my zx50 issues

[thebatman]

what up fellas?..i feel like sid, this dam thread just wont die.       WELL BOYS: I SHALL BOW DOWN...YET AGAIN!!!!.....i did find an air leak today, head gasket... i am right now, have motor tore apart. the head looks ok, i sprayed it and bam, died right there..have new gasket for it and reed cage gasket.....but i took off my cyl and my piston is looking a tad rough on one side, the left? looks burnt w/carbon. why the left an not the whole thing?. i guess that will be my next order then huh?. anyway, i couldnt tell the gasket had even blown when lookin at it. it even looks ok.. i also have a fkn crack in my pipe, right past the header bend. w.i.t.h would crack a pipe??.....i have evidently  gotten rid of more carbon. my exhaust port, could not stick pinky in, now index finger can touch piston?. i had thought that was oem, not buildup i even have a pic, it had a half moon shape, fk my sh** was clogged worse than even i thought.

..blown head gasket and a cracked pipe.......

..reckon that'd be a leak...dang...well you know where you are now!!


 

[thebatman]

my luck sucks ass!!..(thank god for hippie food )... well i sure hope this helps, maybe i will back on track...i want to reinstall the ported reed cage....any idea on the piston??...id love to see how big your intake opening is on either of your scoots..arent the oem carbs on your scoots a 16mm???

[sidthesloth]

Make sure you seal that base gasket. How do the transfer ports look? It is a relief to see you found the problem, as wordslinger said, you know where youre at.

[thebatman]

those ports seem to still look new ish.   i will double check. gonna try again on making a port map, failed last time. i wish i could measure 1mm to heighten my ex.port. too scared for that techy stuff w/only the one cyl. man, i hope this works, i had thrown the fixed oem pipe on and dam i missed the noise. i am gonna try it tomorrow tho, it may not be bad, except for the weight.  still gotta put this back together tonight.

[wordslinger]

..take ur time dude...you'll get it..

..you found your problem!!!

..that's awesome!!!

[thebatman]

BAM!!!... i have made my 1st port map.     ...dam, they are tiny lil things too.

[sidthesloth]

Cool, they are fiddly little things to make. See mine, pretty messy.

[thebatman]

naturally i havent actually measured it yet.   .....im still putting it back together. wish i had a hone to clean up the cyl. borrowed one but to big.. wont get my pipe back till tomorrow so i drilled 5 3/8 holes in my oem pipe(no cat.converter). at least i can tryvit anyway. want to put cage on but i guess id better wait till i make sure she normal again.

Glad to hear you found your leak!  Should make tuning a bit easier now!

[thebatman]

  WHOA.......good to see you survived earl dude...maaaaaan, i could use your input, we sure miss your ass around here...well sid and i fo so... thanks on the leak, i hope it helps buuuuuuut a few things havent ever changed tho, that drive me nuts.

[art]

  Cool! When things are running right it makes tuning the rest alot easyer

[thebatman]

well i had a crack in my exhauat pipe, so i had to reinstall my modded oem pipe..out on sone chops today, the oem pipe seems to compete with technigas pipe. w.t.h??..alot heavier than the rs pipe for sure. i am actually thinking of running this pipe a day or 2. unless i am crazy, i would dam near swear my take off is a cockhair better with the oem pipe. how could that even be possible??. unless the air leak gone and i JUST THINK takeoff is any better.   i know a few of you are still running the oem pipe...when i reinstall my rs pipe, will it lean carb out any???..i have room to play if it does.    i know the oem pipe is SEVERAL decibels quiter than my rs pipe even with the mods on it...thats crazy right there.....

[sidthesloth]

You fixed the air leak, that will give you better running, when you get your rs back you will be able to see if there is any difference.

[thebatman]

i just picked it up..my rs pipe.. yeah, i was wondering if this oem pipe or being on the ritcher side, she seems to be apporx. 2-3mph slower..didnt know if pipe, jet, was the culprit
