Don,
Did your SERT tuner measure your static cranking pressure, and if so, what was the result? Your symptoms sounded like they could have been attributed to high static compression pressures, but one could not rule out tuning until your recent change to SERT.  My next step would be to check cam timing.  An intake cam installed with too much advance will decrease duration and cause increased static pressures leading to detonation issues.  The higher pressures also explain your earlier 119/119 performance numbers.  If cam timing is ruled out, compression related hardware (pistons, deck height, combustion chamber size, cam measurements, etc...) will be the next logical diagnostic step. Unfortunately that will require a top end tear down, and as you mentioned is best left for the winter.  Good luck with it.

HDFR, the only answer I know right now is "yes because I was told so."  The bike was there most of the time and I wasn't.  Tending to some health issues with my mom.  Tuner is going to write up notes above and beyond our phone conversation and get them to me first of the week.

Your thoughts echo mine pretty much exactly though.  Doing much further diagnostic will require some greater or lesser amount of tear down either on the side or the top.  Other things going on now and, priorities being what they are, I'm just going to choose not to mind it being a winter project to look a lot deeper.  Just not a big deal right now. 

I have at least isolated one system from the other.  In and of itself that is progress.  So now it'll just be baby steps until I get time to look deeper.

Rhino, you've gone out of your way to offer a lot of advice.  Things like:


.......

Ya know there Donny, I think you just don't really get it. No matter how much you blather on, and how much you think people are picking on you, not once did you ever respond with a result to me, on any of the readings I had been requesting. ..........

Gentlemen I think it's about time to let this go.

Don has problems w/Zippers not w/you Rhino even though you've offered your assistance you can't make someone accept it. Not saying that was the case just saying all you can do is offer it, and it is up to the individual to accept or respond w/the information you are requesting. If they don't then it comes a time when you just have to accept that your assistance is not wanted/needed and walk away.

Continuing this thread in the manner like the two posts I've quoted will get the thread locked down. If you two need to air your differences please take it to PM's. Thanks.

Edited To Add: Thread is now locked.
