hello im new to kymco

[mudfreek]

i have looked all through my manual and i cant find the location of the slow jet

[zombie]

It looks like a brass tube in the front part of the bowl. Remove the mix screw, and try blowing some carb cleaner thru. It MIGHT blow any sediment out once you remove the bowl. Just don't stare at it when you do. It'll spray out of places you don't expect.

[wordslinger]

ive figured out where the main jet is and in the service manual it only shows main jet and slow jet

..huh??

[wordslinger]

It MIGHT blow any sediment out once you remove the bowl

..i'm takin' this all in...

..i gots th' same carb, or similer right??

[mudfreek]

if u got a zx50 u got the same carb to my knowlige

[thebatman]

hey slinger, what i am gathering from art, your carb is different, same brand i guess but way different..

[wordslinger]

..i got the same carb as art's stock......wondering if it was the same as a stock zx...

[art]

It's the keihin pb,with the 7mm main jets,hard to get stock stuff for,i think a call to keihin is in order the only thing holding me back right now on the stock build,I need more jets! 

[thebatman]

if you get anywhere with them, let ME know...lmao...i need sum to....

[mudfreek]

could faulty reeds be part of my startin issues cause i can kick start it easier then  electro plus i noticed that there is air blowing back through the vac tube

[mudfreek]

ok ive gone through all my resistors and generator power regulator and anything that needed ohm testing and everythings up to pari went and bought brand new plugs i have puta a new plug boot on it and trimed down the wire for a fresh conection i put a new cdi i have blown out every lil nick and crany in the carb and compleatly flushed it out new vacume fuel pump/pitcock thingyfresh fuel filter and vacume lines iol injector is in the check lines so im not over oiling or under oiling my plug is a nice brown color but when i had the old fuel pump on the bike it would still run with out vacume to it ind i would get air blowing back through the hose any ideas

You should check the spring in them anyways while your in there. I'm not sure what it's called or the procedure for doing so, but I'm sure there is one.

OR

If you just want to check the price on them & slap a new set in (they shouldn't be too expensive) it can't hurt.

[mudfreek]

spring in what may i ask

[robmsz]

The spring (if thats what you call it) in the metal reeds.

I'm  guessing here but the only way that you would get "blowback" is if the reeds don't have enough ?spring? in them?

Hey guys, Sorry  it's been awhile! There are "stoppers" or "limiters" on top of the reeds. They cannot fail. If you have something wrong there it is generally a crack on one of the reeds. I'm not sure what you mean by "fuel pump" on the zx there is none. One quick test for the reeds can be done with a vacuum cleaner that has a blower output. Something like a shop vac. Remove the spark plug, and set the piston to bottom dead center. Make an adapter that will blow air into the spark plug hole. Using a bungee to hold the throttle wide open you will feel air blowing out of the carb IF the reeds are cracked. If the reeds are good there will be no air flow. give it a try, and post what you get>
