Anyone know the stock jet sizes (main & pilot) that my 06 EG standard came with from moco?

Thanks for your time,
Doug

 

Check your Owners manual. I didn't know moco made an 06 with a carb.

 

They certainly do, or did have carbs, last year. FI was an option. Owners manual won't help with jet sizes. Service manual wont help either for that matter.

Thanks,
Doug

 

Stock sizes for your bike should be a #45 pilot and a #190 main. If you are planning on a stage one type upgrade, leave them alone and only replace the needle with a 27094-88 and then adjust the mixture screw.

 

Thanks mrgrinch,
Yes I am planning a "stage 1" upgrade. Thanks for the jet numbers.
As for the needle you recomend, is that not the "sportster" needle? I was under the impression that this needle comes from a carb with no accelerator pump and that using it in a carb with an accelerator pump causes a very rich condition during accelerator pump conditions. Is my impression full of crap?
Thanks for your time, I appreciate your response.
Thanks again,
Doug

 

Yes that's the sportster needle with a taper for no accelerator pump in a sportster carb. But it works great in a bigger Kehin. The different taper makes the fuel delivery stronger during acceleration without creating a too rich condition. After shimming stock needles in 3 different twin-cam bikes, I tried the sportster needle and prefer it. No more sooty black pipes and better engine response. On the jet sizes, the 190 is already plenty rich because the EPA does'nt test at WOT. A lot of Harley dealer mechanics switch out the 45 pilot jet for a 48 in a stage one 88" motor. They do this to cut down on decel popping when the throttle is closed. The mixture screw meters fuel through the pilot jet, so an adjustment to 2.5 turns out to start alleviates the need for the #48 jet. I've heard it was illegal for them to remove the plug to access the mixture screw which is why they swap in the #48. More likely it's just quicker and easier that way.

 

You know about the "hidden mixture screw" located on the bottom of carb behind a metal plug, drill out the plug to see the screw.

 

Thanks again mrgrinch. I have also tried the "shim" method that richens it up ALL THE TIME.
I will give the "sporty" needle a try, thanks again.

gunrunner, thanks, ya, I know about the "hidden screw" After putting on a set of Bubs cross dressers and some Rush 2.5s the mixture screw totally illimated any popping on decel (right at 2.3 turns for me). Now Im putting on a Big Sucker and thought the extra fuel would be a good thing.

Thanks guys, ride safe,
Doug
