Question about 2005 Harley Davidson XL 883 Sportster
We have just changed the baffled original exhaust to a non-baffled exhaust which now makes a wonderful noise but the engine idles extremely high when cold (for about 10-15 minutes) Can this be rectified?
Not sure when the Sportster went fuel injection (it was later than the big twins), but if you're still running a carb, there should be an IDLE SPEED adjustment screw, that does as the name implies.
Also, when changing to a more free-flowing exhaust, it usually leans out the mixture, so some adjusting of the carb's idle MIXTURE screw, and rejetting is commonly needed.

changing the air cleaner is like installing a stage 1 kit, if you have not replaced the exhaust but plan to, do it before you have the ECM redone.

You will have to get a service tech to attach a scanner and read the trouble codes. They should be stored in the computer memory. It should give you a starting place to diagnose the problem.

Lots of bikes make a clacking in the transmission , especially when cold at idle. Basically the engine accelerates and decelerates between each piston firing, and you hear the backlash in the gears slapping back and forth. Without hearing it I can't say for sure, but find someone else with a similar bike and see if it sounds the same.

did you upgrade the air filter and the module for the fuel injection.the minute you change exhaust it messes up the 02 sensor,and the map readings etc.
