Proper Main Sizing
So I have ditched the airbox long ago and have pods, the EMGO or whatever, kinda crappy but I have a budget and need to ride for now. I'll be getting K&N soon enough. What size jet should I go to?

You have stock pipes or a header?
With stock pipes and your "kinda crappy" EMGOs, maybe something 4 to 6 sizes larger than stock.
With a header, maybe 5 to 8 sizes larger.
Plan on re-jetting when you get the K&Ns.

purchase st.3 jet kit/follow instructions 100%/enjoy the results!
FYI
if you are going to purchase a 30 dollar set of filters.... disregard my above comments and continue pulling your hair out as GS CV carbs will never be able to be tuned correctly without a st.3 kit and good filters when the air box is removed.Comment

Well I didnt want to put a bunch of money into it until I could get it running and ride it, once that is possible then I planned on that stuff.
The fire has set my mood back a few days from even looking at my bike though.Comment

In general, mains are sized by 2.5 intervals. So if stock is 122.5, next size is 125. It was mentioned to go up 4 to 6 sizes or in your case 132.5 to 137.5 (maybe called 138?). Hope this make sense.Comment

Well in that case I'll go with 132.5 but what size for washers to raise the needles would be recommended?Comment

The washers that most of us use are found at Radio Shack.
They have a bag of assorted washers for about $2, the smallest ones fit perfectly. Stack a few washers to match the thickness of the nylon spacer that normally sits above the clip on the needle, it's usually about 4 washers. Start with half that many, use them in place of the nylon spacer.

Would you happen to have a part # or item # for this bag of washers?The washers that most of us use are found at Radio Shack.

I asked at my local one and they all looked at me like I was nuts.
They all three said that they do not stock any.
Thanks,
