I rejetted the carb and played with the idle mix screw over last wkend. Now she sounds like she idles a little faster than she used to.

I know how to adjust the speed and I know it needs to be between say 950 and 1050 but how can I measure this?

More importantly, how can I measure it for free?

 

cant help on idle speed,just wondering what size jet you are running? and mixture screw turn out?

playing with mine now was #46 went up to#48 3.5 turns and run like a raped ape

 

Wouldn't be concerned about it. If it sounds right and keeps up when you come off the choke, it's about right. If not, tweak it a bit more or less.

 

Is running like a raped ape good?[sm=yikesomg.gif]if so i need to do that to mine, I have rejeted it and screamin eagle air cleaner and now have a carb fart ever now and then, but not all the time. air/fuel screw help this? thanks

 

im interested on how the rpms can be measured for free

 

From everything I've read it is supposedly better than it walking like a virgin baboon, then again minejogs like a violated chimp.

 

Free...can't help ya there. But there are some fairly inexpensive tools that will slip to the plug wires, etc that will tell you.

 

Yeah me too, hence the thread...

 

I moved from a #42 stock to a #45 for the slow jet. The main jet had already been changed to a #175 even though I think 883's are only supposed to go to a #170. She runs great now. I am finally able to give WOT and not get sputtering!

 

It should. You can play with it at least. From what I've read you want to give it 1/4 to 1/2 turn out and then ride for a while to see if you still get carb fart. If you do then go another 1/4 to 1/2 turn out and ride for a while again. Repeat until no more farts. At this point your idle speed may seem a little high so you may have to adjust this which is the situation I'm having right now.
