the one on the left appears to be a keihin 152 hex-head mainjet, and the one on the right is a pilotjet, maybe a 42?

I know from experience that the core does affect jetting. I would guess that it changes the main by at least one size.

hope ur pipe goes easier than my did mine was a b!*ch and it still aint right got a small exhaust leak but it does sound off!!!!!!!

[rooster400ex]

ok i got it on i didnt do any jetting yet, would it be okay if ran ran without jetting for a while?

[phildogg]

I would go ahead and jet it to be safe..its not a hard job at all..

[rooster400ex]

yea i would but my dad doesnt really want me messing with thhe carb, i dont know why so dont ask, and i just wanted to know if it will cause any harm

[nosliw]

yes it will cause harm. either jet it or leave it off until you can get into the carb.

[rooster400ex]

ok thanx

[rooster400ex]

will it run lean or rich or something? how does it hurt

[440_Turtle]

Its going to be running lean and hotter than it should so just get it all done at once and you'll be happy

If you have to ask what jets are, I'd suggest having someone who knows how to do motor work help you or taking it to a shop to install. Not being a d!ck either, it'll save you problems if you don't know what you're doing.

[coryatver]

You gotta learn somehow but having someone that knows what there doin around helps a lot:cool:

take off ur damn rear plastic.....shut off your gas......unbolt part of ur gas tank and support it so it stay up....reach down loosen the clamps on the carb.........pull car out of boot.........flip carb over and take off the bowl ( the very bottom of carb ) .........the jets are right there......unscrew them wtih a small wrench and screw teh new ones in. install in reverse order...

Correct, it is easy if you have a bit of knowledge on the subject and have done it before. Asking what jets are does not sound like he has a lot of experience in that area. Mearly just a suggestion if he at least had someone come over that has done it before to show him how it's done.

You can still learn by doing, just take baby steps.

[PismoLocal]

tell your dad to chill out, i could teach a monkey how to jet a 400ex carb.
