Main Jet size question

[Tri-ZNate]

What is the stock main jet in a 230 quadsport?

[Modded660R2fast]

I might be wrong but ive noticed that sometimes the main jet size is close to Half the cc's of the bike. 230 cc's probably close to a 115 or so. Not sure Just my opinion. My raptor has 660 cc's and both main jets added up to 275 so its kind of close. I just said this to give you a range and get you thinking maybe in the right spot. But im currently running a 165 and 170 which is 335 and my bike runs great.

yeah That sounds about right. My SX is 130 stock and the cc is 250. I'm running a 130 in the quadsport now with just a dg pipe. Just wanted to make sure it wouldnt be running lean.

Do a plug chop and do it properly.

Indeed, the plug chop is the best way. Stock main in my Tecate 250 is a 260...

Those guys are talking about kiehins, on our Z's and i think on the tecate they are mikuni's(sp)

[200xcellent]

modded6602fast is talking about mikunis, stock raptor carbs. Numbers vary greatly from one carb to another. My dyno jet kit main jets are equal to a higher number gytr jet kit. Too many variables for a simple rule of thumb like half cc's.

Im not saying its for all bikes because i dont know all of the types of bikes or how crazy the manufacturers built them. Its just what ive kind of noticed on my 300ex, raptor, Dirtbikes and other friends 4 wheelers. It waas just something to maybe help him out, just an idea ya know. My trx300ex was a 115 stock jet and i know have it at a 150. My raptor was like a 135 and 140 i think=275 so its kind of close to the cc's of the bike.

[Tri-ZNate]

So does anyone actually know the size of the quadsport?

[Tri-ZNate]

Well Now I know that it is indeed a 115 main. Your system actually worked on this one.

[Mosh]

yeah i guess that would work on the half the cc size, but what if ya have a banshee. lets see. 350 ccs and 2- 240 main jets? i guess the half system dont work there.lol

[Tri-ZNate]

thats why I said it actually worked on this one
