jet kits

[cmblaster]

I keep hearing people talk about stage 1 and stage 2 jet kits. What is the difference. And how will i know if i need to go to a stage 2 kit. I am running a 240 kit that i am gonna get ported and have head work done to as soon as i get the money. I am also getting the fat bastard exhaust system and i already have the 3 mm stroker crank.

you must be hearing that on other, 4 stroke based, websites.
the only thing you'll hear on this site is......
jet kits are a waste of money, and supply you with all the jets they could not sale to anyone else, instead of the ones you actually need.

the stock carb can be jetted for those mods you have listed, but it really isn't recommended for a 240 stoked/ported engine

you'll be way ahead of the game to jump to at least a 32mm carb, with 34/35/36mm's being most popular for that engine combo. and you'll get the most accurate jetting help/info when you make that switch.

when you decide exactly what engine work, pipe and carb combo listed up, someone will get you in the ball park on jetting.
until then head into the engine/carb section on here and read as much of the carb tuning info as possible.
in the end ...only plug chops will tell you if your main jetting is correct.

X-2 on Awk. I've got a Fat Bastard on my SS SB with trail port and I love it. Hearsay that it was actually designed for your setup. When you get it all together, give your impression of it.

You may have a place local to buy jets, however if you dont this is where I get mine from they sell TONS of stuff most jets are $3 for example. This place is local to me so its where I go, but they ship all over.

Theres some other place that ive seen linked before for carb parts as well but I cant remember the link for it, maybe someone else will chime in with it.

Automatic Distributors, Wholesale to the public

/\ yuuuuuup !


but i see alot of el-cheapo places being listed here lately to buy jets from, like $3 each,
i'd be willing to bet those are not genuine mikuni or keihin jets ? which have proven to not be as accurately made, nor at metering the fuel as the genuine article.
i'd suggest caution be used when trying to jet to our suggestions, but using knockoff jets !!!!
most of the info and jetting suggestions on here are made with years of experience....using genuine jets.

is saving $1-2 dollars really worth the risk ?
not on my bikes !

Anybody ever seen a chart of the hole diameter of jetts? From one size to next is like .0005 or even smaller.I can see what AWK is saying, not much room for error. You only get what you paid for, if you're lucky

If my camera could zoom in enough I could show you these are indeed genuine mikuni jets. I do however agree with you, going with a cheapo jet is not a good idea. The place I listed sells genuine jets for just about every carb make/model out there. This place stocks like everything known to man for power sports, like I said I use them cause they are local and im happy to have them less then 20mins down the road. The building is a gigantic warehouse, when you go in to get parts the person at the counter opens up a catalog thats thicker then 2 phone books to find the numbers needed to locate your parts in the warehouse.

thats great, but no proof needed 'dred, above was just a general statement for those who keep asking "where's the cheapest jets"
as they MAY get what they ask for...a cheaply made jet, they are out there !
