Just scored a Baja from a junk pile too,timely video for me,thanks for sharing RB
Need to let it slap that power band you shifting a little early
He will be flat on his ass too🤣🤣🤣🤣
Thats not the problem...theres weight issue....Biggen needs a loose a pound or 2....🤬☠️
Man I have been waiting forever for y'all to do a mini with a two stroke! Yes, that thing is sweet bro! I can't wait to see what all you do with it! 5 stars RBG👌✌️!
Two stroke engines are sick as hell scary fun cuz it's a 2 stroke lol HELL YEAH!! SWEET BUILD BRO👍👍
Y’all have the best builds
Red beard by far on of my favs you've done on your channel this is the definition of a good old boys bike.
So happy you came up in my recommend suscribed and bell on even though its 430 in ky so yeah caught me chillin and found a dank channel keep doing you brotha
You have made life so much better. Thank you for the link, I am ordering the carb kit, seat, etc. Thank you Red Beard
That sweet 2 stroke sound!
yup it sounds like a pissed of weed wacker
Charlie hunnam off*
Love when that powerband kicks in and it gets rowdy and fast haha
I've been watching since the old virago days and I've noticed you guys have never had an ultrasonic cleaner it would be a great addition to the new shop they work wonders on old carbs anyway keep up the great videos.
He said that. Are you donating?
Yes, do the swing arm before tuning it because its going to be a wheelie MONSTER! It's probably at about 60% power right now. Take it to a shop that's well versed in two strokes! After they laugh for about 20 minutes at you, and telling you how insane it is, they can set it up for full powerband... lol I Love This Build Guys! Be careful you don't flip it over backward when full powerband hits the first time... not kidding!!! Can't wait to see it in full power INSANO MODE with a swing arm! AWESOME BUILD!
@fenian p0wer He admits in the video that he is not well versed in 2 strokes which is awesome! I appreciate the Honesty! I am merely saying go and learn what needs to be done then he can do the DIY! Don't get me wrong! I LOVE EVERYTHING Greg and his team do!!! LOVE IT!!! #RBG ROCKS!!
Meth
Its great sir!👍🏻👍🏻👍🏻 from 2 stroke lover🇲🇾🇲🇾🇲🇾
I once mounted a 4 stroke Honda 90 engine, 4 spd auto, with Hi and Lo range, on an old 70s rigid minibike. Best minibike ever!
Heck yeah man 💥🔥💥🔥
Linda de mais...adoro o vídeo de vcs...me inspiram muito... parabéns...eu aqui do Brasil acompanho sempre. Show de bola
Might hit powerband quicker with a little less gravybones on it 🤣
man o man i cant wait to come rip that mini bike its going to be nasty another quality build from the beard !!!!
Awesome vid👏👏👏🔥🔥🔥
Nice ride guys
Thank for the video
Last Time On .... Xmen.
Loved it. Nostalgia city.
U guys make wats I was thinking 🤔 rad build man I'm definitely sub n like 👍
You can’t really let those 2 strokes idle much, especially since you fattened both jets. Both of my 250’s are super sensitive to jet changes and especially expansion chamber changes. Getting a good expansion chamber makes a huge difference. This build is awesome though.
Great job👍
its cool to see you guys do this . Back in the day (70s) there was a company that offered a 80cc engine kit that would bolt right up to a mini bike.
No one was smart enough to make one at home in the 70s lol
Looks really nice
That thing rips !
Sick love 2stroke
I admire you guys for fixing that. It would have for sure been easier to just buy a new frame and parts lol
From my experience with two strokes there easy to work on but hard to get tuned just right. Not as forgiving as four strokes when it comes to jet size, float height and needle clip position. The last two stroke I had took forever to hit the powerband because it was running way to rich. Took it down a few sizes and it solved that problem. The power hit much sooner and harder.
What a RIPPER 💪👍😎🏍💨💨💨💨💨💨
That’s aweaome
Man that welder sounds dialed 👌🏼
Had a 81 cr80, then 125. Then a 84 cr500 that tried to kill me many times. Lol. Love the sound and smell of 2 strokes.
Red beard love your videos
Plug one end of the exhaust with a cork or something and pour a good strong caustic soda mix in it to clean the exhaust inside.
Burn the exhaust out with a heat gun repack the silencer..... she's not running right that thing should be standing up every gear
Because his dumbass cut up the pipe and rewelded it
@@junkyardboost8372 As long as the length and other dimensions remain the same, the exhaust pulses will return at the proper time during the rpm range the engine was designed to run at, and will keep the fresh fuel/air charge from exiting before ignition. The engine will not notice. I used to design and build exhaust systems for two stroke engines before the internet was a thing and remember 4 pages of equations being normal to get in the ball park with the expansion chambers and stinger length and diameter.
Standing up with a 10 year old on it yes
@DR Dan yep, rev them till you hit rev limiter, shift, rev limiter shift, they clean out like you said once they've been whipped on
@@sandmanbub yeah so long as he hasn't altered the length and put to tighter bends in he should be around the ball park , it's banding but not near anywhere of a standard cr80 with a big guy on ( yeah we all have big mates who wanna go ,suspension on the floor it still try lift the front wheel ) , finese the front pipe , it's so awkward to get spot on but worth it once it's right
Red Beards Garage with a white US General toolbox. I figured you'd of gotten a red or orange. LOL These bikes are so fun. Good video. Keep em coming.
Yep , your just a bunch of Wild and Crazy guys .
That stand for that portable bandsaw is fucking brilliant!
Man that bike is so sweet great job bud
Love the two strokes it looks like it gets along pretty good to can’t wait to see what you are going to do with these awesome new toy
I’m so pumped up about this one hopefully one day I’ll have the funds to build sweet bikes like this
That old brownie pan has seen some use!!!! lol
Sick
Try changing the idle air mixture some. It doesn't sound too bad at WOT it's getting there that sounds wonky. It almost sounds a little rich when you first crack the throttle so go leaner on the idle air screw and then it sounds lean coming out out of the pilot jet so the needle clip may need to go down a notch to get some more fuel mid range. If you get it to rev up to WOT then you can do a plug chop or two to get a handle on how it's doing. I'm very surprised it's running that well without the factory airbox. Honda bike are very sensitive to that.
Stupid fast lol, love it
love this channel found out today youtube has not been notifying me of some of your vids caught up with a handful wheres the rest of the fl250 build love those old odysseys love to see em still alive...did you inspect the reeds on that mosquito killer lol
Hey look Ma it’s Redbeard the pirate 🏴☠️ 🤘🏻🐿🤘🏻 imma dign the bandana bud 🤘🏻🐿🤘🏻awesome video
You.posted in 6am •>• duuuude
Shout out from Ocoee,Tn
Lower the needle clip one slot
Just needs rear suspension , it’ll be a killer ride. Awesome way you made something from basically nothing !
awesome build! man you better gusset that frame they crack by rear lower tube by engine plate. ive had a few of theese lmao
This is what I need to do
i gotta get one of those
That thing should be ripping!
Bogging is lean adjust the needle clip and air mixture
And he shifts way too soon plus it's only a 80
I run a 52 pilot a122 main 3rd clip Up 4th clip works good to two turns out to me it sounds like the bike is running rich or your reeds are worn out
Keyboard tuners galore here.
@@T..C..M how many miles have put on a two stoke bike in last few years 10.000 miles my self
FUN
Love the vids man im from manchester Tennessee love what you're teaching to God bless you and your family in another vid you posted something about a pissy pants next door neighbor who wants to be in every body's life and business and probably 70 needing and the judge singing this or that probably tried of hearing from busy body old people it's a carma full world so brother man if I wanted to live there I'm living there and you're a better problem solver than most iv seen you got rights to man bout all I'd do is be quite ish past 8 or 9 and fire it up at 7 yeeeeeha I'm from here to
You should do a cr 250 swap one day little rich down low some tuning it'll be great awesome job
Nice bandana
thats what we built in the 70,s. alot of motorcycles lost their engines to us.
A white tool box lolol bro that's not gonna stay white for long. Sweet build man
Running great if you ask me hes a bit heavy for a 80cc and there gutless out of the powerband even the 125's got no bottom end
That’s a cool idea man. BUT that thing should be throwing rooster tails and be doing wheelies in almost every gear even with you on the front lol. I live in Sevierville btw. Love the channel.
You need to do plug chops to see were your jetting is. You stick a new plug in and run it wide open, then kill the motor, remove the plug and look at the insulator to check the color. You are looking for a tan color when you get it right.
I really hope you can pay off the new garage without too much stress! Maybe you should consider putting some sort of link to where people could donate directly to paying off the garage!
Check your reeds in the reed valve too
Replace them stock reeds to some nice Boyesen Reeds
Badass i was thinking about doing something similar with a Honda 200s Engine its would be like the old fat cats Back in the day
Its more dangerous then a BW80 I love it, best motor ever made in that CC by honda
Sounds like your running a bit lean which can burn it up. It also kind of sounds like your reeds are getting worn. Ive been riding two strokes for 20 years and they still give me a headache sometimes. Anyway theres my two cents hopefully with other comments you'll establish a good concensus. I got a real kick out of watching you ride that thing. Im still smiling and your looking like a pro with that tig torch I was a little impressed you did that yourself instead of sending it off. Thanks for the laughs.
👍👍
Hoot & a half ,super dangerous. 😜
I seen Lonnie stocking at Big Lots!
GE Master you got awful nice shop
2strokes hate idling . But it don't sound to bad I love 2strokes there awsome and snappy and I know 2strokes alot of them have oil injection .I do away with them and mix my fuel that way I allways know I have oil in the gas .I've had a couple that the oil injection stoped and drives the moter up but anyways I love that rig ..godbless
You are definitely a better mechanic than i, however my two stroke motorcycle experience tells me that its a little lean. More than likely the cause of the bog plus i didn't notice any smoke which tells me you are getting just enough fuel to burn for spark but nothing lubricating the cylinder. Also indicating more air than fuel . this condition will eat up top ends pretty quick.
Its a 80cc its movin with that weight on it not bad i would love it for myself
Have you thought about doing a JR dragster engine?
Whoop!
Some times those power reeds get plugged try changing them out
Where you get the engine mount for the motor? Im trying to do this same build. Need some help. Thx!
CR80s are usually High range bikes. If you're a good tuner, then you can get a decent mid range powerband for it. They are most the time doggy on the low end. They are bikes designed to be pinned all the time.
Can you do a video on putting rear shocks on a baja warrior 200? Or is it not feasible?
Flick the clutch
My 85 was the same way. But had a new top end. Kid before me smoked it. Them motors aren’t built for riding wide open constant. But the pipe isn’t your issue. It’s jetting. Doesn’t have to do with the pipe. It’s just a silencer. Does nothing really on a 2 smoker. It’s like a glass pack really. Just goes through a baffle to quiet it down significantly. Resonator really. But would could be an issue is a leak on the chamber some where. Probably the copper ring to the pipe. U only can put them on once really. But definitely the air box is an issue. But if u restrict that air flow a little bit I think u might be golden. They rely on back pressure. That’s how they run.
You can tell the ones who know what's wrong , the front pipe on cr80s are so finicky to get right when modified, once you been through jets, reeds , crankcase seals , ignition and what ever else you realise it's the front pipe is the problem ,just modifying it thinking I only made a small difference actually is a huge difference for it to band out cleanly, honestly rework the front pipe and when it's right it will make a HUGE difference, nice work red , Lil work on the front pipe and that will be stonking quick , fixed frame and wide tyre I dare to say it'll probably lift even with a heavy rider . Make sure you clean where you migged the neck inside ( it matters loads) and the smooth the bend out on the end of stinger ,hope it helps
14:25 Them 80cc's are strugglin 🤣
Good day guys, just wondering what you would you put this in a 1970 cl100? If not what would you do?
From one big boy to another get a few springs under the seat. It will help with the lower back.
😂😭
He mentioned that he is going to be adding a swingarm.
Redbeard where you put the original foot pegs right next to the motor and shifter you will have better control over the bike because you will be able to feel that I sent start sliding in your feet in that specific location faster than if they were farther forward
Put v force reeds in it that’s the best and probably only way to get rid of that bad bog
I'm doing a build on a baja mini 08 I want to put the vtwin predator 670cc on it but I need to know if I'd have to mod the frame or mount points to fit. I have chain drive as it stands and I figure it should fit size wise but it looks huge and I'm not certain would you be able to give me a few tips or guidance
Is your gao right on plug.its to rich at low rpm plus 4onces to gallon of fuel.
And it’s super rich in mid range mess with the air screw
Need to get it warm and revving high and then kill the engine immediately and read the plug. I’m guessing reeds need looked at, and possibly the way you cut and repositioned the expansion chamber is causing some issue. Possibly flowing better causing it to lean out. But as said in other comments, the bog sounds much more like it’s lean.
I have a question RB I have a 49cc Wolf Blaze Scooter I would like to put a better carb on it The one on it now has no adjustment screws on it I'm sure you know exactly the piece of crap I'm talking about Surprisingly it's been a pretty good scooter I've had it for about a year and half I haven't had a drop of trouble out of it What size and brand carb would you recommend for a replacement??? I done away with the big air box and put a cone filter on it and It definitely made a difference I think with a carb that I could adjust it would run a lot better 🤔🙄 Love the vids by the way 👍✌️
I'd love to put a YZ85 or YZ125 in my CT200U EX!
Great work but I’m curios look at this noise 😩.... Quick question what kinda exhaust is that? Or what’s the most comparable 1s to it?
Idk what you mean about the noise but that is all 2 stroke dirt bikes general sound. The exhaust is a stock expansion pipe with kawasaki 2 stroke silencer.
If you are looking for that sound, practically, all silencers will give you that sound. With some variation here and there
I'm betting you folks are working on acoustic damping for the new shop now, huh!?
