Never had similar problems with any Harleys I've owned, so this is interesting to me, for that "just in case" future problem should it ever arise with my current bike. tp

running bad
Just an idea, but my bike was running like crap a few years ago and it turned out to be a very simple fix. The exhaust flange bolts had come loose and it was letting the engine suck air in thru the exhaust flange area thereby fooling the exhaust gas sensors. Check them and if they are loose your problem will be solved.

I did take it to another dealer and according to them it was running very lean (18:1 AFR). I do find that a little tough to swallow. They apparently tweaked some settings and flashed a new map. I saw the dyno print out and it did appear to make some improvement.
However, it hasn't seemed to have mad any improvement in the heat issue. It is still running much hotter than it did 6 months ago. I purchased an UltraCool oil cooler hoping that might help. Nope. Perhaps some LoveJugs - but I shouldn't have to spend money on those types of fixes.
The heat coming off the engine is almost unbearable in stop and go traffic as well as engine idle performance is in the toilet. I have to keep rolling the throttle to keep it running. Of course that just generates more heat. Catch 22. It is getting to the point my wife doesn't want to ride with me any longer. She has noticed it as well. Big time.
I guess I'm just going to have to wait until something finally breaks to discover what the problem is.
Thanks for your interest.

I'm just not handling this well at all. I'm pi**ed to say the least.

Sorry for the late reply. Was out of town for a few days.

It would be nice to know what the AFR was after the tweaks. No way in hell should you ever be running an AFR that high. That is too lean. AFR should be < 14.5:1 at idle and decrease as you increase load on the engine. That most certainly would explain the excessive heat issue however it doesn't explain why the AFR was so high. I think your problem could be related to the fuel system if you can't locate any issues with the intake / exhaust system and assuming the tuning is correct. Has the fuel system pressure been checked to see it is correct and are both injectors working properly? Keep us posted and good luck.

Although my cell doesn't do a great job with video, I recorded this short segment moments after it started knocking. This knocking started approx 1 1/2 min after I pulled into the garage from a 50 mile ride this evening. I can make it do it at will but the Harley guys can't seem to be able to make it happen.

I'm completely frustrated and am almost convinced I should just ride the da** thing and let it break. Then they will have to fix it. Only problem with scenario is Murphy's Law say I will be a very long ways from home when it happens and of course my wife will be with me.
I'm just venting now so I better stop.....
Thanks
