I can remember someone posting about this before but cant find post.
Here goes anyway. 48 not returning to idle (worse with some fuel more than others).
Anybody with ideas would be appreciated (or a better memory)
Could be the throttle friction screw. It sits under the throttle, and can get sticky, stopping the bike from returning to idle. Try backing it off half a turn. Also try a light squirt of silicon lube on the throttle assembly. Try the simple things first...TC
the bike sounds lean esp down low
Could be the IAC motor on the throttle body.
You did say that you have a 48 correct me if I am wrong but your bike should still be under warranty, take it back to the stealer.
yep probably iac control motor just did one on my iron so far fixed the prob but you should be able to get it under warranty $66 part good luck
check out workshop general page 10" dyna eratic idle" ps on friday there was only 4 left in oz ???????
Bit of an explanation below..........our mechanic told us when using high flow aircleaners they can get worn and a simple fix is to replace them (not sure if this is correct but worked okay)
IAC - Idle Air Control - An electric valve that's threaded, one turn of the valve is called a "step." It's controlled by output signals from the ECM to open and close as needed to allow enough air into the engine for starting and idle operation. (Throttle closed) The more steps, the greater the amount of air enters the engine through the IAC passages. It's that ugly looking black thing you can see just inside and over the top of the air cleaner.
