Hoping to make a video showing this thing really tearing it up off-road when I get a chance. As for the in-depth discussions of each component or the build as a whole.... That type of stuff just doesn't get views, so I'm figuring out what to do there to make it worth the time expenditure.
@TortureTestMagazine hey mate, good vid. I think the videos of you wrenching and installing the mods plus a bit of voice over and then an end result would be awesome
I get it if you find that a in-depth build + testing sort of video isn't worth your time for the views you get out of it, but I just want to say those are my favorite. Watching some of your older content along those lines is among my favorite moto content I've found on youtube! Thanks for all you do Gabe. Good luck to you!
Hi man, your content is awesome!! Can you do a video on how you took the decition to change your life and to go all for it. Also how your time has been during your Projekt. That would be really interesting!!
I have seen these engines be opened to 310ccs. They're the same engine that came on the Brazilian CG150s. It's freaking huge around here, #1 top selling bike for 10y if I recall correctly.
@@Noonenaught yeah, recently there was a race between builders and they are now mad at one of the builder because he used nitrous oxide (and won the race).
The improvement is insane! I definitely agree in the de-tune so it's more usable in the offroad usage. I definitely still think I'm going to get a dr200 and a play around dirty dual sport.
I have a 2004 KDX 200 that I love. I do a lot of different trail riding here in Central Oregon. Do you ever foul spark plugs? if you do, consider switching your pre-mix oil to Lucas semi synthetic Land & Sea 2 stroke oil. (Amazon). Expensive but it is designed to burn off the spark plug and not leave oil on the plug :) That and use an iridium plug. I can put around for hours at barely more than idle and not foul. Just my two cents on KDXs.
A great video my dude❤, just a suggestion if u can find aftermarket racing cdi, racing ignition coil, port and polish the head for better performance, i guarantee it'll give u more power than having bore up, here in asia we call it pcc (port, carb, cdi) it can keep up with the bore ups (sometimes much better)u just need fine tuning on the carb have it on slight rich tune for high revs without limiter comes with a cost on the engine😅, it'll save u more aswell on the modifications❤, pcc and stiffer valve/clutch springs, also replace the clutch lining. Lemme know if this helps😁
I'm currently on a TMX Supremo, which has the same family of engine as the XR150L (minus some differences). I've taken the engine apart (topend and crankcase covers) to do some preplanning and CAD work as when I get the XR150L I plan to replicate the Suzuki's SACS oil cooling system by modifying the head and jug to have cooling oil galleries/jackets and installing 2 CRF150L cooler kits from a reputable Indonesian shop, with one radiator line bypassing the stock oil channel in the jug and directly pumping the oil to the head cover gallery. The other kit will be supplemented with a thermostat and an external electric oil pump with an inline spin-on filter before plumbing to the added cooling channels. Both radiators will have fans as well. Will it work? I honestly don't know, but I'm bored enough to try it. I'm sharing this just in case anybody wants to be as stupid as I am.
Hi man, your content is awesome!! Can you do a video on how you took the decition to change your life and to go all for it. Also how your time has been during your Projekt. That would be really interesting!!
Awesome! Now we just need some raw 0-60 and off-road footage before you de-tune it. Crazy how much acceleration it gained. Did that spark arrestor bolt right up?
What an incredibly effective big bore upgrade! Wow. Not everyone can say there's such a firecracker of an upgrade available for their bike. About how much horsepower do you think the bike makes now at the rear wheel?
I don't have a dyno to work with, but I've got a phone with accelerometers saying it's tugging 2-3x as hard depending on RPM and speed, haha. Definitely indescribably more powerful in the bottom to mid and then starts signing off in the top end because the cam profile just isn't working with my 15,000 mile valve springs. Definitely a lot of potential in this engine if it were given a well thought out build rather than a mish mash of bolted-in parts!
Also, gotta be careful on the head gasket.. Doubling up can increase the squish band and paradoxically make detonation worse. Not sure if anyone has blazed that trail on the XR150L but you never know.
Dare I say a bigger cam may actually bleed off more compression with more overlap and make less knock sensitive. Measure the squish too, a tight squish of around .040 helps with knock too.
I have a possibility dumb, very expensive but interesting idea. I was reading through the old crf230f mods website and I was kinda surprised that the pwk carb was straight off of a cr85. Then I had a horribl(y good) idea. I looked up if smart carb makes a model for the cr85. They have a direct bolt on. Since you converted your crf230f to use a cr85 carb already, who's to say that the smart carb wouldn't work either? It would probably also solve the jetting issues described in the article.
You proved several points & that's good enough but w/o adding anymore power a simple "Sprocket" experiment might have made the low end gearing better while giving a slight advancment in the overall speed of the bike? ME, IDKnow jack-sH!Te about most of this but I have seen the big block upgrade you did. ANYONE know what he "Coated" the big bore parts with? Is it a some metal coating to better protect the engine parts that you added? Do share, drop the name of it if you know? peace
If you could send me your speedometer and tachometer readings for every run and give the bikes weight with you on it along with a head on photo of you replicating your body position on the bike, I reckon I could get an ok estimate of the bikes power at the wheels, if you can get me your gear ratios and tyre size I could see if I can get a rough power versus rpm chart and torque versus rpm chart for you, in principle it all should be correct but ofcourse the real world is way more complicated so I cant promise much
2:11 wow, Honda really nerf/ underpowererd your xr150L in the USA to avoid putting electronic fuel injection on it. The NXR150 Bros, which is the Brazilian counterpart of the XR150L, does around 12s at the 0-60MPH factory stock with this same engine. Source: me, who owns a stock NXR150. I like the XR150L, for us Brazilians it looks like a vintage bike because it's design is almost the same of the original 2003 NXR150, so the XR150L looks like it got frozen in time because the 2009-2014 NXR150 got numerous visual and technical enhancements like electronic fuel injection, better front and back lights and a fuel indicator, the ability to run with also ethanol in 2010, etc. In 2015 it got a new 160cc engine and became NXR160, a less sturdy engine. But all the basics like wheels, suspension back and front, tires, frame, handlebar, etc of the XR150L are the same of the NXR125 and NXR150 from 2003.
Hi Gabe, what the hell happened to your hair!? And WTF happens in US with the XR 150 L? There are so many videos about it, I (as French European) can't understand why it's such a fancy bike out of Indonesia or Vietnam! 😉✌️
How did a bigger carb help performance? Isn't carb tuning all about proper air/fuel mix under load? If you need more fuel you need more fuel, but wouldn't a jet swap do the same? The increase in displacement wasn't that big.

My DR200 has been abused so much and still takes it. I love that bike.
Loving the XR 150 content, hope to see a build continuation! I appreciate your work sir.
@@WheelieBad i make xr150l motovlogs! Check me out! ✍️

For real the racing videos were so much better
Racing with the XR 150 L? Maybe?
How to make a beginner bike fast... Gabe's specialty!
i say slap the stock cam in and leave the carb alone if the motors happy with it
I was literally on your channel last night looking for any updates! Low and behold!
Yes ! show the build .Still love my kdx in the Maine woods .

Dude you are a legend. Making me wish like heck I'd just kept my XR150L
Do this to a TW200 please!! I really need to see that bike with a good setup!
Great job as usual Gabe. Nice real-world comparison.
Time to strip it and race it now!
Some upgraded valve springs will help with the float
Double up the base gasket, a la DRZ400S and SM as compared to the E
Love this type of video
I would really love to see you get your xr250r back out. I have a electric start bottom end for the 250r I know you’d be interested in 😉

Nicely done 👍
Thank you sir
id do stronger valve springs and detune just so its ready for when you want to open it up maybe for a race weekend
Dang, thats downright insane!!
Yep! Surprised me how much it came alive
Does cometic have a thicker base gasket available? Maybe just lower the compression a tad?

@@TortureTestMagazinedo you think a crf230 engine swap would be an upgrade from the big bore kit
A stock 230 engine, nah. I have one of those parked right next to this xr150l. It's not as fast
Wish you posted more!
Awesome!
Also, gotta be careful on the head gasket.. Doubling up can increase the squish band and paradoxically make detonation worse. Not sure if anyone has blazed that trail on the XR150L but you never know.
Very nice!👍
That’s awesome. It sounds like the stock carb would be your best choice. I wonder what else is lacking now? Longer swing arm and beefier forks?
Dare I say a bigger cam may actually bleed off more compression with more overlap and make less knock sensitive. Measure the squish too, a tight squish of around .040 helps with knock too.

Place links to the kit products please.
Get stiffer valve springs. Might need to upgrade clutch springs with the extra power.
Did you pull specs on the cam?
very cool. did i see that correctly real 55mph are 100kmh on the speedo?
You know we’re so back when you see an OKO carb on a small ass bike
So how does it compare to the modified DR200 you did?
Does it have an oil cooler to help with detonation?
What the the names and brands of the parts you use and espects
Do you need to grind down the back of the piston?
To install a bore kit what is the difficulty?
And now it’s time to run in in a 24 hour race 😂
I wish all L model Hondas weren't trash. Love my XRs though
L is for late. Lazy. Lackadaisical. Lame. Low maintenance.
Make more content please 😁
I'd regear it, so you can cruise at 65MPH without being a hair away from valve contact.
just put some 2 stroke premix in there at 125:1 and it won't knock or 100:1 for better over all running
Thicker base gasket reduces compression ratio. Probably the easiest way to detune this beastly XR.
daddy gabriel 😩

I wonder with gearing if it would do 80
Indeed it will. I hit 80 today on it

Give a more detail instructional about your build; cost time to work on and etc.
Almost as fast (0-60) as a KLX230

What if you need both? More air and more fuel?
why not just richen the mixture a little ? It will soften the power delivery and should also reduce the chances of knock.
