Good to hear that you are up and running, I'm still trying to work mine out, she must be a woman.
Don't forget to put up some pics so we can all see it. Also some pics of the stripping and building as well,
will help someone else down the road.
Remember, no pics, it never happened.

Oh yes, you can tell between the next r or a rs2... the size can tell that....
Good to hear it's up and running.... but they don't make a "90cc" kit for the ZX.....a mina has a 90 but not kymco

[Pattyboi33]

Ya they do it's rly a 82cc. An Sid sadly enough I'm on my I phone an I can't post pics :| but I took her out today an she soft seized so I need to play with the jetting I'm running a 32 /1 ratio an It smokes heavy but it still seized

[sidthesloth]

What size carb and main jet are you running? When you put the cylinder on, how much of the transfer ports were open? This seems to be the same kit I got first up.

[Pattyboi33]

I have a 28mm oko power jet the one with that line that runs from the bowl to the nipple in top where the air cleaner goes it's got a 130 main and a 39 slow with the needle clip allthe way botom setting an the transfers were very close to matching I olny angled them slightly there was maybe an 1/8 inch I removed an I shaved a very very small bit off the piston skirt it came way to close to the cases at top dead bottom center infact I think I did hit a Lil but that's all taken care of now . I think I need to up jet the main should I mess with the slow to ? It idles like a dream. Hmm I'm not sure what to do also how does tha air fuel screw work is it turn it in and it's lean an turn out it's richer ? Need some help deffently I wanna do things right !

[Pattyboi33]

I mean it ran sick with no bog at at all from closed to 1/4 throttle an that's all I'm runing it at the moment because I'm still breaking it in

[thebatman]

Is your needle in the 1st slot or the 5th slot?
I'm trying to master this fine tuning crap also, it seems on some papers i have that if the needle is in the 1st slot(all the way down), then you need to downjet 1 size, if it's in the 5th slot(all the way up), then you need to upjet 1 size, i'm prettyy sure that's who that goes....

[Pattyboi33]

Yea that's how it goes but I up jeted from a 130 to a 135 an it still soft seized btw how did u break in your motor

[thebatman]

When i finally got her together. .. I ran a few heat cycles on the stand and actually rode 1/2 throttle? for 2 tanks of fuel, then WFO every chance...

[Pattyboi33]

An it hasn't blown up I thought break in was like 500 miles befor u start beating on it

[thebatman]

No sir.... I actually did the same thing when i was "building" it stock....Works great.
I even did that with the s9 i recently built...

[Pattyboi33]

Hmm that's interesting right now I'm dining dangorisly lien but that's nothing I can't fix if I keep the choke on every where lol that makes it plenty rich lmao

[thebatman]

Oh my, we dont want that...
Time to upjet... i think id go up on both jets and see...(i'm running a 45pj atm)

[Pattyboi33]

Sounds good time to order jets!
