How was the throttle response and does this carb help your bike start cold now

Throttle response is good 👍 it starts up cold just fine

That's Awesome. I started to get my son the semi auto version , but I came across a super good deal on a crf 110.

[@jerrystatic256]

Bought a Nibbi for my Tao Tao 250 tbdr7. I couldn't get it dialed in for nothing. I had some issues with the throttle slide not coming all the way down. The throttle cable had plenty of slack so it wasn't the problem. I ended having to put my stock back on.

[@ridingwithmischief]

Clarification these are air adjustments on the flange carb. No fuel adjustments can be made. Good video and informative 👍

[@MartinRacingChannel]

Fuel adjustments are from changing the jets or moving your needle clip. All depends on what your bike needs.

[@ridingwithmischief]

@MartinRacingChannel in the video you had said adjusting fuel while turning air screw. Just clarifying for anyone watching the video.

[@MartinRacingChannel]

@ridingwithmischief I should have gone a little further into detail. I meant the air to fuel ratio...The air screw turned clockwise makes the mixture richer, anticlockwise will make the mixture leaner. Thanks for watching and leaving a comment.

[@Dr.whisper]

it doesnt matter if you have a air screw or a fuel screw the do the same thing just in the opposite direction... so to clarify on your comment you would be incorrect

I have a Pentor 125cc and a Nibbi 22mm. I set it up as you showed. Everything works fine but there is bogging at the bottom. From zero trottle there is bogging. There is no bogging at higher rpm. I didn't change any nozzles.

[@martapatalan3490]

main 98 slow 32

[@Josh-ux6zz]

Lookup how to adjust the needle. That is supposed to control 1/4-3/4 throttle. Probably just needs a little more fuel. If I understand correctly. If that doesn’t help you might just try the next the next size (slow) and see how it does.

[@Cereal_Killr]

Just built a Mega moto 212 with a Tilly 212. I put a 24mm Nibbi on it and I'm loving it. Fired right up! maybe 3 pulls. Now I just gotta dial it in. Great carbs and looks second to NONE! Their filter is sick looking!

Hello brother I'm blessed to have bumped into your channel I just got my son for Christmas the x pro storm 125 cc and after putting it together notice right away the carburetor that comes with a it's not good at all can't even be adjusted please tell me exactly which carburetor I can replace it with I feel bad my poor kid wants to ride and the bike is just sitting there thank you for your help God bless you in Jesus name

[@MartinRacingChannel]

This one in the video description works great and is easy to tune and get your bike running great. For the time being check your manual it shows how to adjust your stock carburetor. It's a slow process to take the carburetor off without a swivel, but it can be adjusted and done in less than an hour. Make sure your carburetor is getting gas and make sure when cranking you're not pulling in the clutch. Let me know how it goes. Thanks for watching and God Bless you all too!

[@jorgepomales7456]

Thank you so much for your response I'll definitely let you know how it went I am going to order the carburetor today God bless

[@MartinRacingChannel]

@jorgepomales7456 Sounds good. If you want to save some money, you can get the gray version of the carburetor it's a little cheaper than the black , but it performs the same. Make sure to buy an air filter at the same time. That is in the description also. Good luck with everything. If you need help, don't be afraid to comment.

[@luisnavarro880]

Try smashing on the trottle and if it Boggs bring it to the 4th step on needle.

[@luisnavarro880]

Mixture screw bring it to where is happy then screw in 1/4 to 1/2 turn in . You are not looking for high engine noise. Rich is king. This way the pawwa is always there. They 1/8 turns at a time trust me is worth dialing it in. And is so snappy and you will know once you know you dial in the widow maker.

[@darkwriter77]

Been struggling with my Boom Vader 125-10BD and getting the stupid thing tuned right. It came from the previous owner with a VM22 clone carb already installed - slight bog on accel, not a lot of low- or mid-range power, but good top-end. Plopped on a Nibbi 26mm. Better low- and mid-range power, top-end is meh, and it bogs a LOT if you rev it quickly. Stepped down to a 24mm Nibbi, and it's only slightly better than the 26mm. Bought a bunch of extra pilot and main jets, tried all different needle and air screw settings, nothing gets any of them 100% where they need to be. No idea how the heck so many other folks have been reporting their 24mm and 26mm Nibbi carbs work great without any bog on their 125cc's.

[@MartinRacingChannel]

Me either, I was able to dial in the 24mm pretty good , but not where close to the performance of the 22mm. If you watch the other video linked in the description you can see the results there... I'll have to go back through my videos on my old phone and see what the best setting is that I found for the 24mm and let you know.

[@MartinRacingChannel]

24mm carb setting that worked best for me 110 main jet 35 pilot jet You will have to see what needle clip setting gives you the best result. I think I had it in the center. This combo gave me a perfect spark plug on wide open throttle , but there was still a very slight hesitation when twisting the throttle off idle. I was going to try a 34 pilot and 36 pilot jet and see which would fix it. The kit from Amazon only had a 32 and 38 pilot, and neither of those were better than the 35 pilot jet. Hopefully, this helps some. Let me know what you end up doing.

[@MartinRacingChannel]

@darkwriter77 Did you get it dialed in?

[@darkwriter77]

@@MartinRacingChannel Unfortunately, no. I wound up switching back to the VM22 clone and it runs pretty good. Still a bit of bog, but not terrible, and my top speed is around 60 MPH, so it's good enough, I guess. Just sucks that I now have two Nibbi carbs just laying around in boxes in the shed - waste of money. 😞

[@MartinRacingChannel]

@darkwriter77 I understand. I hate that you didn't catch my video earlier. Good luck with dialing it in.

[@jamesa6272]

Great. Now what does the plug look like. I got my 22mm nibbi dialed in. Ran amazing! Pulled the plug and it was clean which means probably lean which means no good

[@MartinRacingChannel]

My plug looks great at wide open throttle check. Just normal riding it's a little rich. You probably need to move up one jet size on the main jet. I would clean the plug or use a new one and ride how your going to ride and check it again. When I put my big bore kit in my plug looked like that and then after a few wide open pulls is started to get a chalky white tint. I was just going to move up a size on the main until it gets a light brown color.

[@jpenadelaify]

I got the same carb and I cannot get it dialed in for nothing. Black soot on the plug and exhaust so it's rich,but giving it less fuel and adjusting the idle it bogs when you slowly get on the throttle. Im stumped. Also is your choke way up I'm there with this setup? Tough as hell to choke mine

[@MartinRacingChannel]

What dirt bike?

[@jpenadelaify]

​@@MartinRacingChannelI just edited my comment above. It's a Storm 125cc

[@MartinRacingChannel]

@jpenadelaify The choke is very high. What air filter are you running? I'll be able to help more once you tell me that.

[@MartinRacingChannel]

​@jpenadelaify If you are running the nibbi filter, the bike runs a little rich. To tune it, the fuel to air needs to be screwed all the way in, start the bike, and turn the idle screw to where the bike is idling at the rpm you like. Then, start to turn the air to fuel ratio to the left in very small increment like 1/4 turns. Rev the bike each time you make an adjustment to see where the bike runs the best. Don't adjust your carb until your bike has warmed up at least 2 minutes. Make sure your choke is all the way in before you start adjusting. The bike is easier to tune with the uni air filter to me. The bike doesn't run as rich as it does with the nibbi air filter. You might need to adjust your needle for where you live I'm in Louisiana. If you can't dial it in with the needle , then you will have to drop down a size on your jets. Follow your manual pamphlet to determine if you need to go down on your pilot or your main jet. Mine burns perfect at wide open throttle, it's a little rich at idle and putting around. I ride at 1/2- wide open most of the time so the stock jetting has worked for me.

[@jpenadelaify]

@@MartinRacingChannel thanks man I'll give that a try seems like I've tried everything besides swapping jets or moving slots on the needle. I'm running the Nibbi filter with it and I'm in East Tx real close to Louisiana Line

What was your jet settings in the end? Also how many turns out was your air/fuel screw?

[@MartinRacingChannel]

I'm running the 22 mm with the factory jetting 98 main 32 pilot on the 4th needle clip. Every bike is different on the air to fuel screw. Make sure your bike warms up for 2 to 3 minutes. Turn your air to fuel screw all the way in, set your idle at the rpm you like. Begin turning the air to fuel screw to the left in 1/4 turn increments and rev the throttle each time you make an adjustment. When the bike isn't bogging and you can cleanly rev the bike you should be good to go. My bike is a little rich at idle, but great everywhere else. Spark plug looks right at Wide open throttle check.

They are fun to play on, but there is a good bit of wrenching that has to be done. Can't beat the price though. I've been working on mine today as well. I have rode the mess out of though so it's to be expected 😁

[@MartinRacingChannel]

I have a stock crf110 and was planning to run the 19mm nibbi very soon. I think if you are planning to keep your bike stock bore, the 19mm will be better. The 22mm would probably work great as well, but it may take a little longer to jet and tune correctly. I learned on the 125cc engine that a bigger carb isn't always better. My bike runs better with the 22mm than the 24mm.

Im wondering, and ive read through these comments and I haven't seen anyone with the same issue. What are the two separate fuel lines? Theres one right at the mouth of the air intake and one down on the bowl?

[@MartinRacingChannel]

The one at the bowl is for draining the bowl. You can open it with the screw below the bowl to drain the bowl before making jetting changes. The one at the mouth of the intake is from your gas tanks petcock valve. It's how your carburetor gets fuel from your tank.

[@brylanshaw2092]

@@MartinRacingChannel I guess I shouldn't say separate fuel lines because I'm not 100% that's what they are. My bike uses gravity to fuel the carb, via the fuel port at the mouth of the carb. The Nibbi carb I have has a whole line running from the bowl and I didn't know if that was a vacuum line or something? Do carburators need a vacuum line pulling fuel through it's jets?

I rebuilt the bottom end and all that. So I wanted a higher performance carb. Anyways when installing the carb I cannot get the throttle to snap back. I am using odi lock ons on protaper xr50 bars. Pe throttle cable as well. Throttle cable is long but even without it on the throttle tube it won’t snap back at all. Thank you and hope you can help

[@MartinRacingChannel]

Unscrew the red cap on top of the carburetor that the trottle cable goes through and make sure the cable is running through the spring and o ring. Once you do that before replacing the cap back on twist the throttle and make sure nothing is binding. The next step will be making sure the slide is all the way seated in the carburetor. Sometimes, it can be 180 degrees out and cause the issues you're having as well. Let me know how it goes tomorrow.

On the nibbi racing website, it says the 19mm carb is suitable for the apollo 110 and 125cc dirtbikes. However, it also says the 22mm carb is suitable for 110cc-130cc dirtbikes.
