MY ZX50 O.E.M CARB TUNING

[art]

You'll get it,just try it tell us how it went,catch ya later i'm out too

[thebatman]

well i am back for another mindfk..lmao.... i tapped out my jet to what i thought was gonna be a .037in/.939mm with the torch tip: well my .038/.965 micro bit fits in the hole also.....hmmmm.    anyway, went out on a chop, the porcelin could see a tinted fraction, but the mix ring was a deep chocolate?? color..                  isnt that to big?   i could tell she WASNT quite as peppy as yesterday, AND she died out going down the same hill for all my chops and i could actually hear a very TINY "backfire"?? i think, 2-3 of them coming back.... i am thinking of going back since it was peppier, no "backfires". even tho its a bit lean i guess, maybe more than a bit since my 50mi ride still showed a white plug..... what is YOUR take???

[art]

You  are right at the edge hair ritch they start to sputer when ritch,don't pay attentiont to the size of jet so much with the torch tip cleaners,I't more like your widdling a perfect jet size.I say hair smaller your there.Of corse its easier to widdle more out than put back in 

[thebatman]

well crap, again.......... i was hoping shed be dead on today.... better find my solder

[art]

          got to run too more weight for me before they close!

[thebatman]

better hurry....no shops open on sun. here, close at 1 sat.   

[wordslinger]

well my .038/.965 micro bit fits in the hole also.....

...we, us human beings, can't hold the bits and files and jets in true alignment...to be able to drill to .1 mm deviation..

..i generally drill with a smaller diameter drill bit than what i really want, then verify the size with the next size or two larger bit's non-fluted end...

[thebatman]

well, i guess that makes sense..lol  but how do you get the size you WANT??    guess tho, only one swipe thru with the torch cleaners unlike today when i went back and forth a few times. cause .914 a bit lean, .965 touch to big.... may just have to run a bit lean....had been anyway(for the MOST part).... at least it will be a touch easier THIS time.... (i hope)

[wordslinger]

..it takes a few trial and error "files" to get th' feel for what yu're drilling...

[art]

Ha! what was i thinking no shops today here either or tomarrow,Every day is friday when your all busted up like me,got to work on the stock build for a bit today atleast, bigger jets new filter and still to lean,but better,cant get the bottem quite right and can fell the belt slipping,here we go again  lots of trial and error for me,I have no patience I go big If i guess wrong it's salder time,if its close than a few times through with these.

[thebatman]

crrrrap, thats one of the bad things about this carb:  you have to take it completely off and apart EVERY time

[art]

The people not to bad I don't bolt the seet down till done(seet is never bolted down) 2 bolts an its out with the open air box,do the same with the cvt one bolt to hold cover(kickstart not recamended)and it hardly ever has all the bolts in it either 

[wordslinger]

..currently have 5 bolts in my cvt cover...

..carb removal is a breeze, and i too have the "met-in" fasteners rolling around...


 

[thebatman]

yeah, i only have a few n my cvt also... yeah, just wish they made an easier way to change jets..like the ones with the "go thru bowl"........

[art]

The arreche has that,but the bowl is screwed from the top down,total  pain to clean,get to pilot jet or needle.You have to pull mounting studs to get to the bowl screws.
