Nice 230 sir! Coming from someone who spent almost 10 grand on a eurotrash enduro bike a few years ago, more and more I look at these simple yet undeniably fun play bikes thinking I would have been better off while having money left over to mod the hell out of it. Your bike looks good too. Always been a Honda fan.
@Palms i bought a 701 recently. Get it. You wont regret it
gotta say man, this was a big inspiration for my build, ended up with a fully self ported and polished head, +2mm lift and duration cam, roller rockers, bbr valve springs, valve lapping, milled the head down, weisco 11:1 stock bore, 4k-12k rpm selectable cdi, oil cooler and more im sure I'm forgetting.
Sounds like it’s gonna be a blast. I had a hard time sourcing parts back when I built mine. Couldn’t find any reputable options for cams and springs that wasn’t $800
@@garbinsgarage kinda had the same issues but ended up finding an alibaba express one that was crf230 purpose built and claimed +2 mm for under $50 and the roller rockers where under $25 and actually the bbr valve springs costed about the same as roller rockers and cam combined. only down side was can and rockers where China shipped.
Kick ass sound , well done 👍🏼
I have a 2019 crf230f and they are so good. Yours is very nice w the mods, cheers mate. I use mine for enduro and it rocks
Valve train is going to be at it's limits if it's a 2valve. But he's done all the correct headwork
Awesome bike bro! I race a TTR 230 that I'm getting ready to bore it out and hopefully push 26 HP as well!
I just removed the smog stuff from my 230M, that made a difference! I'm looking to do a big bore kit or something in the near future.
Spartan375x, you can find a complete kit by athen for the 230 that brings is up to a 240cc but is a little on the $$$ side. I did a hone and used a high compression stock sized piston
@@garbinsgarage Do you have any links to that big bore or high compression piston?
Spartan375x www.ebay.com/itm/07-15-Honda-CRF230F-CRF-230F-67mm-233cc-Athena-Big-Bore-Cylinder-Piston-Top-Kit-/192898315821- this is to the Athena kit which in great not quite worth the money, I would by a slightly larger high compression piston like 66-67mm and have a shop bore out your old cylinder all that should be about $180
I like your headlight mod. Coincidently I have the same exact set up for a dual sport conversion
I eventually went to a full high/low enduro with a Jeep fog light style kinda of light. I wrecked it once and broke the light bar
Bro that weisco piston makes that thing sound like a legit race bike, also got the same exhaust
Kinda does especially at idle
Engines only 250kit 11.5:1 compression only makes 23.5 hp( just the big bore and compression) no way ur stock bore 11:1 with carb, air box mods, and exhaust gonna add 7hp. A high end full exhaust will only add 1hp.
U might have 20-21hp what ur feeling is the torque from the high compression.
I had a new XR 250 and it was about 19 Hp maybe 20.5 uncorked and all free mods done.
That’s great
She's a beauty!!! Well done..
Dude... you rock. Excellent work keep it up!!!!
Switch your sprockets out youll get better acceleration and is way worth it on a dirt bike, Ive got an old '83 XR200R with a later motor big bored and cam job etc, doesnt sound much different to your crf here and I used a 11T front sprocket, havnt got times yet but it shifts, Ive also got a FTR223 engine with an ATHENA 240 kit and BBR cam engine I got for my XL185 as a donor engine but I may use it in my '81 XR200R due to lack of a local engineer for a modified engine build I had planned.... awesome bike kid ! ✌🏻
The only thing is with dirt bikes is, they are geared pretty low to start with. If you go to a lower ratio sprocket, you’ll get more acceleration but it will lower your top speed and make the gears really close. On a dirtbike, I would actually go up on your ratio so make the back one smaller by a few teeth. Give you more to end. I did that to my 230. I have a 49 tooth and I went to a 42
@@garbinsgarage depends what your looking for isn't it,
Dam it’s nice as hell bro I just got one
Wish there was a video on here doing the head ...looking to throw a big bore kit on mine and never tore into a bike ..just cars
It’s very very simple. Single cam and a tensioner next to the carb. Timing mark plug in the flywheel cover as well
instant sub
I have one of these bikes… Do they have a rev limiter from the shop?
Yes sir. The rev limiter is the video is the factory one at 9800 rpm
I have a 2019 Honda 230 and mine does 0-100 in 8 seconds and maxes out at 115km stock
Killer build! Where did you buy the carb? What model and brand is it? Thank you!
look in the discription it says it
Does it run hot or does the bigger carb (rich air to fuel) help cool it down
Hasn’t overheated on me at all and I’ve beat the crap out of it at 7000+ for 30+ min. I jetted the carb correctly so it’s not Rich or lean. But it is pumping more air and fuel through the engine for sure
What’s you do to the front suspension? Did you take off the covers from the forks?
Yes the covers unscrew and pop off but you have to have the bike on a Stand or the springs will fall out. I put a 2in pvc spacer on top of the spring to get it preload and 15w fork oil
@@garbinsgarage thanks, I appreciate it
Do you have a link for the carb kit. Can find one with the throttle
arturo munoz I have another video up if you want to check it out. It has the link. It’s video of the carb review
is high comp setup has noisier engine? what fuel octane rating are you using?
MunsKi it is a little bit louder. Has an idle sound more like a race bike. And I run 93 or 91 octane. With about 11.5.1 compression it’s ok on pump gas
Do you have a link to where you got the carburetor from? I would like to do this mod to my bike.
did you change the camshaft or you run the stock cam?
Gabriel Manseau, no I wanted to keep it fast yet reliable. It does add more power with a different cam but more heat and stress on other components
This thing flys 😂😂😂
Your electric starter can handle high compression?
Does that carb Not use the 2 throttle cables, in other words more like most dirt bike carbs? Had a 150 & the carb so much easier to work on. How much $$ does that carb go for?
This carb with a new cable and throttle perch. You can get one for about $20
Carb was only $40 but it’s a replica
@@garbinsgarage What's it called? Ebay, Amazon er sumwhere else? Same jetting as the original? (ordering jets right now)
@@garbinsgarage Any idea what the actual SIZE of a 120 main jet is?
lee isenberg .012 inches I think or .12 they make really small drill bits in those sizes
Escapament Made un Brasil? Pro tork power core?
Victor Veron si
Are you have ever problems with overheating engine because using 11:1 compression ratio on air cooled engine?.... tnx, and sory for bad english..
AnTonY no issues what so ever. I only heated up a little bit on a trail ripping 40 mph and rev limiter for 20 min straight
If my bore is 67 van I use 65.5 mm piston?
No. Use the piston intended for you are cylinder bore. They sell a 67 mm piston
I can't tell you which piston you need
for sure Shavon, but if you have
a 67mm bore, matched piston
might be called '67' but that would be a
'nominal' figure, it sure as heck better
not be 67mm literally. In other words,
if you have a 67mm bore, you def DO
NOT WANT a piston that is literally 67mm.
Pistons are sized in order that rings finish
off the mating of the two surfaces;
Cylinder to Piston.
How much was the new carburetor ? US or AUD or something else?

@@garbinsgarage thanks a lot for the information
Ah so those valve noises are normal , I figured mine made the noise even after adjustment.
Generic Girl yeah this bike had paranoid me to the point where I tore the engine down and replace the timing chain and still had the rattle so it’s pretty normal Eli guess
Just brought a 2005 , it’s noisy,adjusted the valve clearances, still rattles a bit , I was going to tear it down, maybe I’ll just leave it then.
Ian Frost yeah they tap a lot being an air cooled engine. If I get mine adjustment perfect while it’s warm it’s much quieter
Garbin’s Garage Okay thanks that’s good to know , I adjusted the clearances to .004 with a cold engine.
Just wondering if you made any suspension mods,
Garbin’s Garage Okay thanks that’s good to know , I adjusted the clearances to .004 with a cold engine.
Just wondering if you made any suspension mods,
I was wondering how did you take off the front shock boot and what did you put instead?
Mathieu Blinn they slide off the fork when you loosen the screws but the whole dirt or the front wheel has to come off. Mine were ripped and faded so I got seal savers
Garbin’s Garage can you please give me a link to where you got the seal savers please?
Mathieu Blinn you can find them on eBay or amazon. Just search it up
Hey, what is the top speed? I have a stock 2009 230 honda dual sport and it only goes about 70 mph. I'm looking to get it a little faster, so how would i go about doing that? would it require a new engine?
Amare Skateboarding. Mine only does 68-70 mph in 6th gear at rev limiter. The o or thing that will get you a higher top speed will be changing gearing. The stock sprocket sizes are 15 tooth front and 50 tooth rear. A smaller sprocket will raise the ratio giving higher top speed. I would put on a 45 tooth rear sprocket
I have the same bike 2008 crf230f. Will the 45 tooth rear sprocket make you lose a lot of bottom in speed?
Tyshaun Cobbs not really, the low gears are a super super low ratio so if anything it will make 1st gear more usable instead of only going 5 mph
No volume
hello, what was the porting of the head? thx
!
That is grinding out the intake and exhaust ports in the cylinder head. It’s for better air and exhaust flow
@@garbinsgarage thanks ; )
@@garbinsgarage how much did you remove
@@YourDome_ about 1.5-2mm larger than stock
Did the carb just slide into the stock manifold
X7rocks, not exactly. I had to make my own by attaching a piece of rubber into the old one
How to pilot jet and main jet nomber
What carb did you run and where did you get it also do you have a rev box
also to add to this for me:
1) what is the carb's jetting settings and your riding elevation?
2) What did you have to do for the throttle cabling (push/pull/single)?
3) how did you do to fit the carb back at both ends of the air & intake manifold?
thanks inadvance! And how awesome in the same day 2 ppl trying to steal your carb mod :)
Matthew Miszkiewicz carb is from amazon. Just a China replica. And no rev box. They don’t make one that is useful in the us. All the us ones do is remove the rev limiter even low Pierre drops off before the stock 9800 rpm
David Deir David Deir I have whole video on the car if you wanna check it out. 1)The jets are 135 main and 40 pilot at about sea level elevation. 2)The carb came with a new throttle cable and perch(it was trash though) 3) it barely fit into the air boot but I have to mesh together the stuck intake Manifold and the small rubber coupling that can with it
What gears do you wear my friend
Why is there a G-Shock strapped to the bars? 😂
xXFARM3R BROWNXx, hey man if I’m at the track I don’t wear a watch so I have to know what time it is😂
Oh ok😅
Hey man I’m looking at doing up my 230f it’s an 08 model and I was wondering where you got your plastics and graphics and things like than from
Brayden Heal. Sure thing. The plastics are actually stock from 04 and the side panals I I painted but I don’t recommend that. Then the graphics are from eBay and other little stuff is from amazon
where did you get those plastics?
eBay
Hi, whats the jetting on koso carb?
135 main jet and a 45 pilot
I have a crf250r that’s the same size and makes 45+ hp and has hydraulic brakes aluminum frame inverted forks etc
Hashim - 250r is a little bigger with a totally different engine. The piston is actually 40% bigger but the stroke of the piston is smaller that why they rev so high. Also they have a huge carb, aggressive cam, and very light internals
Hashim - nope not 45 hp, unless is a full built n still
Martin Bonao 42 from factory. Even the old ones
Garbin’s Garage I have ported head and power commander thohgh
Yes, that's right. We have the choice when buying a bike over performance or longevity. My CRF230 is well suited to weekend trails .
How much was the rev limiter
kuoz it’s the factory one. 9800 rpm
I have a 2003 crf230f ,how you do it please , 💀💀💀
do u know the torque
Richard Ziminsky, just a rough Guess from ridding it stock and other bikes
But I’m guessing around 20-22
@@garbinsgarage either way very nice build
lol.. 26 hp.
Y is that so hard to believe every little mod adds 5 hp not to mention the big bore kit .... I can c it hapining....thanks for the video.and don't worry about the hatters he probably drives a Jr 50.
