Turning off
« on: August 21, 2019, 07:31:22 pm »
Hmm.  My Concours has started acting up on me a bit.  When I cold start it, it runs a bit rough and then wants to turn off.  Sometimes I make it down the driveway and then it shuts off on me.... or my fav, turning from the driveway on a sharp right and then apply power and bam, it is now, or was already off (I am very careful there now).  Has been doing it several weeks now.  After it comes off the cold idle onto the warm idle, it can't quite stay running until a few min later when it is actually warm.

In the past, I would check my logs and realize it had been a year since I ran Techron through it and run a tank through and it would be fine again for another year.  That didn't work this time (just did that at 39,965mi, 1800 miles/3 months ago).  Not sure what to think.  Correct gas.  Great mileage.   No power delivery problems after the initial 5 min.  I wouldn't expect such an issue on a modern, fuel-injected 4.  Any thoughts?  Run another tank of Techron?

Yes, I am way overdue for a valve check (never done yet), but I don't think that is it.

So is that air filter still in your Amazon cart or did you finally install it?

Could be a bad batch of gas.  What's the warm idle speed?  Could be water in the gas...  Could be a lot of things.

I bought it.  Waiting to install it with some other stuff.... if I can ever get my mechanic friend motivated.  But I don't see how it could be an air filter.  As those get dirty, I believe it would affect top RPM speed first.  And it certainly wouldn't suddenly get clean when the bike is warmer :)

Has been more than one tank.

I think about 800rpm?  Cold seems to be something like 1100.  Are those even externally adjustable?  I seem to remember looking for an adjuster and couldn't find one.  Even if it is just a stop gap, it might be worth messing with.

Hmm, I will investigate.

I know :(  That is why I am a bit concerned.  It isn't a major problem, but it is annoying.

800 rpm is too low.
I had stalling problems when my idle speed was set at oem spec. Since I set it up to 1300 it has never stalled again.

  • It's only really cold if you fall down in it.

Yes, it is externally adjustable. In fact, Kawasaki ran a cable down the left side of the bike and put a knob on the end of that cable so it is easy to adjust. Look around the drain tubes in front of the left peg, just inside the mid fairing panel and you will find that cable. Adjust the idle so it is ~ 1,100 RPM when up to temp; the high- speed idle when the bike is cold is not adjustable (well, not easily and it is not made to be adjustable) so it will simply idle at some speed greater than the mechanical idle is set.

In major maintenance inspections at 25K and 50K miles the only thing I found changed significantly was the throttle body synchronization. The mechanical linkage between the two T.B. banks, 1&2 and 3&4 wears a bit and so the two groups of two T.B.'s get slightly out of synch. This hurts both idle and off- idle initial acceleration at low throttle openings. Otherwise, there was nothing that  needed to be changed on my bike even at 50K miles.

come on Max... 40k miles... no valve inspect.. and air filter still in package waiting for that elusive valve interval...

It's time man... get'r done dude.. don't be the poster child for "it ran great right up till she blowed up..."

I just replaced my fuel filter in a "pre-emptive" wise mode, as I figured if I didn't, I'd have issues "on the road".. and didn't want to do the job on a picnic table at a rest area.. wise move.. it looked horrible.. never really had any "running issues", so it was just a worthwhile thing, to ease my mind.. valve inspect, and air filter... need regular (at least by now one look...) attention.

YMMV.. as it appears.. Techron is great stuff, but changing a fuel filter is cheaper, in the long run... and lets that Techron get to where it needs to get...

Is it behind the panel?  If so, that might be why I remember it but didn't find it.  I would check now, but it is raining AGAIN.

Yeah, I am wondering about TB sync, too.  Definitely on the list....

I know, I am so bad.  I have never removed the gas tank before (even with all the farkling over the years) and I am very leery to do it without my friend helping.  Otherwise I would have at least replaced the air filter, coolant, and dumped the gas tank on my own.  Really, the ONLY reason this stuff has not been done is because of him not being available and my not trusting the dealer to do it right.  I wanted to do it all at the same time (I have quite a list now- all that plus leaky cam seal, valve adjust, TB sync, header bolts, windshield lube, inspection of stuff).  I will start actively pestering him again.... I think he is much more "stable" now.

now you make me feel guilty, because I moved back to Ohio from Va.....

heck, I would have just said "bring it over" if I still lived there.. I'm guilty of "neglecting" my bikes, over time, especially here in OHIO where i get a half year out of my License plate sticker.. but man o Man... just pick up some tools, do a stiff shot of liquor, and "go mess with it"... slow, careful, pay attention to what you remove, and it all works out in the end... of course saying a prayer won't hurt either....

take charge, and be large.... I see this long list of farkles, and think... wassup/?



so, time to do some work, and be full of pride....  I know you love the bike....




you know I'm just being ridiculously silly, knowing how long we both been here..

My idle is lower cold and goes up after warmup.
Some of the simple maint. stuff can be fun Maxtog.

Max, don't make me ride my Indian down there and show you how it's done...  Although I've never done maintenance to a Gen 2 bike.  But hey, it's not my bike and I'd love to experiment on yours.  I do have a 'rebuilt' pump with a new screen in it.  Not sure if a Gen 1 pump will work in a Gen 2, though.  Update, that pump is used throughout all model years.

Why would you need to remove the tank to replace the air filter and coolant? Is that necessary on Gen2s? Not so on the superior Gen1s.    :)
