Kit 1: Stock optimization kit - Basically what you already offer. Needle jet and a couple of main jets. Usually the stock pilot jet is plenty sufficient on a stock bike and its the idle mixture that needs set properly. The Hawk usually comes set less than 1 turn out as an example. I think your idea of a 42 and a 45 pilot jet is a good idea just in case the stock pilot happens to be a bit small for some guys. Kit 2: Call it a "tuner" kit for guys that want to do upgrades (Exhaust, intake, etc). Same basic stuff as kit one, but toss in two or three more larger main jets (112, 115, 117 and maybe even a 120) as well as a 48, and a 50 pilot jet (on top of 42 and 45). I would personally want all of the jet sizes I just listed. I like your idea of a "First Tune" kit as well. That is a very good idea. Offer all of the tools as the base, and give the option for the first or second carb kit. I know that somebody like me, a person who is going to go to town upgrading their bike immediately, I would order the First Tune kit with the second carb kit right off the bat, even if it was $50-60. It would be worth the cost! If you offered all of that even I would put a link in my signature for it! I know you are looking to offer the basics of what you need to keep the cost reasonable to the end user and not "waste." As somebody that has tuned carburetors for a long time, I can tell you that there is no such thing as waste when it comes to jets. It is a GOOD thing to have extra jets of different sizes on hand to be able to adjust for climate and altitude changes. Heck, offer it all with a handy travel case with a screw driver and a 10mm wrench so we could zip it up and toss it in our bags and have an "on the go" tuning kit. Lastly, either kit for the PZ30 based carbs will directly translate to the PZ30B. The one exception would be the fact that, like the stock carbs, the pilot style varies. This is where just a jet kit would come in handy. Say I tune my stock carb, get a PZ30B and find out it has a different style pilot jet. It would be nice to be able to order just a set of pilot jets.

Yes I agree with Dan, those would be a couple good options. At first Tako I didn't like some of your marketing tactics, but I understand you were trying to get a foothold lol. But the value incredible and I will definitely recommend your kits.

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.

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 |

The pumper carb route is honestly my new favorite, but a well tuned VM26 clone is pretty darn good.
I don't think there is much skill involved in setting up the pumper either. It's literally adjusting one throttle cable and an adjuster screw to get the timing of the spray pattern correct. I am actually considering making a video for my Youtube channel just on the pumper and how to set it up. I am just waiting on new batteries for my Go Pro since I let my last ones go flat (oops). Once I have that video made I will be making a thread with all of my previous "adjustment" information from my bikes thread and making it a one stop shop that I can link in my Information page.

Don’t get me wrong
Your bike your money etc Just looking to offer a good thing for most people and make a buck - not hiding the facts etc. My system should relate to almost all bikes or ATV with a 200-250cc air cooled engine with the piston going up and down so vertical, not only a few know model names as you need or should focus on engine type n carb type etc.most consumers will find this will relate to them. Ignore the brands and focus on parts used in china bikes as that opens up more options or repair ability But it sure would help all if the systems shown are more valuable or viable so good choices can be made regardless if: Tune stock carb with a few simple bits like washers bolts jet etc My first tune kit and extra optional pilot jets Minkuni clone & genuine jets Add on to my kit the PZ30B pumper and more pilot and in between main jets from first tune kit. Then you have other carb options and this list can go on and on. |

I’ve sold 90 or so “first tune kits”
I call that some success If I can improve the set and system as well as have near every China bike and ATV owner see it this number could become endless maybe Or where to show the system once I’ve got it locked in? I’m not American I’m not that familiar with that market be a long shot. But the principal I’m sure is great for most. |

I think as time has gone on, information has been collected and preserved in place, and there are more examples out there of these bikes being reliable and viable options the number of owners will steadily increase. I know I wouldn't have even considered the Hawk until I watched a few Motocheez videos and then ran into this forum and did some reading.

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.
