HAWK 250 FULL NIBBI INSTALL TUTORIAL! 

Thank you

Thank you

Appreciate it bro

what aftermarket exhaust pipe did you get if u don't mind me asking

You need a larger main jet, not a CDI. You can check by looking at your spark plugs after running WOT and then killing it. Look up how to read spark plugs and you'll be looking for a lean condition if your main jet is undersized.

Sounds lean at the top needle on 4

Thanks 4 that advice. Plan on installing this on my bike

@@kev8869 Great choice.The carb is awesome for sure. I had to try a couple different jets. If I remember correctly I went with a 95 and I'm up in North Idaho. I could be mistaken about the size I stuck with, that was 800 miles ago...lol. Good Luck and Safe Riding.... while trying to kill yourself all at the same time. Or maybe that is just me.....

@@IdahoClay if you have a link for jets cool!

@@IdahoClay also does it make a difference in the year? Mines a 2015

@@kev8869 I do not believe so.

Oh yeah dude. I got nothing but great things to say about this carb. I love that just installing it is basically just an insta fix for any stock carb issues

What size jets are you running?

@@chrisMcG17 I change depending on how I feel and motorcycle feels(temp, etc), but usually keep updated on my blog: MyMotorcycleBlog.com

@@MyMotorcycleBlog looking at ur site. Just looking for an idea of jet sizes with nibbi

@@chrisMcG17 I believe I'm currently running 35 pilot and 115 main.

How did you get the carb to fit I I have a 2020 tbr7and it was to big for the space

28mm nibbi? I’m about to get a carb. For my Tao tbr7 250 and don’t wanna get the wrong one

So thats the better choice then? Was about to order the 30 and replace manifold and add air pod as in this vid. Any benefit to doing that vs going with the 28 and retaining og air box?

Yes, but you also might need a throttle cable

You can up a jet size that’s no issue. You’re right m, the stock jet may starve it at higher speeds. But there’s only so much you can do with your 239ccs. You may find a power increase with a larger jet though. The carbed models are sooo customizable. Just try it out, you’d be surprised what a little more fuel can give you

How did that go bro ?

How long yo got your bike for bredda?

well done!

there are screws (not the carb adjust screw) that allow you to adjust the fuel/air mixture. the are on the right side of the carb and they should be brass colored

Same I don’t think he did

Bolts right up 👍

Go watch a different RU-vidr like moto cheese, this guy constantly provides wrong information

I am below sea level in louisiana, i have done 0 jet changes since stock installation

What are the stock jet sizes for the PE30???

I’m at zero elevation also… have the shitty but less restrictive exhaust… so what jets? I get you’re running the stock jets but would there be a better option than the stock jets to use with the pod filter and exhaust mods…???

The stock jets on this carb are plug and play for an unmodified hawk

@@mototaco6603do you have a video on messing with the jets?

a perfect seal is necessary. even the tiniest amount of air between that intake manifold and that adapter will cause an ultra lean environment and your bike will not want to start

@@mototaco6603 good to know. I’ll go back and inspect everything I ended up putting a 28mm on it for the time being.

​@dillonwestley6138 ever get this problem fixed I'm having the same issue😅

@@toastee7556 I wound up keeping the nibbi 28 with their 38mm intake filter Stock jets, tuned a bit and then replaced the exhaust and it worked perfectly, until the motor threw a rod, probably due to oil starvation because I did not maintain that thing at all. But I also got it for only like 200 bucks.

@@toastee7556 most likely the 30 is too much air for the stock jug. Go back to the 28 and break out a flat head and start fiddling. But make sure you watch plenty of tutorials on how to tune a carb if you’re not familiar. When you blip the throttle it should rev and then go back to idle. No hangs No popping If it stays at the rev limit you had when you blip then you gotta keep tuning if it falls below idle and comes back same thing.

single counterbalanced cylinder produces most of its vibration in the head of the motorcycle ironically right where the intake manifold of where the nibbi carburetor is mounted. what happens over time and there are documented cases of this happening; is the low-thread contact of the metal belt on the hose clamps paired with the vibrations caused them to back off of each other typically in the range of something extremely small like 250-500 miles. everything might be well and good for the next couple of miles until the lubrication of the fuel air mixture paired with the NIBBI pressing against the frame of the hawk causes the carburetor itself to be pushed off of the manifold causing immediate power loss. this happened to me once before in the pine barrens and I realized it was the hose clamps coming loose and allowing the rubber intake adapter to fail. having no tools on me at the time, I had to screw the hose clamps back on with my credit card. high vibrations and the nature of the dual sport motorcycles off-road environments don't exactly make this a possibility- they make this an inevitability. so the question is; in the imperfect science of the aftermarket world. what do we do? you could over-tighten the hose clamps. but this causes the adapter to SQUEEZE itself off of the intake manifold over time. bending the residual metal of the leftover thread belt of the hose clamp into the flathead screwdriver recesses of the hose clamp screws is a non-destructive method of preventing this issue. there are other ways as well. there's threadlock putty.. or like many diesel mechanics, you can lockwire the tops closed with some high tensile safety wire essentially rendering every other option less effective. i have since lock wired my hose clamps. however for a simple carb install video i didn't want to begin a lesson on safety wiring- and wire twisting pliers may not be a part of every vice-grip mechanics repertoire. though since its a relatively old video, it may be time for an update

Ive heard of it. Is there a reliable source you can give me? Id greatly appreciate it 😁👍

I was wondering this as well lol. I came here in hopes of some validation. No luck. What did you decide to do. I’m guessing it’s an egr or something? The line going to the carb might just be so it can burn the exhaust gas. Thought about just replacing it with a catch can and eliminating the current setup.

@Josh-ux6zz I ended up not using the nibbi at all because I couldn't get it to fit in there, and I didn't know what to do with those lines. Instead, I just dialed in the carburetor it came with with the jet kit. After a lot of trial and error, I finally got it to where it runs a lot better than stock. It has a lot more power and isn't backfiring nearly as much. I'm still using it as my primary transportation in the warmer months, and it's been great.

Cut it off.

Cut it

i have the same exact problem, i ended up rolling the hose up and zip tied it to the frame for the time being, i have 2024 hawk X 250, not to mention i cant get this nibbi tuned no matter what i try it still boggs at half throttle im ready to throw the stock carb back on if i cant figure this crap out tried everything and every size jet etc

better consumption and better hp mine increased by like 2-3 hp

Same engine, there should be 0 problem

appreciate it bro

Not at all, just installed it with its stock jets and took off

@@mototaco6603 did you have any issues or end up lean or rich after say few months of riding ?

@@nassiratti8542 for me it was an entire plug and play fix for both of my hawks. I play with the idle screw every now and then but thats common. The nibbi is probably the best upgrade you can put on your hawk with little to zero tuning

@@mototaco6603 gotcha thanks !!

As a matter of fact I put a nibbi on my friends X pro titan, can confirm it works. It’s just a little more difficult to mount. But yes 100%

@@mototaco6603 I was just asking because I'm thinking about getting the titan what are your thoughts and experiences with Chinese dirt bikes?

That's a carb bowl drain tube nothing to worry about.

@@FishWithWyoming Yeah. I got it figured out a while ago.

Extra, the stock jet is perfect for the stock bore

Oh and my gearing is 15/39

17t front 45 rear should bring your top speed up and reduce RPMs in higher gear

the one that connects to your airbox? yes it should. the cold air intake is not a necessary purchase to fit the NIBBI to your bike

Did you ever buy a hawk?

its well documented the NIBBI carburetor brings out more potential in the hawk 250. to achieve the hawks pricepoint, some quality assurance cutbacks had to be made. one is the stock carburetor. its simply not the best. so some people opt for the aftermarket option

the choke is the little black hex 'screw' on the other side of the nibbi carb

I got a 30mm nibbi and mine cuts out at 3/4 throttle still playing with it it came with a 128 main jet in it I put the smallest in that it came with but I still doesn’t run right unless I take the air filter off then it runs fine. I think a 115 main jet is what I want just waiting on the extra jets to come.

eh. yes lol. would have to be quite the epic wipeout though. then i can do a rebuild video

In this video yes

Ever figure it out i got the same problem?

clockwise is less fuel counter clockwise is more fuel

Absolutely

@@mototaco6603 How many rounds?

30mm works for the brozz

@@mototaco6603 Good to know, thanks! I just might have to experiment with a 30mm.

do you have a link to this carb? i know what you mean about the flange i'd just like to see the model

Nowhere it’s a vent/drain line

they really open the bike up, id say 5-8 MPH more. and yes the tao tao takes this carb too

yeah exactly, the cold air intake is basically acting as the filter. its washable and reusable too. if you want to do more muddy off roading then you can always reinstall the airbox aswell or put a box around the cold air intake

Thanks, any idea where I could get some plastic covers for the bike?

So what did you do with the breather tube that connect from old air box to engine?

@@scottyguinn203 I'm curious about that airbox as well! when you cut the tube from it did you cover the hole to the airbox that is no longer being used?

@@yikez317 I from crankcase got clear tubing, ran it up next to air box w a mini pod filter on it ... Then used plastic bag w rubber bands in air box tiny hole so it's blocked, if mini pod issue arises I'll just route tubing over chain as is n use the kick back oil to go in chain ... The air box plug is over chain also so if it kicks oil back u just let a drip.

yes

the hawk 250 mods will fit the raven

please help

nothing its just a drain line

Yes i have a video on it, completely safe

@@mototaco6603 okay, also would a pe28 fit on the 250?

the air filter should last a while before it needs replacing

@@mototaco6603 is it work on Aprilia Sr 150?
