Odd behavior during initial warm up on colder days
« on: December 04, 2019, 03:03:25 pm »
My new to me 2010 C14 is doing some odd things in the cooler temps (40's-50's).
Where I park at work I have to maneuver down sidewalks and between buildings and as such do a bit of slow going when I head home.

If I try to ride off right after startup the RPM's Jump notably just as I add the throttle off fully closed, then settles back down.
Also if I engage ECO mode during this same time it stalls.

If I wait and let it idle a few minutes before I try to ride, both throttle & ECO mode are normal.
If I dont wait, within a few minutes of maneuvering, both are normal again.
During warmer temps (60's and up) its normal all the time, though I have seen the ECO mode effect idle a bit during initial warm up before.

Normal C14 quirks or issue?

Sounds like the high idle warm up, and totally normal.

Yea, the base idle is a little higher than when warm, but its the notable jumps in RPM that I don't understand/seem odd.

When I first apply the throttle during this time the RPMs jump to about 2000-2500 RPM, like I have really opened the throttle, but I have barely moved it.
Then in a second or two its falls back down to say 1200-1500 RPM that kind of jives with the actual throttle opening.
It does this every time I apply the throttle from fully closed.

The stalling if I try to put it in ECO mode is odd too.

Check, and adjust your throttle cable free play, and make sure the grip on the bar is not sticking to the pod , or binding in any manner. Sounds like a cable bind issue...bike stored outside always, or inside/?  Miles on bike? (yours, vs. prior owner) : how many owners? been worked on ever? risers added/bar mods?

more info needed..... :-X

I always let my bike idle before I ride off first time starting each day;
part of my approach to getting the oil to flow well, before I use rpms.  YMMV

5000 miles on the bike by the single PO, 400 by me so far.
No mods, basic maintenance done by the dealer over the years.
Stored in a shed most of its life, currently outside/covered.

I did adjust the free play to remove most of the slack (there was a bit) the day I got the bike.
Nothing binding or rubbing.

how long has the fuel in the tank, sat,  and when you added fuel and began riding the bike, and then let it sit again the time table?

basically, you have not run thru 2 full fill's of the tank, with that mileage.... fill, ride, repeat..

the fuel in that '10, was turpentine, when you got it.. tank off, dump, refill is what I do to every bike I get for "service"

there is no option for being stinginess,   throw old fuel away, and go forwards.

let us know how this works out.

First thing in the AM I let it idle a bit as I get geared up and I do not notice this in the AM.

Its after work, where I have geared up already before I get to where my bike is and want to get going ASAP is when I found this.
I prefer not to idle the bike where I park it (which is not in a typical parking area).
I assume my near idle maneuvering between the buildings and down the sidewalks covers the warm up before I really rev the bike.

I dont know how old the original fuel was.
I did siphon off what I could and filled with 93 Ethanol free and added sea foam.
I also did an oil/filter change (though it was pretty clear).

I have filled it a few times now (not full empty, last bar/60 miles range).
It has not sat more than 1-2 days since I got it.
It did have a lumpy idle when cold when I first got it, by the 2nd fill it was pretty stable, very stable now.

sounds like it just needs to be ridden hard, for a couple hundred more miles... to use up that fuel... 5k miles on a '10 model, needs to be ridden... things really tend to become stable around 8-10K miles..

basically it's just getting broken in still....

Probably.
I know the lumpy idle "corrected" itself over the past few hundred miles.
I think I will run another tank with seafoam too.

Its definitely just a cold idle related thing, and does not last long.
Last evening when it was 64 degs, it didn't do it, but did the previous days when it was in the 40-50's.

I need to make it a point to mess with the throttle a little in the AM during that initial warm up when its in the 30-40's to see if it does it then.
Maybe something is gummy/stuck when that cold idle kicks in and a few more cycles can correct it.

I'm not a big proponent of Seafoam, in any way, for any of my bikes... the best solution is GOOD quality clean fuel, and at the most if there is any moisture in there, the addition of Iso-Heet (the red bottle). It is a great injector cleaner, and actually does bind up any water to be burned; but pouring in anything, and just letting it sit will NOT help at all.. the fuel must be used up, and burned, to alleviate any issues..   Oh, and don't combine additives in any single tank... use whatever, run all that fuel thru/out, and re-fill with new fuel before any changes in additives...
