Okay, so I don't have a trike, it's a Harley 2014 Ultra Limited.
Configuration:
103 Cu In Water Cooled Heads
Vance and Hines Power Duals
Vance and Hines High Flow Slip Ons
Harley Stage One Air Cleaner
Dyno'd with a Harley Race Tuner
Symptoms:
When the engine is cool (Even when air temp is like 65*) for the first mile or two it will cough and sputter if you go to 3rd gear or above. The rpm goes up like it is cold and will come down fairly quickly unless air temp is like 20*,then it seems to stay up awhile longer. Keep it in 1st or 2nd and keep the revs up, about like 2500 rpm, and it seems fine. After a mile or so, IE Engine warmed up, it runs very well. Lots of power and pretty good gas mileage. IE, 48.8 mpg at 65-70 mph. Haven't gone on the Highway yet.
The bike runs really well once it is warmed up, maybe a tad of popping on decel, but, not terrible. I'd hate to spend the money on a Power Vision and find the tune I have is good.
Any ideas what could be causing this? Oxygen Sensor? I'm kinda at a loss. Most of the things I've come up with, in my mind, would affect the running all the time. Tune is all I've come up with.
