MOPED ARMY

Always wanted to try one but never bit the bullet yet. They look quality.(edited)

this might be obvious, but i always tune these by going off the screw, on the PWK clones it is an air bleed so if i'm less than 1/2 turn out (going in is richer) i go down a pilot jet, if i'm more than 2.5 turns out (lean) i go up a pilot jet. if it makes no damn difference at all i just swap parts wildly until it does.

i can't give you the answer you want because i haven't played with the polini specific ones yet, but 32-38 seems to work for every single pwk style carb i put on a moped.

i'm still figuring them out, trying to tune in a 24 joko on my tccd 70, but the needle seems to really rule the roost, clip changes make a huge difference. I just bought a new genuine oko needle and atomizer. Your results may vary though because i'm on a cretin-ported piston port with zero midrange, and you're on a bike that is going to have a much flatter vacuum signal.

good news is that all the PWK clones seem to be super stable jetting wise, there are really only about 3-4 pilot sizes and jet sizes that apply to mopeds, i'm not totally scienced out on the needle thing yet but from what other people have posted, it seems like the needle and atomizer that comes with them work for most setups.

let us know how it goes, i'm gonna put another joko 24 on my parmakit a35 next.

haha yeah i've been from 20-50 on the pilot jet, i've tried 3 different needles and two atomizers, and 110 to 150 on the main. then my needle bearing explodered and that was that, dying to get back on it.

it was really shocking how little difference some of the huge changes made... these carbs just, like, work... getting them dead nuts perfecto becomes really hard because they aren't like a PHBG that tells you its unhappy.

i'm gonna try the new genuine oko needle and atomizer with the 110 main and the 32 pilot when i get it back together. i think thats going to be getting me real close. pilots from 38-50 all basically ran exactly the same, not happy but still running and really not as terrible as you would think.

i have had to drill out an air jet on one to get it lean enough to run one of those space filter boxes. 32 was not quite low enough for a 50cc

Yeah take the air brake jet out. Treats has air brake jets too.

It comes plugged. try taking it out.

i feel like i had to upjet the idle a shit ton after taking it out. Idk it's been a while.

Ok, 73cc Polini'd V1 with a 4 petal reed block, 24mm intake, Polini CP, 10x36 gearing

Main 106 or 116 I honestly cant read it

Idle 38

I hit 49 with it the other day, with room left, it was 28 degrees and I thought I was gonna turn into an icicle, but it idles great, throttle response is much better then the sha it replaced, and my temps maxed out at about 280, I'll report back more when it warms up a bit!

I will give this a try for sure, in a classic Ohio move, it has been in the 40's the past few weeks, but today we are getting dumped on with snow....

Hi Andy,

I know it's an old thread but have you got it all figured out? I'm leaning toward a Polini CP 19mm for my Polini'd V1 (also with a 4 petal reed block). What size is yours?

I'm trying to ballpark jet sizes so I don't have to buy a whole lot of ranges but they are not that common among V1 users as far as I can tell.

Thanks!

finally piked up a CP19 to put on my puch polini, excited to check it out
