One thing I noticed was the O2 sensor - you have to be very careful not to touch anything but the nut and the wire, or oils in your fingers could contaminate it. Also, only an Anti-Seize paste (or a specific O2 sensor lubricant should be used on the threads.
Peking,
Should have thought of that. I did wipe the soot off the O2 sensor and probably with my fingers too. I know it is always best to wipe off halogen bulbs or tubes for amps so the oil doesn't create hot spots that can damage them. Did not consider that. I did not use anti-seize either. You got me wondering if I should pull the mid-pipe and clean it and put it back with anti-seize. It would not take long to do. Can you clean the sensor with IPA? The anti-seize also probably makes sense. The sensor is on top with the backshell facing up, and SS will rust too. I did not use teflon tape either and wonder if I should to keep moisture out of the threads. I bet those sensors are $100.
Again I am wondering if the Autotune and K&N is really needed. Putting on the K&N is likely going to lean it further where you would need the tuner then. I will put the K&N in and see how it is, and you could tweak some setting richer to compensate, but there are so many that would be total hit or miss and likely to mess up the map. The K&N can be taken back out. I have a friend who is a professional welder. My welding sucks and I would likely ruin the nice mid-pipe. I am also wondering if the right way to do that is to drill a hole next to the existing sensor enlargening as I go until the wideband sensor bung fits in there, and then take it to my friend to do a proper job, and just cap off the stock O2 with the supplied plug.
I studied the tuner directions and do not think it would take any time to install that part. The real time will come from the computer learning, downloading, uploading, and repeating that iteratively.

I also expected it. Even on my quick ride, and coupled with this Forum I took too reading and studying some (big help) about peoples experience with the exhaust mods and the gains achieved. The CB1100 makes a nice platform for mods. Sure it is not bad stock. But, for the unheard of price for the full Delkevic and the surprising quality, it is really hard to beat. That CF pipe is hardly retro, but on the black/chrome scheme, it really looks good. The Delkevic system is an incredible value. The gains achieved are unusually high. Most slip ons or even full systems don't generally result in much more than 3-4% hp gains, with manufacturers gains to be taken skeptically. To get what feels like 15% is unusual, and the quality of the kit is very high. Not unusual to pay $3-400 for just a can.
It really wasn't that much pain. What was painful was taking the exhaust off before it was even registered, and then getting consumed in work while the best weather zipped by.

I love the V-twins as much as the inline fours, having had a Hawk GT, RC51, SV1000S, and TLR1000, and even a VTR250. A whole bunch of vertical twins too. I love the baritone sound. The VTR is underrated. The is a lot of value there and fun/cost ratio. I think the look is timeless too with great lines you don't tire of looking at. For a 17 yo bike, only the old style single large trapezoid headlight lens looks dated. The suspension is not the best, and I don't love the rearsets, but it is a terrific all around street sport.

One more reply to your reply. I pretty much knew what I was getting. If you consider I got the bike that really looked cherry, had already $700 in usable mods, and for only $5700, that left money in the budget for improvements. The previous owner clearly took impeccable care of it.
This will probably spin people up, and perhaps mistakenly lead people to believe I might have been thinking I was getting something I wasn't. I knew what this bike was and who it targeted. I had a GS1000e that had a ton of mods it reminds me of, only the CB is just worlds way better and modern/retro. But in this day and considering what Honda can do with a 1000cc inline four, getting 75-80 hp out of it is kind of pathetic (let the gasps begin), "tuned for torque" and all. Clearly Honda did not set out to cannibalize their CBR with this. It was meant to honor the heralded 750, and to appeal to nostalgic geezers (more gasps). BTW, I am one of them and part of the target. But for not that much money, adding another 10-15 hp and another boost to the torque turns this machine into a real sleeper.
Cue up all the responses that I bought the wrong bike....
I don't think so. I sold the VFR because it was simply too much. I am of the opinion that 160-180 hp is too much for the street in that weight class. But 100 hp and around 70 lb-ft is like Goldilocks.
