"Premium" is a bit of false labeling, as it is more accurate to say higher octane fuels are less volatile, making them harder to ignite. When fuels are easier to ignite they can create detonation, which means the flame front goes supersonic (exploding) rather than progressing uniformly until the fuel is consumed.

So a hotter plug may help and using a lower octane fuel as a way to get ignition makes sense. You'd just not want to do it all the time or you'll get detonation when under load. I'm sure these bikes have knock sensors intended to mitigate detonation but it's still not something to do intentionally.

Maybe the 890 has Multidisplacement system, like the HEMI...in cold start….

Crack the throttle slightly when you hit the starter button and you won't have a problem. When the bike starts it will idle fine. Weird glitch I expect but doing that I have no issue.. I started doing that when strangely enough last summer I switched to 15-50 oil and the bike would not idle at start up without stalling. Issue started the day after I changed the oil. Next oil change went back to recommended 10-50 and bike idled just fine at start up ever since. Don't ask me because I still can't believe the oil was an issue.

Interesting about the oil.

I'm going to try that trick next time.

Overall the 890 is a real winner. Has some minor quirks, but nothing to temp me away from it.

Planning to take it up to PA to do the BDR-X next month. I think it's going to be even better than the 690 on that ride.

Much as I'd like to join, the V85 is on street tires and now that I've done a bit of gravel and easy dirt they are not what I'd want on the BDR, even though they could handle most of it with no problem

Understood. I feel the same way about taking the SAS on it. It definitely could handle it with no real issue, beyond street tires puncture way too easily. Not worth the potential headache.

Hopefully you and I can get together sometime before it gets too cold to be fun.

Humanity will be fine. The HD is back where it belongs, the 890 is back in it's rightful place in the garage, god is in his heaven, and I need not experiment any further with a Pan Amaerica. Some borrowed bikes are returned with good feelings and lasting positive memories, other bikes generate relief that they are returned. I'll put the Pan America in that last category. Not a bad bike, but nothing inspirational either.

The ride home on my fully service, 1 year old 890 was wonderful. It remains a pleasure to own and there is no thought of anything else being able to fill that specific niche in my riding life. I only put a little over 6K miles on it over the year. Not a lot, but better than any other dirt bike I've owned. It's truly a great bike and I have no regrets.

Be careful it may not want to leave. They are famous for key fob issues. Wouldn't wish one of those on my worst enemy although in all fairness 1 in 5 seems to be somewhat trouble free.

All in your perspective. The HD owning dealership guy who handled me the keys yesterday told me how great it looked. He was there again today when I brought it back. As I went through my discoveries of what made it so odd, he smiled and said, yep, it's a Harley.

Awesome! I'm extremely pleased with mine, too. Can't claim anywhere near those miles, but glad to hear you still feel that way.

I'm glad to hear the 890s are holding up. It's Swedish sister threw me a CEL at 40 miles for a knock sensor, but resolved itself and hasn't come back on just yet (245 miles ODO).

The good news is my 390 Adventure so far has been problem free (2k miles), so I figure I'll always have at least one running KTM to ride! :D
