I installed the Nibbi PE28FL on my Hawk 250 this morning. On my Hawk, the factory studs weren't long enough to use the spacer and both gaskets. I just used one gasket without the spacer and bolted it directly to the factory intake. The factory nuts went on, no problem. I installed a 38 pilot and 120 main jet. I am at sea level. I am happy with the improvement over the factory carb. The only adjustment that I made on the carb was to the idle. I also adjusted the throttle cable to give it a little more "slack." It starts very easily now. Just barely touch the start button and it starts right up! For now, I am still using the factory hose and airbox. First impression wasn't amazing because I was only able to ride it about 3 miles before the rain came this morning. I took it out again this afternoon after the roads dried and it was a big improvement. Well worth the $72.99 and a few minutes of my time. The only issue that I see is that the throttle cable has to take a sharp bend at the gas tank. Not causing a problem right now but it might be an issue in the future.
Very happy to hear it worked out for you & your feedback with new flange style Nibbi carb will definitely be appreciated when it comes time for people to make the decision wether to buy one or not so thank you for sharing!!
I wasn't able to do the paper, plastic, paper thing either because of the lack of bolt length coming from the intake manifold. I ended up using the stock plastic gasket because it had a paper(ish) side and a plastic side. The plastic gasket that came with the Nibbi was shinny plastic on both sides. I put the paper(ish) side of the stock plastic gasket against the manifold and the shinny part against the paper gasket that came with the Nibbi, then the other side of the paper against the carb. Does that sound like my best bet or would y'all suggest otherwise?
I have no idea. It was more than a year ago and I haven't even thought about it since I installed it. It just works. I don't think I changed the needle position from the factory setting. I wish that I could be more help.@@trentminto4985
I installed one of these on a X pro Templar 250. I would highly recommend buying some extra gas line and good American made steel hose clamps installing your fuel lines on the carburetor before you ever try to put it on. Trust me this will save you inventing new curse words and possibly an hour out of your life.
I'm running this carburetor on my TBR7D with a cold in air intake deleted cat I did vows and it runs great I'm running a 115 main jet, running a 17 to 40 sprocket combination I can do about 65 on flat. Looking for recommendations for more power
I just put a 28 nibbi on my tbr7. And when I got to give it throttle it cuts out. I have an exhaust and running a stock air box. I’m running a 115 main and a 48 pilot. When I had a 112 and 40 it ran worse. Any idea what way I need to go? It will idle fine and I can baby it and give it throttle but when I hammer it it’ll cut out and die?? And I’m around 900 ft above sea level
I ordered the sigma 6 stage 1. 2. And 3 jet kit for my stock carb and it had pilot jets and main jets . I changed them and it does great it came with main jets pilot jets and several different sizes and several needle shims. But my bike isn't as modded out as yours so it didn't need a whole lot of extra help
The issue isn’t really that if you jet the stock carb the bike won’t appear to run correctly it’s more so that the factory carbs only a 25mm carb so it’s not really an optimal size for the engine using a good quality 28mm nets you more power better throttle response etc etc…how my bikes setup with out performance parts big bore kit so it’s a true 250 high flow high comp head cam etc etc a real 30mm is ideal at that point but a stock or internally stock bike line this with bolt ons a 28 is a perfect combination
@@Jboost412 yeah all I was saying is the stock carb does awesome with the right kit for a basically stock bike . O just wanted to try in before I upgraded the carb and it couldn't run any better with any other carb until I do more to the bike and it requires more
Absolutely I get it…it just seems there’s allot of confusion when I tell someone buy a 28mm carb they typically say “I already have a 30mm” not realizing it’s just a 25mm clone carb but certainly they’ll run fine jetted correctly
@@Jboost412 now when I do more still to the bike I may need to go bigger . It may say somewhere but I'm just gonna ask you since I have you here . Where did you get the big bore kit
I actually custom turn the big bore kits for these bikes as well as sell ported decked heads in on Facebook in all the China bike groups under the same name if you’d ever like to get one just let me know
Im buying this setup for tbr7. The stock rubber air intake is so suspect and i think that was giving me more problems than even the carb. I got some friends that want to ride this year and with my 17-43 and this carb, i should be able to ride along with a R 1250 GS. Not bad for a couple grand.
Setup correctly they’re a really reliable fun bike that can do highway speeds with a little work if you need any help setting it up definitely don’t hesitate to ask!!
@@Jboost412 im just so confused how to make it better. I know most of the science now but what do you recommend for pilot and main jet sizes. Im about sea level, and have new ignition coil and spark plug plus this new nibbi carb. So frustrating because i dont know how to explain what im hearing. Hopefully you can give me a better starting point. Thanks
Hey Jay thanks again. I took ur advice n got this carb I love the look n performance. Now I need a little more help. I believe the carb came with 115 main jet n I'm at 774 elevation, do I go up to a 120 or down to a 110?
Hey Jay I really need advice. I just bought the latest bashan brozz 250 recon n I want to upgrade. is the nibbi better than the Amazon mikuni? If so, the one in this video is the one I should get?
Nice buy! They’re a solid bike! And absolutely the clone carbs are garbage 25mm carbs so never wanna use them!! A Nibbis a really good carb the new pe28FL is a nice direct fit just jet it & install your ready to adjust the air fuel & enjoy good throttle response and power! Make sure the valves get adjusted also since it’s a new bike…have a video on how to do it the right way they always need adjustment in the beginning if not the valves can’t close all the way with no lash so definitely get them setup as well!!
Yes sir definitely a nice bolt on carb there I have no complaints the quality was good exactly what i expect from Nibbi from previous carbs we used & still use today I’ve never had any issues with a Nibbi so far so I definitely recommend them to everyone
Where did you get the gasket/spacer at? When to put this on and the bolts go through and hit on the inside to where I wouldn’t be able to tighten all the way
Question and help needed. Installed a nibbi 28 on a tt250. Cable is installed properly. I dont have enough slack for slide to seat. When i first fired up reved to 7k adjust cable as much as i could and got it down to 4k at idle. Cable lengtt is good but not enough slack for the nibbi. Any ideas on another cable with more slack?
Thanks again for the video! Perfect for a stock engine, flange connection and all. Just ordered one for my Hawk (already have the jet kit on hand). I am not sure why the so called Chinese Keihin pz30 clone or Mikuni VM26 clone are even remotely called "clones". They are clearly not clones and clearly a smaller carb internally. God knows what design they are really cloned from and are really just garbage. Agree with you. Buy one these Nibbi's and throw those cheap Chinese imposter pho-clone carbs in the trash where they belong.
I truly couldn’t agree more Makes it really confusing when someone asks me what size carb I use “30mm” and they respond with “well no reason to upgrade it comes with a 30mm” 🤦♂️ I always have to let them know it has a 25mm carb that’s confused so it calls itself a 30 😆
@@4150CHF It is the best carb I have had so far as far as power and drive-ability. The Mikuni VM26 clones are a waist of time and money after trying them. They do not even resemble an actual Mikuni VM26 and are really a generic 26mm carb with a 30mm throttle plate. A genuine Mikuni VM26 is completely different and actually has a 30mm venturi. Nibbi's are a quality carb.
I just got the New PE30 and that little plastic piece inside the bowl that goes over the main and pilot, I can just take that out right and it won't cause any problems with air or fuel flow through the carburetor cause I just rather take mine out before I put it on my bike so I don't have to worry later..please let me know
I was about to purchase a Nibbi PE28FL for my new Hawk 250 but after reading the comments below, something doesn't seem right. I don't even see this many complaints about problems from people using the $25 Mikuni clones sold on Amazon.
Honestly it was never the carburetor that was at fault I mean no offense to anyone since we all learn at point but your dealing with people that have otherwise never touched a engine have little to no knowledge of how a carburetor works….so with that said i highly recommend nibbi carburetors I’ve used them on allot of different setups with zero issues short or long term
@@Jboost412 OK. Maybe I will get one. I am at sea level with a completely stock Hawk 250. Most of my driving will be at less than 200' above sea level. Can you give me a link to a set of jets for the Nibbi PE28FL.
My 2021 TBR7 looks like it already has a gasket and plastic on it. I tried to put the extra gasket, plastic, gasket that came with it but there wasn't enough bolt so I'm ending up just using one of the two gaskets that came with the pe28fl. Which side of the gasket goes against the carb and which side goes against the plastic? There's a smooth side and a rough one.
off hand I believe the plastic spacer is thinner on the bottom or top so when you go to install it having it the wrong way makes it sit crooked/funny on the intake is an easy way to describe it
Thanks for that Jaysso. I didn't notice one side was wider than the other. The gaskets that come with the pe28fl have a shinny, smooth side and a rough, course side. Do you know which side should go against the carb and which side should goes against the plastic spacer?
No worries then!! honestly that’s odd your intake studs must be shorter then most considering there’s low to no quality control on these bikes doesn’t surprise me though but typically the studs are too long without the spacer so they end up hitting the carb body and it won’t Sit flush on the intake but if yours is flush then that’s all that matters!!
Yeah I get allot of complaints in our groups on Facebook about people not being able to get the Nibbi intake to fit correctly…never had that issue personally but it removed the problem all together now it just bolts right to the factory intake making it a no brainer to Ditch the janky 25mm clone carbs that day they’re 30mm’s Lmfao that Also makes things confusing when I’ll tell someone buy a 28 or 30mm & hear a response like “I already have a 30mm” well ya don’t 🤦♂️
No sir you’ll still need to adjust your needle jet for optimal operation between 25-75% throttle the red knob is just adjusting your idle speed like most carbs do
I honestly don’t understand what black knob? The carb only has 2 adjustments a red idle adjustment & a small brass screw for the air fuel pertaining to the idle circuit/ 0-25% operation after which the needle jet picks up & runs it to 75% operation before finally the main jet takes affect from 75-100% throttle maybe I’m just not understanding exactly what you mean
@@Jboost412 bro it’s a throttle valve adjustment it’s clear as day lol, I’m waiting on the same carb now. But the knob you referred to that they stuck on that gets in the way of the bolt
If the plastic spacer is used it’s definitely recommend to use a gasket on each side but I’m sure you could try it with 1 and see if it’s sealed up correctly an easy way to see if the seals 100% or not is to start it up then spray some carb and choke or similar on the area in question of it causes the Rpms to raise or lower then there’s a leak after a while the gaskets are worn so we use/recommend rtv high heat gasket maker if yours are missing you can always just the gasket maker now it works great
Hey absolutely if you have any questions about jetting or need a idea of where your baseline to start with jetting should be just let me know!! Also your throttle cable adjuster is right where the cable meets the throttle housing typically covered up by a little rubber boot slide it back loosen the lock nut & loosen the adjuster around 2 turns then lock the nut back down to make sure you have enough cable length/free play so the throttle valve “slide” can seat all the way down so there’s no issues with high idle!! I’ll be here if there’s anything you need!!
When you buy the FL version the gaskets & the plastic spacer you may/may not need should be in the box if it’s not someone already bought that carb took them & returned it unfortunately
My throttle cable is now hitting my gas tank, and my bike revs up when I turn the handlebars right. Also struggling with what jet sizes to go with. Also need help with my air mixture screw and idle screw settings.sorry I’m new to mechanical stuff have pretty good theoretical knowledge but it only got me half way with the bike and I just don’t wanna blow it up😅
@@loganhenson9052 This video will tell you all you need to know about how to tune a carb. watch?v=rCo6dJAxi64&list=PLMDEXGL1YWf11Njbv09pixUoQC7z9130G&index=2
Absolutely I’ve made allot of changes internally to the engine since the last review along with fitting it with a high travel rear shock to match my front forks 10-12” travel so it’s definitely due for an update on what’s been done & what’s to come in working on machining a new 1-5 gearbox ratio now & hopefully fitting a 6th gear as well next time I split the case I’ll know for sure if the 6th can fit but about a week I’ll get an update video now that I’m back at my shop I was out for a month dealing with some immediate family issues so I haven’t been catching my messages like I usually do but look out for an update soon!!
They both have they’re advantages there I like my flat slide for more instant power on takeoff while the PE “round slide” will generally perform better on the top end so I have one of each depending on what I’m doing or where I’m riding 😎
Ever time I put my pe28 on my hawk 250 the idle is sky high like the engine is about to blow! Install the regular carb she runs normal. I even put a 19mm from a 125 on and it ran and started fine. What am I doing wrong. I’ve installed nibbie carbs on a lot of bikes and never once had this problem. Any help is greatly appreciate.
Possibly just a defective carb or some issue with the carb that needs fixed because a 28 or 30mm shouldn’t be any issue at all jetted & adjusted correctly I’ve built allot of these bikes now & that’s our go to carbs so sounds like an isolated issue with that carb only from what I hear here
Most people who have an issue with high rpm idle and the idle adjustment doesn’t lower the idle need to adjust the cable slack at the throttle housing your case was different but general rule of thumb is if the air fuel for the pilot circuit needs to be in more then 1 turn the pilots flow rate needs to be lowered if the A/F has to be out more then 2/2 1/4 turns out the pilot needs to be increased in flow rate just so you guys know that’s pretty standard across the board from keihin Mikuni service manuals for example but good luck guys hope you all get your bikes dialed in!!
Yeah I’ve been doing allot of high flow head work lately to go along with my big bore kits I sell for the bikes cams etc etc after the work I offer these bikes really wake up & go….definitely upsets big name Japanese bikes when they get beat in the trails then find out it starts as a China crate bike 😆
Wtf is going on with mine? 2019 hawk nibbi 28mm fl but it has an oring instead of gasket material and the throttle fitment against the tank well could be better and also the stock intake tube doesn't fit over the flange in the carb
Did you rejet & adjust the Nibbi to match up with your application? Elevation & engine size modification etc etc will all affect the requirements for jetting the check the air fuel mixture screw sometimes they’re turned all the way in or out when they’re new so it’s just gonna be quick jetting & tuning of the new carb to get everything going good for you!!
Got ya so that sounds like the throttle valve or slide as it’s more commonly referred to the slide has 2 grooves on it when it slips into the carb it can fit either way but one grove is all the way and one is only at the base about a 1/4 way up for the idle adjustment to move it remove the threaded cap and rotate the slide 180 degrees so it can fall all the way down into the carburetor instead of being stuck at the top mimicking wide open throttle it’s a common issue I find in my groups I run on Facebook so no worries it’s just a learning curve & a easy fix!! Let me know how it works out!!
@@fettieteam2333 I eye balled my cylinder intake it's about 25mm ..but my aftermarket intake is 30mm...so a port match is required... Check it's to see if your carb and cylinder match...
Your average Tbr7 hawk raven etc comes with a “pz30” that well has zero quality control they basically either work or they don’t 🤨 with that said I’ve never understood why they’re called a pz30 as that would indicate it’s a 30mm carburetor 🤔 most of the factory air intakes & cylinder heads for a CG have a internal diameter around 29mm’s which makes them a perfect candidate to run a 28mm carburetor while some myself included used a true 30mm with a internally stock engine for a bit to do some testing a 28mm is a perfect combo for the CG it’s a very popular modification in most cases the 1st actual upgrade chosen “toss up between the carb or an exhaust” hard to say for sure but it definitely makes the bike respond better!!
I’ve found most of the factory heads intake sides & intakes to be 29-29.2ish mm’s when i remember to check before just getting straight to the point with my port work…as most of the time I forget or am in a rush to get one started/finished & back to said customer
If you choose to buy a pe30 the air box can be used you’ll just need to make a new air intake tube with radiator hose or something similar & run a different intake so the flange version is more user friendly for most situations!!
Thanks , about to order the pe28FL right now !!, took my bike on the first real ride and Boggs like crazy like its governor or low rev limiter 😂 also running the lridium ngk spark plug
Absolutely anytime that’s what I’m here for!! Get yourself the carb & jet kit so you have the available sizes needed…They include 2-4 random size jets also adjust your valve lash it if you haven’t already!! I have a video covering the lash adjustment really easy & really beneficial!!

Yeah I get allot of complaints in our groups on Facebook about people not being able to get the Nibbi intake to fit correctly…never had that issue personally but it removed the problem all together now it just bolts right to the factory intake making it a no brainer to Ditch the janky 25mm clone carbs that day they’re 30mm’s Lmfao that Also makes things confusing when I’ll tell someone buy a 28 or 30mm & hear a response like “I already have a 30mm” well ya don’t 🤦♂️
Yes sir this is for me!
Can’t click the links, just a heads up
Does it bolt right up to the TBR7 intake manifold or do I need a Nibbi adjustment manifold?
Yes sir the pe28FL bolts right up nothing needed but a carb & I recommend a jet kit if you don’t have one already
Thanks Jay
Absolutely!!
I just bought a used 2021 csc tt250 I want to put this carb in what jets would you recommend ?
I live in cali stock bike
So the black throttle valve knob adjust the slide? (Throttle body) . So there will no need to remove the needle and adjust the clip?
No sir you’ll still need to adjust your needle jet for optimal operation between 25-75% throttle the red knob is just adjusting your idle speed like most carbs do
@@Jboost412 the black knob is for ?
I honestly don’t understand what black knob? The carb only has 2 adjustments a red idle adjustment & a small brass screw for the air fuel pertaining to the idle circuit/ 0-25% operation after which the needle jet picks up & runs it to 75% operation before finally the main jet takes affect from 75-100% throttle maybe I’m just not understanding exactly what you mean
@@Jboost412 bro it’s a throttle valve adjustment it’s clear as day lol, I’m waiting on the same carb now. But the knob you referred to that they stuck on that gets in the way of the bolt
That’s the choke
Is this carburetor better than the mikuni Cline china version?
Do you need two gaskets with the spacer or could you just use a thicker gasket?
If the plastic spacer is used it’s definitely recommend to use a gasket on each side but I’m sure you could try it with 1 and see if it’s sealed up correctly an easy way to see if the seals 100% or not is to start it up then spray some carb and choke or similar on the area in question of it causes the Rpms to raise or lower then there’s a leak after a while the gaskets are worn so we use/recommend rtv high heat gasket maker if yours are missing you can always just the gasket maker now it works great
@@Jboost412 does the carb come with the spacer and gaskets? If not do you have a link?
Yes it should have the gaskets & spacer included when purchased new
@@Jboost412 right on, ordered and should be here Saturday. Thanks and have a great time on vacation my dude.
Hey absolutely if you have any questions about jetting or need a idea of where your baseline to start with jetting should be just let me know!! Also your throttle cable adjuster is right where the cable meets the throttle housing typically covered up by a little rubber boot slide it back loosen the lock nut & loosen the adjuster around 2 turns then lock the nut back down to make sure you have enough cable length/free play so the throttle valve “slide” can seat all the way down so there’s no issues with high idle!! I’ll be here if there’s anything you need!!
Where did you get your carb gaskets?
When you buy the FL version the gaskets & the plastic spacer you may/may not need should be in the box if it’s not someone already bought that carb took them & returned it unfortunately
@@Jboost412 Thanks, hopefully it'll be untouched
Absolutely hope so/should be if not send it back 😂
My throttle cable is now hitting my gas tank, and my bike revs up when I turn the handlebars right. Also struggling with what jet sizes to go with. Also need help with my air mixture screw and idle screw settings.sorry I’m new to mechanical stuff have pretty good theoretical knowledge but it only got me half way with the bike and I just don’t wanna blow it up😅
Ps I have a hawk 250 but same thing with same carb.
@@loganhenson9052 This video will tell you all you need to know about how to tune a carb. watch?v=rCo6dJAxi64&list=PLMDEXGL1YWf11Njbv09pixUoQC7z9130G&index=2
What is the black tube on the carb next to the idle adjustment knob?
That’s just you basic vent / overflow tube on the side of the carb
We need another full bike update!
Absolutely I’ve made allot of changes internally to the engine since the last review along with fitting it with a high travel rear shock to match my front forks 10-12” travel so it’s definitely due for an update on what’s been done & what’s to come in working on machining a new 1-5 gearbox ratio now & hopefully fitting a 6th gear as well next time I split the case I’ll know for sure if the 6th can fit but about a week I’ll get an update video now that I’m back at my shop I was out for a month dealing with some immediate family issues so I haven’t been catching my messages like I usually do but look out for an update soon!!
Hey man I’m interested in some hawk performance parts what’s best way to get ahold of you
Absolutely sounds good! The Best way is Facebook under the same name I’m in all the China bike groups so pretty easy to find me
HELL YEAA.... SEE IF IT AS GOOD AS THE FLAT SLIDE
They both have they’re advantages there I like my flat slide for more instant power on takeoff while the PE “round slide” will generally perform better on the top end so I have one of each depending on what I’m doing or where I’m riding 😎
Ever time I put my pe28 on my hawk 250 the idle is sky high like the engine is about to blow! Install the regular carb she runs normal. I even put a 19mm from a 125 on and it ran and started fine. What am I doing wrong. I’ve installed nibbie carbs on a lot of bikes and never once had this problem. Any help is greatly appreciate.
Possibly just a defective carb or some issue with the carb that needs fixed because a 28 or 30mm shouldn’t be any issue at all jetted & adjusted correctly I’ve built allot of these bikes now & that’s our go to carbs so sounds like an isolated issue with that carb only from what I hear here
Having the same problem....it even burned the spark plug...replaced it and it starts but sounds like crap I have to shut it off that's how bad it is
@@CarlosLopez-gj3pe turn your air screw in until it idles down
Most people who have an issue with high rpm idle and the idle adjustment doesn’t lower the idle need to adjust the cable slack at the throttle housing your case was different but general rule of thumb is if the air fuel for the pilot circuit needs to be in more then 1 turn the pilots flow rate needs to be lowered if the A/F has to be out more then 2/2 1/4 turns out the pilot needs to be increased in flow rate just so you guys know that’s pretty standard across the board from keihin Mikuni service manuals for example but good luck guys hope you all get your bikes dialed in!!
i just installed mine... no port or polish.. (head) but im sure my clone Keihin pwk 30 will do the bike justice.... let er rip
Yeah I’ve been doing allot of high flow head work lately to go along with my big bore kits I sell for the bikes cams etc etc after the work I offer these bikes really wake up & go….definitely upsets big name Japanese bikes when they get beat in the trails then find out it starts as a China crate bike 😆
Hi i was wondering what carb do i need for a tbr7 250 by tao tao can you help me
Wtf is going on with mine? 2019 hawk nibbi 28mm fl but it has an oring instead of gasket material and the throttle fitment against the tank well could be better and also the stock intake tube doesn't fit over the flange in the carb
I just installed a new nibbi 26, and now the bike won't start, it cranks but won't start. With the stock carb, it starts right away.
Did you rejet & adjust the Nibbi to match up with your application? Elevation & engine size modification etc etc will all affect the requirements for jetting the check the air fuel mixture screw sometimes they’re turned all the way in or out when they’re new so it’s just gonna be quick jetting & tuning of the new carb to get everything going good for you!!
@@Jboost412 It starts now. The problem everytime it starts, the bike runs on full rpm.
Got ya so that sounds like the throttle valve or slide as it’s more commonly referred to the slide has 2 grooves on it when it slips into the carb it can fit either way but one grove is all the way and one is only at the base about a 1/4 way up for the idle adjustment to move it remove the threaded cap and rotate the slide 180 degrees so it can fall all the way down into the carburetor instead of being stuck at the top mimicking wide open throttle it’s a common issue I find in my groups I run on Facebook so no worries it’s just a learning curve & a easy fix!! Let me know how it works out!!
Did you get it working?
@@Jboost412 what is the black tube coming off the carb next to the idle adjustment knob?
My nibbi carb came with an O-ring style gasket. Does that mean I can just screw them together without gasket-spacer-gasket in between?
Wish I'd gotten here soon enough. I have o-ring style as well. Your assumption is correct just be sure to lubricate the o-ring before install.
where did you get the gasket
The new pe28fl come with oring gaskets now built in. I dont like the idea of reusing those cardboard gaskets and stacking shit
That one was new i ordered it 3 days before the video…I didn’t expect to find the flange area without a o ring so the one you have does have one?
pz30 is a 22mm bore carb .... venturi cuts off air at full throttle
So this pe28 is to big? Is the pz a 22mm carb?
@@fettieteam2333 I eye balled my cylinder intake it's about 25mm ..but my aftermarket intake is 30mm...so a port match is required... Check it's to see if your carb and cylinder match...
Your average Tbr7 hawk raven etc comes with a “pz30” that well has zero quality control they basically either work or they don’t 🤨 with that said I’ve never understood why they’re called a pz30 as that would indicate it’s a 30mm carburetor 🤔 most of the factory air intakes & cylinder heads for a CG have a internal diameter around 29mm’s which makes them a perfect candidate to run a 28mm carburetor while some myself included used a true 30mm with a internally stock engine for a bit to do some testing a 28mm is a perfect combo for the CG it’s a very popular modification in most cases the 1st actual upgrade chosen “toss up between the carb or an exhaust” hard to say for sure but it definitely makes the bike respond better!!
I’ve found most of the factory heads intake sides & intakes to be 29-29.2ish mm’s when i remember to check before just getting straight to the point with my port work…as most of the time I forget or am in a rush to get one started/finished & back to said customer
You able to run the stock air box??
Absolutely brother if you use a pe28FL you can use the factory intake & air box
If you choose to buy a pe30 the air box can be used you’ll just need to make a new air intake tube with radiator hose or something similar & run a different intake so the flange version is more user friendly for most situations!!
Thanks , about to order the pe28FL right now !!, took my bike on the first real ride and Boggs like crazy like its governor or low rev limiter 😂 also running the lridium ngk spark plug
Absolutely anytime that’s what I’m here for!! Get yourself the carb & jet kit so you have the available sizes needed…They include 2-4 random size jets also adjust your valve lash it if you haven’t already!! I have a video covering the lash adjustment really easy & really beneficial!!
Does the spacer come with it?
Yeah it’s included
The stock intake is junk, it goes bad, replace with solid metal intake suggested
Where did you get the adapter?
No adapter needed for this one muh dude. It bolts right on. Put one on my bike yesterday and it makes a world of difference.
Doesn’t fit on the hawk 125
