Hawk pilot jet seems I may have found it

Samples coming time will tell

As I said on Facebook, I would be very interested in a few of these. 48, 50, 52 and 55 to be specific.

These should also be for Sheng Wey PD10 carb.

The thing with Chinese stuff is to use visual comparisons as there are so many brands or names or makes and models there's just no way of telling them all - but when you look and or measure you can see it is the same etc.

I’ll be adding in the funky pilot jets to my kits and optional extra larger at a nominal costs
So you could add in more of any 3 styles of pilot jets at time of purchase of the first tune kit

I won’t be selling only jets - too much drama etc

PZ30B kits with all trimmings options jets and what ever option you might want is also here, no more searching jets as it will and can come as you want (mostly) and also I think I have the cable for the TT250 with the elbow that suits the pumper carb etc and several ways to have the fast turn throttle on either the stock carb Minkuni carb or pumper carb

Maybe easier for you to buy that jet alone or some drills to drill it.

I just ordered the start up kit and the valve adjustment kit. How much to add the extra jets before you send it off?

Ah you order just packaged - If you wanna wait a day or 2 send a message on what extra you want etc? Make it happen all at once

I’m hoping they fit all the weird pilot jet carbs
Only other I’ve found is CCW at $16 and only #45
I’ll see what n how I incorporate the jets to my items on eBay etc
Still difficult to get but if I do it right and have a way to offer the extra jets with my carb sprocket set I think that will cement the idea of just tuning the stock carb as I see that being the more or most logical and cost effective means to tune the new bikes
Starter kit and optional extra jets
Then maybe also offer the pumper carb which use the starter kit jets and add in the in between sizes etc.

I’m one to say I don’t think the Mikuni path is really worth it and there’s another as good and more cost effective path to starting out and upgrading the carb later on
Just my thoughts etc
Each to their own

Yes, I agree. 5 years ago the Mikuni clones were about $25. Now they have gone way up. I've seen them offered as high as $45. I suspect that this is the old story of "all the traffic will bear." Amongst other descriptions of this kind of thinking the one that stuck with me was "The Harvard Business School Method", which has been described as "make parts as cheap as possible, and charge the highest prices that you can get away with." Basically all of these carbs are close to the same, the only real difference is the availability of parts, especially jets. Quality jets. Quality means that all the jets of a certain catalog number all flow the same amount of gas, air, or light. However they choose to measure them....ARH

Mikuni clones are less common in China so cost more in China
Keihin is half price to Mikuni local markets.
Mikuni became popular in the USA cause someone said to use it n everyone followed.
Keihin clone is fine too and pumper near same price and easily get jets for it

I'm one of the guys who recommended Mikuni conversion, and now I'll tell you why. BECAUSE GENUINE MIKUNI JETS ARE EASY TO GET IN THE U.S.A.! Keihin jets have been hard to get ever since they arrived here on Hondas in the early 60's. I mean factory jets, not something from Uncle Pootie's Plow Works. You're the first guy that I have heard of that actually knows where all of the bodies are buried over there. Personally, I have high hopes for you in this business. You know where the good stuff is...ARH

I agree with this 100%. Mikuni jets are very easy to get your hands on at a local level in the U.S. I would argue that it is possible to get genuine keihin jets easily enough through the magic of the internet, but I will counter that argument myself with the fact that it sucks having to wait a week to get a $7 jet in the mail.

My other Mikuni is better argument actually comes down to the jets themselves. While Keihin rates everything by bore size, most Mikuni jets are rated by flow rate.

Depending on the jet type it will either be in weight or volume, but as an example, a 25 pilot jet means that the jet is tested and rated to flow 25cc's or 25 grams of fuel per minute. This actually makes it possible to calculate jetting sizes based on mass air flow through VE, RPM, and even atmospheric conditions - think of it like analog "ECU tuning."

That said, I will also argue that Keihin's jetting system does provide more size graduations through the scale, and that lends itself to a higher degree of fine tuning. Often you will find that there is an extra jet option for a given range of Keihin jets vs. Mikuni - usually 5 in a given range to 4 for Mikuni in equivalency.

Think of this
Fake mikuni carb genuine jets.
Fake keihin carb with good quality jets from a prof supplier
You are right there’s a difference
$0.98 isn’t $1
All I’m saying there’s so little in it for the 90% of bike owners who have little to no skill level
I’m not bashing you or anyone at all but the real improvement of very small would or could only be noticed by maybe 1% of users?!

It’s like TV A has better picture then TV B
You can’t see the difference unless you put them side by side
You couldn’t show or say if yours is better then mine across the internet etc

I’m happy with TV B even tho you and everyone says it’s not as TV A

Don’t get me wrong I’m not saying you or clone Mikuni is wrong but I do see better options for something that is so small that almost no one would ever know in reality, unless it’s a “feel good” thing.
Finding jets isn’t needed as they all come one way or other with my stuff,
Stock carb n first tune kit works together with pumper carb, if hooking up pumper part is confusing then don’t, use stock cable tube carb till you have time to learn more. (So close to Minkuni route).
So from stock to upgrade pumper it all flows and if you lack skills you simply tune the pumper without the pump like mikuni etc - idea based on 90% of users idea and no the % isn’t a tested statistic etc
So let’s say $75-$80 you can tune stock carb as well as but the pumper carb and have every pilot jet you might need and every main jet you might need and have an NGK plug and have a 17T sprocket and have soared to repair your carb and maybe have a stock air filter for hawk and have 1/4 turn throttle and twin cable.
If you get a bit confused about pumper set up you could pause n just use stock single cable n tune as a PZ30 carb, learn more then go back n work on it more to gain a fully function PZ30B pumper, or you have enough to make run fine on stock carb and an upgrade ready once you learn more.
Prob end up with both carbs tuned just fine and could sell the stock carb few jets to recover some costs

I mean the options are near endless etc.

Yes the true genuine parts in the hands of a professional with skills are better then copies in hands of a DIYer, but decent parts at a decent price will be enough for 90% of DIY Chinese bikes and bike owners

All numbers or statements made are a general observation not statically or scientifically proven

[Megadan]

Having gone through tuning the stock carb, Mikuni, and this PZ30B, the Mikuni is by far much easier to get running properly. but it is far more expensive, and if you can get your hands on these jets in a few sizes it will definitely go a long way to making the stock carb a much more viable option, because that will eliminate the one real drawback to it, no pilot jet options.
