Stock Main jet Size

[mr pibbs]

Howdy

I'm looking for the stock jet size and have found some differing stories.

Some folks say 82-85 on the forum.
The parts fische says 90. 
Mine came with a 90 and a ton of carbon buildup.
The manual say 80.   

I just took of the air box in favor of a pod filter, and have run both a 95 and 92 jet.   the 95 gave me a little more topend, but bogged a little.   The 92 seems peppy, but gives a little less on top power. 

Thanks for reading

Mine had a 90 jet in it stock.  It sounds like your in the right range with the 92-95.  The only way to tell for certain is by doing a plug chop.  There is tons of info on here about how to do one.  Feel free to ask if you have any questions!  Welcome to the forum, always glad to see another ZX!!!

...ditto...chops are the key, and not every scoot will run the same jet...

..too many variables...elevation, average relative humidity..even the year, or build of your scoot...

..btw, Welcome to th' Forum!!!

idk if mr.pibbs is still around the zx, but how about fillin me in on where you hooked up wit oem style jets?!. and hows tuning it coming for you??    ive not had much luck to date finding these jets, trying to make one, buuuut

[mr pibbs]

Yeah, i'm still floating around.   Tuning is going well - the plug looks good around 92.   I got a CHT to help verify, but haven't had much luck with the sensor.

As far as jets go, they, in addition to the entire carb, are interchangable with honda elite/dio jets.   
I have tuning kit from VTcycles that i am working with.   Daywot on ebay sells some as well. 

The other way to do it is get some indexing drill bits.  The number, to the best of my recolection, of the jet coresponds directly to the width.  Therefore, a 92 jet is .92mm, etc.   

Because the engine is a clone of the elite AF16, and i started with an elite engine, i spend a lot of time over at hondaspree.net . Good forum.

Hope this helps.

...that's true as a general rule...

..some manufacturers size them differently...

[thebatman]

Hey Mr. Pibbs! These guys , and you have it well under control. Thanks for the info on the jets. Patrick (daywot) is a great guy. I dealt w/ him in the past. Some of his stuff is not as advertised, but for the most part he has a good set up!

[sidthesloth]

Got my 1000 torque spring from them. All good.

[mr pibbs]

hmm, i didnt see those at vt.....

If you are considering purchasing from VTcycles, and I suggest you do, call them up.  They don't list a lot of their inventory on the website, and they are nice guys who can help you out with anything.   

[thebatman]

does anybody have a link to daywot on ebay??  just type in daywot??

[sidthesloth]

Yeah, that might get you there, or just type in something scooter related and he should come up. I think I found him after searching for springs and again looking for a coil.

[thebatman]

thanks sid, hope all is well on your end.. idk, i may have seen him before but not paid any attention. BUT, i fo have a ? for YOU since you popped up. i was re reading sum of your posts. when your piston seized i saw your plug. was the chop the only time on that plug??  the whole shank was caramel color. why is that? and not just ring.my chop today i FINALLY saw a caramel color but only the ring, the shank was still pretty an white...lmao

[sidthesloth]

I dont remember just now, will have a look at the thread when I get home and see what I can work out. I was getting som funny colours but that may have been the oil I am using.

You're still too lean bat.
