nada huh? i did a search on a proper computer and got nada as well. I think its a 115 but im unsure. With my pipe im tinking of going to 120 mains and shimming the needle... should i bump the pilots as well?

Edit:this is for my V&H 4-1 sidewinder with stock airbox/filter

I only have a "Junior" GK, but a quick search of my resources shows that a stock main jet in the GK carbs is, indeed, a 115.

Depending on how "uncorked" your sidewinder is, you may want 122.5 or even 125.

Shimming the needle is good, probably no need to bump the pilot fuel jet size, though. Mixture screws might need to go to 2.5 to 3 turns out.

Ttally uncorked... lol.. Im gonna get the 122.5 and the 125 and plug chop it out. should the mix screws come out from stock or 2.5 - 3 from all the way in?

Yes, 2.5 to 3 turns out from lightly seated. You don't want to overtighten them or you could get the little tip broken off in the hole.

So its been jetted. 122.5 with 2.5 turns on the screws. No shimming of the needle as my little circlip tools fingers werent long enough to reach. One other thing i did was remove the litlle snorkel from the airbox effectively unrestricting the intake of the air but not really adding more air to the equation and now she runs AWESOME
