- Can we create the worlds best 125cc Motocross bike? We love a cool dirt bike build here on the 999lazer channel, and we thought it was about time that we gave a little 125 2 stroke the full works! We teamed up with our favorite two stroke tuner Roland Shaw on this project and have left no stone unturned to get the most out of a brand new 2023 Yamaha YZ125. Let me introduce you to the Minizilla.......

The bike looks sick…. Can’t wait to see her rip the track, Roland is a absolute genius, the Don of 2-stroke wizardry
Thanks for watching Dave
👍👍👍👍❤🎉
Definently would want to see the detailed talk about porting! maybe in a different separate video
No dyno, no numbers, no lap times? Maybe i have missed the video with that stuff, back to searching for more awesome videos.👍
wanna see these minizilla results!
Roland’s knowledge is priceless!!! He’s the Yamaha Genius.
Why can't Yamaha do half this stuff from the factory? It wouldn't cost them much. This bike will be mostly the same 10 years from now.
@@justincoats7236 because it takes the fun out of building your own…. The cost would be astronomical, & all other manufacturers would have to do the same…. Yamaha as a brand have always produced a very capable bike. It’s up to the owners to make it how they want it. 👍🏼. Also what Roland’s made will be similar to a Factory spec Motor. 👌🏼
Great video Max, you have us all hooked on the new mini yzilla project, what you're is awesome. God we would all love to have a friend like the genius Roland , can't wait for the next episode , Jesus max your smashing it.
Thanks Kevin
this is amazing about to buy a 125 for next year to practice on for racing and wanted to get some factory parts for it and i now know what to get from this video thanks al ot lazer
Are you feeling that's products in Yamaha, Kawasaki, KTM,Honda in special engine 2 stroke & 4 stroke?
MAX great video! Would like to see you build a yz325 and a tuned yz250 then you’ll have a full fleet of these special Yamaha’s and then see what’s fastest around different types of tracks
That would be cool!
Why can't Yamaha do half of these mods for the next year? They won't do anything. They should have 10 times the knowledge and engineers as Roland. It wouldn't cost them very much.
I'm building my lambretta jet 200cc at the minute it's a 225cc kit being ported and stroked from a 58ml crank to a 62ml crank should b close on a 250cc once finished, different kettle of fish but I'm still on a 2stroke 😜👍
sounds awesome Andy, its going to be a crazy fast Lambretta!
@@999lazer hopefully with a 5 speed gearbox 90-100 mph😜👍
I just wanna know something, does the tail prevent from splashing of water and mud while driving on the road???
£610 Suter Mx Line clutch with diaphragm spring. @13.40 If you listen carefully there is some slight slippage(ha,ha) around the word 'instigates' about the clutch basket used, The Suter comes supplied with inner hub, but one has to use the stock outer basket? Is the carb a Lectron? Brake mean effective pressure is what he's trying to say @15.08
He's a Two Stroke tuning God .
haha, I think he'll like that
Nice Bike. Would love to see you and Roland compare a good old carburetor to the new school Lectron and Smart Carbs. Would be interesting to see how they affect the powerband and which one is the best. I bet Roland's carb tuning could beat anything else on the market but would be cool to see a track and dyno comparison.
Great suggestion! We'll see what we can do :)
Those carbs aren’t good for high level racers. No one ride with those in EMX125 or schoolboys1 in the US. Many people were putting Keihin carbs on KTM’s too as it’s better and easier to jet than Mikuni
Ya. I agree but it would be interesting to see how different the carbs act on a dyno/track.
Lectron and Smart carbs been around since the 80s they have always been trash 😂
Great vid Max, can you ask Roland does the heavier crank pin negate the need for a heavier flywheel ?
I love the Yamaha bikes
Where did you get the crank/piston setup? And does Roland work on public bikes or is he private only?
F*ck! You just did exactly what i wanted to do :/ but without big bore cylinder and some other parts
Cant wait to see the track vid, minizilla look and sounds insane 🔥🔥🔥🔥🔥🔥
😍👌🏻looks the size of an 85,looking forward to seeing it go👍🏻
Love it. Love all.the details. Would like to hear more as always. Such a great learning experience from Roland. Fascinating listening too him.
Thanks for watching Benny, wait until you see how well it goes on track... ;)
@@999lazer can't wait. Sounds lovely a crisp !! Looking forward to seeing the dyno numbers
Get back to working on that new ktm 125 next 😮
Nice setup! Back when i ran a longrod kit on my 95 yz 250 we had to run a stock piston but longer rod, cyl spacer and 2 base gaskets. It was great in that bike.
Brilliant video. Very interesting.. especially the part about the cooling...as someone with a tuned 2005 Yz125cc can you tell me what fuel is being used as ive had problems with regular petrol and super unleaded with pitting my cylinder head 😀
Thanks for watching
I love to see him at work he's great to watch I'm finding out a lot thank you
Thanks Darrell, We have some more cool build videos coming soon. The next one is pretty special :)
Can you explain the stubby spark plug??
Its beautiful
For my 04 kx250, as someone who has not too much mechanical experience, what are some basic things I could add or change to make my bike better?
Great video! But in order to be the best 125 in the world… shouldn’t you work on the suspension and brakes too?
Nice bike. I have a question, if you tumble the gearbox at 0-10 hours will it wear out faster when the bike is older?
no as it doesn't affect the gears in that way. My personal bike is a 2011 Y125 which had the gears "super polished" when it was new and it is still going strong.
125CC 2 stroke i more fun...it's not gonna kill you :D
As long as it’s a Yamaha I’m in ✌️🇺🇸 she’s a rippa
T. O. B! Sounds great! Little zilla, Lill"Zilla, or LillaZilla... Minizilla ok..but LittleZilla better! I'm just bugging....but it is better 😄🍻✌🏻
this channel should be named: best content for 2 stroke lovers
When can we look forward to the follow up video?
sounds crisp
Sounds so good! 🤓
Great vid, how do you think it would compare to the full GYTR kit?
Good question, we will see if we can do a comparison. Thanks for watching
I have a GYTR kit in the stores some where could be worth digging out to compare
On track it’s good but needs the 113mm rod to complete the package
Another interesting video lad well done.
Glad you enjoyed it
I wonder what ever happened to Lazer Helmets in Belgium?
Funnily enough i used to wear Lazer helmets back when i was a kid, i loved the designs so much. That's actually where the 'Lazer' in 999lazer comes from!
Great build
The y zed. Yz
Katie em. Ktm 🤣
Any chance you can release video where Roland is talking about porting in details? I would love listen to it
We'll ask him :)
@@999lazer lovely mate! :)
What brand are the radiators?
Race Rads. You can contact Roland at www.motocrossdirect.co.uk/
That's 1 cool looking bike. I'm sure it'll go as well as it looks. 😉👍
Thanks for watching. You wont have long to wait to see the first ride:)
gold rims are on point max. nice work
Thanks Ian
amazing bike mate and i cant wait to see it hit the track and rip some ruts
Not long to wait until you see that happen :) Thanks for watching
My wife replaced me at night with a hand-held Tumbler. It's kind of suspicious she calls it "Roland". You got sum splaying to do Mr.!
Very nice work😮
Thank you! Cheers!
I’ve a mate that engineers 2 stroke engines like Roland and he did one of my Stihl chainsaws on the side. It’s absolutely unbelievable now I keep it as a show off saw 😂😂
Oh that sound 😍
Heck ya we gotta see u build another big bike like the megalodon but more ccs
haha, keep watching. We have another big bore build underway. It wont be long until we release the first episode :)
Great work. Cool video
Thank you! Cheers!

Mugen Honda had a works bike you could buy many, many moons ago. It was a sub-200lb 125 with a full works Mugen engine, loaded with titanium with what was then works suspension. It was actually too light and exotic to run in US AMA Pro races because of the production rule- it was too light. It was also much more powerful than a stock CR.
Porting secrets are no secret to me- Ive been removing metal and reshaping ports for yesrs too..
That guy was giving years of experience and you edited it out. Dafuq!
The worlds best 125 is actually a bored out 125. Like a 134cc or even better, a 150cc. A ported and milled carb works too. Basically, its a cheater bike
Cylinder is just ported not bored out, still 125cc he says that in the video, not cheating
Are you running the VHM GET ECU on the HCR tuned engine? What jetting is on the new HCR engine?
If your not building good crank case pressures on the down stroke your at nothing
Whoever thought the color scheme ought to be yellow and red should be slapped...
the old school theme is so sick! the first bike i ever had was a 1983 yz125, those gold rims are sweet!
Thanks for watching Corey! I'm so happy with how it turned out :-D
Strokin'
Can you guys do an electric water pump?
Looks great
Thanks Tony
Roland only wants to help you grange hill tuning
Man I love seeing the wizard at work my question is are those radiators available for any brand 2 stroke and if so is there any information or link to get some
I believe so. You can get in touch with Roland via www.motocrossdirect.co.uk/
Fine looking machine
But it’s not a Honda how can it be the best lol looks good but
sounds nice Bud looks great what year is it 👌👌👌👌👌👌
its a 2023 YZ 125 Rumpel
@@999lazer love the white and red look amazing
Please share where the rads and hoses can be purchased. 7:02
I show you the cake but not the recipe Oo
Es preciosa esa moto...saludos
Good knowledgeable video..!!!
Put a 250 engine in it fastest 125... chassie lmao if your guna bore it out it aint a true 125 so might as well get a bigger engine on same light weight feeling frame
its not bored out its a legal 125 motor , but we did put a 500cc 2 stroke in a YZ 250 chassis th-cam.com/video/uEmwZHB_Xag/w-d-xo.html :)
@@999lazer yeah man, ive seen that its sick that bike is love the colours as well man excellent build
It isn’t bored out, nor is the stroke any different, it’s a longer rod to change the rod-ratio, and a shorter piston to retain the correct piston deck height.
@@mozer30 i thought thats what porting the barrel is technically boring it out but i dno i aint a mechanic lol
Q código de cilindro es
Who sells those radiators
My 82 RM would embarrass the rider of that machine !
Omg GREAT JOB GUYS
Thankyou
Subbed
Incredible video!! Roland is the man!!!!
I could listen to that bike all day.
Hi max, any more info on the custom rads roland has in his hand and will they fit my 2020 yz125? Loving the project and in using allt of the same methods as roland to get my yz125 race bike ready👌👍
Hi Alex, Roland's company makes the rads. They are pretty trick and I have them on my own 2010 YZ 125 too. His contact details are on www.motocrossdirect.co.uk/

Then go to goyimtv and get to work!
i would really love to watch a full detailed documentary with an explanation of all available tuning options for 2 stroke bikes. Really loved to see how he turned this bike into a race machine. I have a 50ccm derbi senda myself and cranked it from stock (3PS) up to 25 PS with less than 500$ of parts. Tuning really is a great option especially for low ccm bikes. 🔥
Show us the Dyno with your 50 making 25ps.
1st
I used to love 125's then I turned twelve and have been able to get one that feels like I'm not completely wringing the guts out of them just to get one to go.
Love your content❤
