MY ZX50 O.E.M CARB TUNING

[wordslinger]

..i "shaved" the retainer by rubbing it back and forth along a fine file...

..same thing with  the needles head..

..and yup, it'll gve u a richer fuel mix fuel during mid throttle, and a bit more at idle too...

[thebatman]

i have, according to torch cleaners, a .052in play in my needle as of now.      pushing needle in against its spring gave me the .052in.    do you want any play in the needle or would you want it tight?..... i wouldnt need to cut/trim anything to "raise" my needle really do i since there is a .052in play......

[art]

I went as far as possible the first time  and was pretty good till it got hot I think one(beer can) will work,depends on mod and stuff 

[wordslinger]

...you do want some play, so your needle wont constantly rub the side of the atomizer in the same place all the time...

[thebatman]

i thought a beer can was the same as a drink can, which is .005in thick...wouldnt that mean 5 shims to get that .025 you mentioned( be about half the play)

[wordslinger]

...the logic is, that the more beer (shims) you consume (use) the higher you (the needle) gets...


 

[thebatman]

high? take it higher than a birds pussy??       ...so i guess if this was done, then my jetting is gonna be off again too?    could you tell a difference tho??                                          METAL CONCERT ON 105.9.....testament....anthrax.....FK YEAH!!!!!  (seen em both btw in person..lmao)

[wordslinger]

...bat, you would not get along well with scosgt...

 

..if your jetting was good before, then you wouldn't need to do this anyway...

..it really won't affect WOT...

..you might need to increase air flow a little at idle...do your chops during mid throttle, and see what your plug tells you, as well as how it runs during mid throttle..

..

In a perfect world that is true ,try to flatten a beer a soda can and have it hold it's shape. Buy the time you bugger all the ends to make it fit the hole it's perfect. If not make another there cheap me and word can't give  em away!  

[art]

You must get authorization in scuzz's world before the beer can shim install can happen. God may strike you dawn if you don''''t.

...lmfao... ...... ....

[thebatman]

well, with the way she ran today, it seemed ok but i really dont know what the max from this carb COULD be anyway, it is a 14mm....lmao. ...according to the shift pattern, mid seemed good once i was in the "powerband" i guess, it was making power...lmao...i was a bit lean at wot before, hadnt done any other chops anymore cuz the pilot jet never changed, so i figured it was still lean as before.......        i would like to think there is still some power left inside my carb to harness.........

[wordslinger]

i was a bit lean at wot before, hadnt done any other chops anymore cuz the pilot jet never changed
so i figured it was still lean as before


..the pilot jet only effects idle, and just off idle acceleration...

..main jet governs WOT, and if you're lean there, then that's a bad thing...

[art]

Back to i think the topic. by increasing the needle performance you will have some gains for the cvt,for me i wasn't making the hp at the right time I had top to spare but not enouph umph to keep up with the cvt in the off idle and mid,so no nice smooth transition all or nothing baby it did work just not well  Does that make sense?

                                            now hang on homey, i have it in here somewhere, YOU have even said they run better when a bit lean..you had waited on shaka(i think) to say it first.......  i do need to do a few tho..if my cvt stays good, i would like to tweak(if possible) the carb somemore...
