Ok, so this is seriously just a question, I got way too much on my plate to be doing any more modifications right now.  But I hear a lot about jet sizes and I am curious about mine.

I know for sure that I have the 145 main jet.  The other two up top of the carb I am not sure of.  One has a what looks like 230, or it could be just 23, but there is another stamp that just doesn't look so deep as the 23, almost positive it is 230.  The 230 leads down to the chamber on the side of the carb with the small diaphragm.  The other jet has a 45 on it.

So what is my set up?  Is it stock?  I live around 1000-1500 ft.  I live in the Ozarks, so the terrain varies greatly. I am just curious about it.  If someone that has fiddled with these things long enough I figured they could chime in and make some comments or something.

I almost got the bike back together tonight.  Not much to go, had to quit early and have some family time.  Air filter, gas tank, clutch cable, seat and I should be good to go tomorrow.

Ahhh...thanks  When I was cleaning my carb I couldn't for the life of me get the pin out that holds the bowl.  So that figures why I did not get the numbers off the one underneath it.  I am almost positive its stock because the white spacer mod had not been done and I would figure it would be someones first attempt to messing with a carb.

the 2 jets you found on the top are "air jets" and the one is a #230
do not change those jets, just clean them before reinstalling

on average, most Savage/S40 machines with a HD dyna or sporty muffler run well with a #52.5 pilot jet and #152.5 main jet, with the white spacer (or 3 washer replacement for it) mod, and proper adjustment of pilot air adjusting screw

there can be exceptions but most do well with that setup

by the way, my mantra...as always ... be sure to clean EVERY little passageway in the carb body or it will not react properly to tuning efforts and will frustrate you
