As promised here is the install video of my six sigma jet kit. In the video we cover how to install our pilot jets, our main jets as well as how to raise the height of the jet needle using the adjusting shims and spacers.
I also talk briefly about the slide spring modification and the drilling of an additional hole in the throttle slide.

I ordered a kit for my 92 Yamaha xj 600. I'm have a Delkovic 4 into one with an 8 " oval carbon can with a HUGE opening and running a uni filter. I'm leaned out as predicted and your vid will be very helpful when I do this in a few days. Cheers mate
Thank you, I've been watching so many videos on carburetors. Waiting for my jet kit to deliver so I can attempt this myself
Did u get it
@@geraltofrivia4651 yeah I got it shortly after posting my first comment. It worked well, it came with detailed instructions and different jets for the carbs. I don't have it anymore and that's only because I did a single carb conversion to my bike and still working on it.
I believe those 'Philips Head' screw are actually JIS screws....... so a JIS screw driver would be the preferred screwdriver if you want to avoid damage for the screws. Anyway, excellent tutorial...... thanks for taking the time and explaining it in details, much appreciated.
Я тоже повеселился на этом моменте.
Your correct Japanese industry standard Philip's head
Looking forward to seeing it all running. Good tutorial! Your video production is getting better and better. Keep up the good work!
Can't wait for the initial start up!
Perfectly explained !! Thank you!!
"Pains in that general area" I see... haha! No need PG13 here :)
Great video, this is very educational!
Good vid. got a 96 zx7r. hope to send some feedback soon when i install a 6sigma also
Great video, top notch explanation.
That Allen head screw upgrade was the best thing i ever did to my carbs! :D
What size pilot jets do you have?
Ricerguy I replace every bolt to hex head why in the world would you put a flat or Phillips is beyond me. It’s seems any carb over 10 years old the screws always strip out or are so tore up from just having to loosen them time after time.
My bike came with them already! Yessss
@@surefiremushroomsmicrogreens that's because you are most likely im guessing using a Phillips screwdriver on a JIS screw head.
Great explaining so simple looks easy do
Just got my 6 sigma kit and this is the best video on installing it around!
What size pilot jets did u get?
@@slow_carsgarage7422 Main jets included were 140, 145, 150, said to start with 140. Pilot jet they include was 48. I currently have 135, 45 as stock sizes in the carb.
@@jimellis1810 hmm they sent me size 170 and 180 main jets and size 38 pilot jet
Slow_Cars Garage What bike do you have?
@@jimellis1810 I have the Kawasaki zx6r carbs on my 4age engine
Would love a review of the jets. Thinking of buying for my cb500, but dont know if they are any good.
When screwing in both pilot jets and main jets into the carbs how do I know there set properly so I do not end up with either a too rich or too lean fuel to air ratio condition ?
Do you have to buy a bigger jet kit for the bike? If you add a new exhaust on you're bike
So in doing pilot jet install do we need to know how many turns it took to remove old pilot jet needle ? And are there size numbers for the pilot jets ? Example pilot jet # 110 per say or these needles dont have a number to them ?
Hey man my bike doesn't idle and bogs out all the Time this kit should fix it how Did this kit work for you?
Well done!
1:35, Can't you just use the flap head screwdriver to take the other two out with the flat cut outs/grooves then use a plier or something to twist the other one one? Also thats very neat in that carb setup you can change the different jets for different situations high power gains and low end torque for example. Thats awesome, its alot more linear than a one way high performance jet, its like high performance vehicle that can't gain much more performance with their VTEC setup unless they get big profile cams and a better tune but then you can possibly lose your VTEC engagement in total since the VTEC Killer setups are meant for racing and not for street use that type of thing. I wish some automotive products had a better way to retain VTEC while getting bigger gains but oh well. Yes i know there are different cams but the moderate ones will make great for performance and on the street but not exceeding and going to race setup where idle is wonky and everything is not great on street.
Anyways hope i don't get bashed about my comments. lol Loving this motorcycle jet carb conversion setup. I can't believe its taken this long to finish work on that 4AGE. IMO, if i had a project vehicle I'd be on that every minute.
Where did you get your trumpets?
Is this same. With honda cb400sf?
Hi. Why is the air jet blocked ?
Witch air jet do you block off the one your finger was on or the middle one that your finger was pointing at ?
The one I was pointing at. But blocking off the air jet didn't work for my bike carb conversion on a 1.6 Toyota 4age engine. Made everything ridiculously rich, like 9.5:1. Things were much better with the air jet unblocked actually.
From what I understand the kit for my bike (v star 650) has different size jets and you have to get the right tune. I plan on putting in a new air intake and exhaust do you know anything about that? Idk what sizes to put in there. I've never done this before so I could be totally off
for short uni pod filters (with the vinyl end-caps) and an open exhaust with no baffles: 15% bigger on the mains and stock needles shimmed with 4 shims under each needle. stock idle jets with the mixture screws tuned for best idle quality when warm. how about that ? it should rpm like it never has before after you ditch the stock airbox with the above jetting.
Hi this is Tyrone. I own a 1997 Zx7r 750cc Kawasaki Ninja motorcycle. I made some mods upon my bike and it now is running rich. My friend tells me it's doing this because I am not in motion riding bike. So at idle he says bike will run rich until I'm in motion so air through ram air ducts mixture with fuel as I ride would thus lean out the rich issue an bike will be running fine. Is this acertion true ? It runs rich upon cold start up of bike to reach temperature. I'm planning to switch sprockets to 15t and 45t respectively. So I will have a minus 1 front and a plus 2 rear. I read some where that I need to change the jets to correct the rich issue. Do I need to have my P2 model Zx7r 750cc put on a dyno ? I took off all emissions stuff added block off plates changed the OEM coils to stick coils has 10r rear shock and 10r throttle tube. I have housing for 10r but my cables from 10r are to short dont work. The Zx7r throttle cables are somehow not fitting properly into the 2004/2005 10r throttle housing for me to use. I need help figuring it out do I need new cables ran from housing into my carbs?
Will the same process work for a 2003 Suzuki Volusia 800? I installed new Cobra exhaust and now the bike is running rich. I purchased a Sigma jet kit specifically for this bike. Are the instructions pretty easy to follow?
This process is virtually the same for any bike or vehicle with a CV carburetor. The hardest thing on many bikes is actually getting the carbs off the bike.
Did it work or did you cut the springs
what is the size of the main jet and pilot jet?
Nice 👍🏻
what is the effect of pluging the air jet? I have a aw11 with 40mm keihin cvk carbs and the car responds fine with a 180 main jet. also the air fuel ratio is great. does it have anything to do with the throttle response?
I asked six sigma about this and they told me that by blocking this air jet the mixture is enriched more. I think it plays the same role as putting in a larger jet. I will do a detailed tuning video with different jet sizes and everything so I will have some detailed info on everything. How do you like the carbs compared to stock EFI? Any other mods on the engine? Is it a 4age?
the carbs are amazing, the throttle response is instant an the car pulls way down low. But because of the carbs the car keeps pulling way op the rev range.
We managed to make the ignition and the coils from a bike work on the 4age engine, which creates a bigger spark and it sparks twice. the downside of the double spark is that the bougie last half as long, but it makes the engine with the carbs way more efficient and the engine could in theory rev up to 11000 (i obviously do not want to do that)
also one great thing about my carb setup is that i can mess with tailgaters. When im driving and i turn the key off the carbs keep sucking up air and fuel but it doesn't ignite, but it wil after i turn the key on again and al the air fuel mixture that is in the exhaust is ignited which creates a big flame and a hard bang out of my exhaust.
bart brugmans Sounds like awesome fun! Amazed that you made bike coils work with the engine
good old keybangers, never fails to keep tailgaters at bay or unsuspecting pedestrians......
Hi I have some question a jet kit was put on my Kawasaki ZR7S. My bike doesn’t go over 90 miles an hour now is there a possibility something went wrong with the process
If the jet kit is the only thing that was changed than yes, but other things could cause that issue too.
Nice
The screws you are referening too & the reason they are getting rounded off is because you are using the wrong type of screw driver. They are not a Phillips screw head they are in fact a JIS type (Japanese Industry Standard) although yes you can if carefull get away with using a Phillips screwdriver, if you own or work on a Japanese motor cycle it's work investing in a small set of JIS screwdrivers/Bits.
I Hava a NIBBI Racing Performance Carburetor 32MM Motorcycle Carburetor, would you know where the two hoses on the side of the carb leads to or where it should be connected to on my 250cc motorcycle? I know where the standard hoses, like fuel and bowl lines connect. But the hoses on the side have me at a loss.
Are they very thin? Two stroke?
@@d4a Four stroke. Not thin. Normal thickness. Same thickness as the bowl overflow hose.

Is the process much different for a v twin ..ie Honda firestorm.
Not really. Instead of 4 carbs you have 2 and that's it.
i looking at this bike i wanna 85 Kawasaki Vulcan and the gentleman selling the bike say it has a messed up jet kit and the engine is getting to much gas is that an easy fix and how does that effect the engine? ill take any help im new to this haha
What do you mean by engine is getting too much gas?
ill have to ask him in the morning becuase i have no idea honestly haha do you have any possible ideas?
Not until you explain the problem better and in more detail. Like this I don't really know what's going on. What I assume by getting too much gas is that the mixture is rich. I.e. Someone put jets that are too big in it. This will cause poor gas mileage, weak throttle response and probably a smelly exhaust. But rich is better than lean, which is too little gas, and can cause engine damage. Rich makes more carbon deposits and dilutes oil sooner but still not as dangerous as lean. I suggest you take the bike to a good mechanic as diagnosing anything through comments based on a one sentence description is anything but reliable. This is just to give you an idea about what's going on.
thank you i appreciate it !!
Amazing! What was finally your final Jets setup? Main, slow and idle needle turns out?
140 mains, stock pilot (42 I think?) 2.5 turns out.
@@d4a thanks! I really apreciate it!
@@d4a hi buddy, finally install the Jets in the Carbs according to your answer and im really happy it works Perfect no lean or rich mixtures any more, as in dont get an afr it was so hard to me to setup the carbs, i plays whit 180 170 165 160 and 155 main Jets as i read in some forums but the car runs really rich, thanks again
@@d4a 2½ turns out is what the repair manual says to start at. but for some reason my CBR600F2 doesn't want to run even halfway right unless pilot screws are almost all way in like around ½ to ¾ turns out. and i noticed one carb that tried to idle up when mix screw was all the way in. 🤔. could this mean i need a jet kit? and if so is there anything i can do with what i have to know for sure before ordering parts?
Huge inspiration to do a bike carb conversion. I just want to know if you have any problem starting your car in the morning since there's no accelerator pumps in your bike carbs.
That's not what an accelerator pumps does. Cold starts are handled by the choke.
@@d4a A buddy of mine ran a set of 40mm bike carbs on his Nissan 1400 (South Africa's Datsun 1200 with a 1400cc engine) and every morning he had to manually prime the carbs in order to start even if the choke was used.
@@d4a But those bike carbs made that little 1.4 run like hell once it's running.
Something was incorrectly setup than. Maybe pilot jets were too small. I started this car many times at - 10 Celsius on the first try with choke on.
@@d4a Thanks for the info. Keep up the great content
So this kit will make more hp? Or better throttle response?
M It will do both and more. Jet kits affect your air and fuel mixture which affects everything in your engine: power, responsiveness, mpg, risk of knock, etc.
@@d4a when you say risk of knock... do you mean a bad carb set up can cause a rod knock and damage?
If these are from a Japanese bike, those screws are JIS (Japanese Industrial standard), not Philips, people use Philips screwdrivers on them and that is what causes the damage. Always use JIS screwdrivers on Japanese bikes.
What are the two holes on top of the carb?
If we mean the same thing they are just vents.
@@d4a did u close yours or did u leave then open?
Left open. Makes no difference.
Does this make your bike faster?
Essentially yes, but doing this alone makes no sense. Jetting is usually needed along with other mods, such as a less restrictive exhaust for example.
Why you have to plug that air jet?
It further enriches the mixture
Espanish??
I fucking love your channel bro, you never fail to make it healthy and clean, I would love it if you go versatile man, make cheap builds that everyone can learn from, eBay turbo kits, eBay supercharger builds, go real cheap.. people love it, try Honda as a learning platform cause of their cheap and availability, I'm saying this cause it's a learning channel after all where we can benefit and you make money off of it.(: much love: Ali.
Crypsis I actually have a really cheap idea I might try to realise as soon as I finish the mr2.
alans will still round over time what about hex ?
nice video but pleeeease clean those carbs!! ( you have a great project car )
fantic rider Thank you. Will clean the float bowl covers I promise. Everything else is squeaky clean.
