Proper Main Sizing

[Guest]

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?

85 700..

What's your stock jetting?

[Steve]

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.

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.

I'm going with #126 from #122.5 and raising the needle with small washers, any input?

[waterman]

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.

[Ranger]

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

[Steve]

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.

Awesome, will do. I ordered 135s instead hopefully everything will be good.

Would you happen to have a part # or item # for this bag of washers?
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,
