my zx50 issues

[thebatman]

no, i seen that..member this is a 90 but i had cleaned the hole out to big supposedly on my last carb,(b 4 pipe, etc..) i was using it, it was a 90 till i removed debris...lmao, i thought it was same size i guess...

[Shaka]

That's right!  You can try it.  If it is too big you need to get some small drill bits or torch tip cleaners to open it up.  That way you'll know what size it is!

[Shaka]

It is very minute!  Do you have some digital calipers you can measure your bits with?  I'll pull that 90 jet back out and measure it for you if that helps.  I just checked my Arreche jets out of curiosity and as I suspected the numbers don't correlate to the hole size.  I think those are one of the jets that are sized by flow and not hole size.

[Shaka]

Just checked the Keihin is based off of hole size.  My 0.90mm bit fits real snuggly in the 90 jet. 

[Shaka]

It is tight, but I could squeeze it in there.  When I measure the bit it is 0.88mm which is 0.035".

i found that bit also, this jet i have in front of me, the one i took oit earlier.. i cant even get it in the hole... i used a sewing needle too, the needle eye caught this jet and stopped, the other it went thru fine, hair to spare

[thebatman]

well today i was gonna test that other jet, sounded good on center stand, took off, i could tell already, slower, not the revs as before, boggish, turned around put oem back in....i got sceeeeered, idk what to do soooooo.... runs better since i changed back...lmao

That plastic spacer is an insulator.

That plastic spacer is an insulator.

Insulator for what, vibration?

Do a plug chop just to make sure you're in the "safe" range.  Keep in mind you are running the stock cylinder, so you're not going to get a SCREAMING fast scoot no matter what!  All you can do is tune the carb properly which will get the acceleration up a little and help the cvt perform at it's best.  Then the cvt tuning will really help improve your acceleration.  You can only get but so much out of the stock engine!

Insulate from heat I do believe

I know my intake manifold gets SUPER cold!  It has iced up in the winter!  That doesn't make much sense to me.  I could see for vibrations, but not temp.  IDK what that part is really for?

[thebatman]

she was slower, boggish, no rpm... 3/4mi, turned around, no point in a chop didnt figure.....wasnt better,,,,was worse

[Shaka]

That was with the bigger of the two jets, right?  You put the smaller one back in now?  You already did a plug chop with the smaller one and it was slightly lean?  You can try soldering the larger jet back closed and re-drilling it smaller.  Keep in mind it will run the best with a slightly lean condition!

The jet in my stock carb was an 85, when I took it out to 1mm it was too much. with the stock cyl. the slighest increase in size will make a big difference, especially with the air box and 14mm carb. Try going up in a smaller step.

[thebatman]

hey shaka...sid..    yes, it was the bigger jet, worse, yes i put regular one back in...oh hell, idk bout soldering the jet, sh** i can barely understand sum of this anyway...lmao             R THE COBRAS ANY GOOD???   LOOKED OK, LOOKED ALL STOCK WIT 34,000km  FOUND ONE PRETTY CHEAP,
