last 50 years, and what they have learned has been passed onto and into your CB1100.
Coming up on 20,000 miles no issues.
And checking your signature leads me to the conclusion that you are a firm believer in that
