i am disapointed by my harley, really am....people say harleys break down and it is true......i have it now for 4 years or 3 years not sure and nothing was wrong....but this year, spokes broke, rear brake switch is broken and now this stuttering.....i thought i will have no problems for years and years....
Especially ones that have had tuners and aftermarket performance parts installed. Its just the nature of the beast.
I know how it seems to all come at once, it does for me at times, but running it down and getting it sorted is a good feeling. Good luck and hope you find the cause.
PS-dont ever pressure wash your bike!

Just to give update I fixed it today I think, it runs smooth af, smooth at idle, no more decel pop, the decel pop decreased for like 98%, almost not happening anymore.....
I changed the sparkplugs to original Harley sparkplugs....before I had some japanese inside NGK or something.....they were black and one had to much gunk on it, so much deposit, so I guess that is why I had constant misfire, decel pop etc......
I tried so many things, suspected so many things, next would be unpluggine the speed sensor, check for leaks in valves etc....but it was the simplest and the cheapest thing, spark plugs....
GUYS always run Harley spark plugs, they are cheap and great.....it runs now like new....I am extremely happy now...

If you clean the IAC again use a MAP sensor cleaner to clean that little valve , less harsh on the components inside the throttle body. My self I would cycle the ignition a few times while cleaning the IAC and open the throttle plate and clean the inside of the throttle body, inside top and inside bottom. Also think about installing an External Breather System to divert the oil vapors from going into the throttle body to gunk everything up again.

if I spray it inside will that go into the engine? if I open the throttle so the flap opens up and spray inside everywhere? This goes to engine right?
