The Ferret's 63K is pretty remarkable given that he has had 2 motorcycles from which to choose throughout the time he's had the CB1100. Per the Forum Mileage spreadsheet, Haystack had 111,000+ on 1/1/2021. Not sure if that's correct, but I know he was racking up miles like crazy a few years ago.

update: Alprider mentioned in a post that he has 160,000 miles on his 2014. Haystack mentioned that he had 130,000 miles.

Was Alp rider in Kilometers since he was overseas?

I didnt realize we have a mileage spreadsheet.. I'm behind since I haven't been able to ride since I got hurt at the end of 2020 and have 3 other bikes but I will dedicate to racking up CB miles as soon as I'm back in the saddle

63k miles? Good Lord, Ferret, think of your resale value!

Wagon, the bike I picked up recently had sat for a year. It ran ok, maybe balked at starting the first couple of times, but I just went on a long ride, ran through that gas, put fresh fuel in it, and it's been running like a jewel since.

We can only get 10% ethanol gas here in CA, and I used to be concerned about it, putting Seafoam or Techron Powersports fuel juice in my bikes every few tanks. But, I got lazy and stopped doing that quite a while back, and haven't seen any difference in performance or fuel range.

Just purchased a 2104 CB1100. Waiting for delivery. First bike ever without a fuel petcock...leading to a couple questions. Always used non-ethanol fuel in past bikes (with carburetors)....recommended for the CB1100?
Bike has been sitting for a few months. Would like to replace the fuel in the tank with fresh. IS there a way to drain the tank?
Thanks

Seems some points have not yet been fully addressed:
- any standard fuel looses its octane rating over time, so if the engine needs 87 and you park her with 87 in the tank, the rating will eventually be too low for the engine and cause knocking,
- in your car you can hear knocking (which can destroy an engine), on a m/c you can hardly hear it, if at all,
- if you start with 95 or higher, the time to pass below 87 will of course be longer.

Back to your question. If you tank is (almost) full of old fuel, take a manual pump (cost 10$, pump it out, add e.g. 98 grade fuel - let's say a gallon or so - and start the engine. Ride 2-3 miles to make sure only the best stuff is in your injection system. Now you can fill up with whatever you care about.

Next winter - unless you ride through it - buy a fuel stabilizer, so you can simply forget about pumps, petcocks and octane.

If you don't know what to do with the fuel you pumped out, use it in your lawnmower, knocking is no factor in small displacement engines.

There’s a German member—itsme67—who was first to 100,000 miles by a long way. If he still has his CB1100 and is riding it as much he’d be nudging 200,000 miles by now.

Update: itsme67’s website is [url=https://motorrad-und-touren.de/]here and claims 259,014 kms (160,943 miles) on his CB1100.

Further update: Looks from the website that the CB1100 was written off after an accident in 2019. itsme67 is still riding.

Older fuel can be used in your car as it will get diluted in a bigger tank .

Here in Colorado, regular grade E-10 gasoline is 85 octane, not 87. My CB ran great on 85 even at 14.000’+ elevation. Zero pinging, zero noticeable power loss, zero issues, and gas mileage in the mid-60’s.

I remember that and thought it was weird, but my bike ran just fine on 85 too.

Knocking depends on how much power you actually pull. Knocking isn't ever an issue if all you pull is 30 HP at 2500 rpms. The Honda guidelines do have to take into account that somebody may run her at high rpms all/many a times.
The impact of elevation (or atmospheric pressure), this is compensated for by the injection system.

Great info....thanks all.
