While I am a little disappointed the numbers were not higher, other than saying, “numbers vary from dyno to dyno” there were a multitude of things working against a good tune. We were under a time crunch for me being at work the next day (got home at 1:15am), there was a severe thunderstorm rolling in, the engine was tight with only 50 dyno miles on it, and despite what the graph says the ambient conditions were ~94F with ~70% humidity. So, I believe once the engine has some miles on it, there is additional tuning work to be done.
Shortcomings?…
A consulting engine builder (on this forum) does not like my pipe/muffler (vs. 2-1 & baffle size/style) choice and my actual engine builder does not like my intake (vs. HPI 58mm) choice. They believe I have left easy power on the table, but both components were reused from my previous stage III build. I would love to hear CVOHarley.com opinions on this.
Things I am noticing after one ride, first the good…
Significant power increase from my previous stage III build with Fueling 574 cams! Two-up ridability is much improved as torque starts much lower.
The not so good…
Excessive valve train noise (wife said, “what’s that noise, I’ve never heard that before?”)
Excessive heat (on +90F day, wife said, “is the heat always going to be like this from now on?”)
Weak link…
Stock bottom-end with .0035 crank run-out
Please check my signature for specs before asking redundant spec questions.
Oh, and surprisingly my pistons were .007 (instead of .004) in the hole. So, .027 HGs (instead of .030) were used to compensate.
Thanks,
