MY ZX50 O.E.M CARB TUNING

[sidthesloth]

If you go too high with the needle it will sputter and struggle going off idle when you try to take off. That dying at speed sounds like starving for fuel, like art said, the seafoam dislodging gunk and it is being picked up by your filter. Are you getting better performance/top speed?

damm, im out trying a chop now, she died/ acted like it again..why..wtf,, never done tis before gotta get?her home now..wth??? im taking out shim and boring out jet,, wasted this plug

justvtook out this wasted plug, electrode creamy color, mix ring, mada..how can a .965 not have a freakn ring, waaaaay big....just pulled on vaccum line, gas shoots out fuel line w/vaccum....   shim was taken out for this last run,.....mayne just take out that reed cage??

[art]

  Got to go back to basics. spark to plug(nice blue) Is there fuel and does it flow at all times,air filter unrestricted. The things you have done should not kill it,it may not run good but no start .back to the basics! one of these things is missing from the picture.

[art]

White creamy while upjetting air leak somewhere i'd think or way under jetted  . Try the other reed block, I Guess .Did it run with your ported one before?

[wordslinger]

air leak somewhere

..back to that.......

[thebatman]

she started up, had to give gas..idle sh** right now....fuel dont flow at all times now, i have vaccum, remember. took 3 kicks..... all was well tl todays jetting.....this is f***in me up here..went to end of rd fine, put in plug, died within a qtr mile 2 fkn times.....all at wot.....cant ride 35miles at 1/4 throttle          why would an air leak show at wot but no other time....air leak? new to me, i could be missing something tho..

[thebatman]

i figured id be over jetted by now....yp to .965 now, but cant do a chop, she dies within a qtr mile now everytime so far.. yeah, its been in for several days now.even rode with it in. started chops yesterday, still good, today started this crap..........

  Still think fuel delivery is suspect. did you read the fine print on the seafoam Ha! Probably don't have it on there. but it is recomended to change filter after use with tanks that have not been treated with it.
  It will knock some thing loose in the tank and its got to go somwhere. If your fuel is restricted that would show as a lean condition also.
