Elevation above sea level is 930 meters.
Grade of gasoline is either 87 Octane or 91 Octane (at the time of the issue surfacing I had put in 91 Octane. But having used 91 actively over the past 12k miles, I am not sure if this could be the issue).
I think we're at about 5% ethanol blended for the 87 Octane. Do you suggest I do only 91 Octane for a while?
I will check readings from the throttle sensor first and see whether it is within the factory set tolerance limits. Then I will do as you say tomorrow and check if there's a change in performance. I understand that the green reference mark tells me what the existing position is, is that right?
I would expect fuel efficiency to go down by making the mixture richer. Would that be correct?
Invader, thank you for helping me out. I am keen on understanding this bike more and more, and I hope to start home-servicing of this wonderful machine once I get out of warranty (few months).
I also looked up this post of yours for a visual guide: http://www.kawasakiversys.com/forums...html#post86320
But none of the pictures load
You are correct, this was from the old forum, many posts and pictures lost, http://www.kawasakiversys.com/forums/86320-post26.html
is one of the original posts.
I started a TPS in How To Forum
, I included pictures I found on this forum, and applicable posts.
So this is my take on what is happening, since this is intermittent I feel it points to electrical. The very first thing I would check is the oxygen sensor, the plug, and look for loose connections, also follow the testing of the sensor in the manual. The plug going to the airbox sensor could also be a problem if it came loose.A to the TPS that has been a problem in the past with surging, I would unplug and plug it back in, there is a harness made for this testing of, also ways around if you don't have a harness ( you are under warranty and having a mechanic suggest it is your imagination isn't good) .
To summarize what I would do, if it was my bike and under warranty;
Check the plugs to; oxygen sensor;TPS; airbox sensor , when checking these plugs, check the individual wires going into the plug, each wire has a crimp and retainer, I have seen it where the crimp is good, but the pin wasn't inserted all the way into the socket, ambient temperature changed expansion rate, wire tie held everything in place, even though one pin wasn't inserted correctly, sometimes it worked other times not, so look at the end of the plug and see if all the pins are the same distance from the end of the plastic.
Follow test procedure for oxygen sensor, record results
Check frame ground and engine ground
Take it for a ride, see if the problem still exists, if yes, leave it with the dealer, anything you found that seemed off, like the oxygen sensor, mention it. That is what warranty is for, normally I wouldn't suggest any of the above, however seems like your back is against the wall.
