I no I should have a manual , and yes I will be getting one soon .
Should I buy the Harley original or the aftermarket brand ? (2004 Sportster 883 XL )
Now for my main question . What size Main jet is standard from the factory set up ?
I replaced my exhaust with Vance & Hines sss and added a Arlen Ness big sucker stage II AC .
Directions say to install a 175 main jet , and 45 idle jet .
I changed the idle jet from a 42 to a 45 but to my surprize the Main jet was already a 175 .
Is it standard factory installed ?
I was thinking of going to a 180 .
Seams to run good like it is and I havent noticed any difference in plug color .

Thanks for any info .....

175 main jet is stock and should be fine for your setup...
45 pilot jet sounds right too...
Just make sure your idle mixture screw is adjusted (usually 2 1/2 turns out or so)...
If it's running good and plugs look good, I'd say you're good to go, though!

Oh, and:
Of what? The manual? I'd definitely recommend the MoCo's manual if I had to have just one.
