I know what you're saying... All 81 times you said it....
gearhead1234 Lol did you count
Yes he did"
i was going to count cheers
all good it's a hillbilly kinda thing i got better i only say it about 5 times a video now")
brian noel keep it up na what I'm saying peace from Norfolk uk
" I know what your saying " Brotha!
it's a hillbilly thing") thanks timothy S for watching")
your welcome brother
You Know what I'm saying. Ha ha
One of the best ways to improve overall performance that doesn't cost anything is to make sure the bicycle is assembled correctly. That means greasing and adjusting all the bearings, truing the wheels, making sure the wheels are in alignment. Then set up the motor with the same amount of care to ensure the drive sprockets are aligned correctly, and the electrical connections are clean and tight. Torque ALL the bolts on the engine, etc.
You will be surprized at how much better the total bike performs just by doing a careful set-up. Takes nothing but time.
Thank you Brian . Great video! I am on my second build 49 cc and you are helping me a lot! I am old man 64 years. I love riding a motorized motorized bicycle. I pull little trailer behind and don't like going fast on streets and sidewalks in Miami Florida
It was great hangin out at your fire pit last night! Thanks for your hospitality and generosity. Hope to see you next time we're through.
bro anytime just remember what you saw here last night and tell the story far and wide because we weren't the only ones to see it remember at least 5 other people stood and watched for over 25 minutes and it flew right over us twice. i ask you aging bro WTF?thanks for your friendship and support i be here when you come back and next time i got the buds bro")
Yal see a ufo nyom saying
Yes please? Where can we hear that story?
Your information is correct, you summarized your thoughts and I love the enthusiasm. You've learned from doing. Good video.
thank you paul for your kind words i try my best")thanks for watching
I agree this dudes great
Just bought a little 2 stroke to mount on a bicycle, so doing my research now. Very informative video, many thanks for taking the time to make it!
if you are interested this is the link to the entire playlist it has 55 videos in total and covers the entire spectrum of issues i dealt with this motorized bicycle build. th-cam.com/video/DA7ga4HgaYA/w-d-xo.html. thanks for watching")
you know what? No matter what we think about his vocabulary and oratory skills, be thankful for his efforts. He is not looking for fame or fortune. He simply wants to help others modify their bike without spending a fortune....thank you Brian, you did good
Casey George thank you Casey for your support and encouragement and getting the point of this video")
Hahaa "know what im saying" dude I wanna grab a few pints with this man and hear his story
It's pretty long hope you have lots of beer")
I'm a R/C Model Airplane nut. I think it was when I was about 8, 1959, I got my first plane. Been flying ever since.
Your Thoughts on these little bike engines are spot on.
This is all the stuff I would normally do to "Hot Up" any engine. Rule of thumb, the better the engine can breath, the better it will run.
Yup, I'm a Hot Rodder at heart,can't leave nothing stock.
The Beach Cruiser I built and ride has a few little things added.....
High Compression Head, Hotter Ignition, NGK #5 plug, reed valve, 4" extension on the intake. Finally, of course, A Tuned Exhaust Pipe. The engine might be putting out 1.5 more horsepower, big increase in bottom end. 32mph on the flat. This should improve with and bit more run time.
We humans put out about 1/5th of a Horsepower and bikes are designed around this. When we start putting engines on these frames things like bearings, add High Temp High Pressure Wheel Bearing Grease, Up grade the break pads with fresh new ones regularly, then just make sure all your nuts and bolts are tight, are things besides the engine that we have to watch.
We are riding," UltraLight Motorcycles" that handle like a bicycle. Diving into corners, at speed, is just fun.
Finally, Tuning and Maintenance are just the two main things that these Motorized Bikes bring to us Hot Rodders.
Now get out there, have fun and be safe.
not much more i can add to this very indepth resopnse there Keith so i will say thank you for myour input and support") please come visit again and subscribe to my channel...
Keep the education coming
Thanks for watching
File the bottom part of the intake and the top part of the outtake on the pipe too and on the adapter on the bottom you can drill holes in the plastic red cover for the carburetor
I got a 48cc recently 👌 still working the kinks, I need it for college commuting and state to state roadtrips
Ah your voice is awesome!
Reign of the Pacifist thanks it has been an adventure making these videos and I have learned to just be myself and the message. comes through in the end")thanks for watching

I don't care what you are bro thanks for watching")
This is hilarious. You know what I'm saying?
i pretty sure we all know what your saying bro") thanks for watching")
I feel like I know what your saying better because you keep asking 🤣👍 thanks for the knowledge 👍
I heard the cylinders usually come in backwards make sure the pin is facing the air filter side otherwise it will rub against the muffler tension screw up your piston so take it apart and check it it don't matter where the arrow is it matters where the pins are where they end you will see
Thank so much dude I needed this. I've been maintaining my engine and cleaning it and tightening up my bolts everyday when I go ride. But I needed this video to understand how the engine works I had a basic understanding but you explained it way better thank you. Ps (my buddy's and I in my neighborhood got motorised bikes and we all race him it's pretty fun so probably help me beat them lol)
You welcome little brother I have other videos on this subject check the playlist red speeder bike") thanks for watching")
J to the R-O-C
thanks i think???
yeah jrock totally trailer park boys with the you know what I'm saying every other word good shit man
Mafk
Trace Anthony lmao I was about to make a jroc comment
Only the legends will know
I do know what you are saying, yes, yes, yes. i noya sane.
Jay Packs best one yet you actually sound like me")
it was still good help man, had to poke fun. thanks for the vid. i got the same motor on a genisis 29" wheel beach cruiser with a combustion chambered exhaust and 18" ape hangars.
sounds killer bro") post a video let's see it...
I like listening to you for real,loving these bike vids
if you want to make the throttle pitchier pull off the bottom bit off the exhaust or just snap the muffler off but if you do it its a bit loud but its worth it
Very informative video!! Thanks alot
My pleasure!
If you sand some off of the mating surface of the head,you can still use the gasket.Same effect,no leak. Also,hotter plugmight lead to hole in piston or galled skirt."Knowwhati'msayin?
Cheers mate helped heaps Cause I was gonna jump in straight away and nos for it but you need new stuff for it cheers 🇦🇺
Great vid mate. Always good to see ones like these.
let's smoke a joint and go ride bikes brother
whoop there it is I down with it") thanks for watching
@@Brian136 you know :) works better than ") -- eyes fit the mouth slightly better lol
lol
I not a sideways person 😎
@The RebTek Channel I know alot of smart people that smoke, it actually clarifies there thoughts and blocks out useless brain chatter because intelligent people have a harder time relaxing and focusing on one thing at a time so go back to reality and use your brain before you run around trying to be negative on others airhead!
I love this guy you y'know im sayin?
Good vid this helps alot.

I've had TurboBuick1's chain tensioner for years, it so far has out-lasted 3 different bike builds and is currently on #4, only thing i've replace was the spring. Still using the the same wheel and fasterns. He really did make one hell of a product.
it's the only one i buy bro")
U K N O W W H A T I M S A Y I N'
Thanks for all the info :) Good Video
I see you got that spring-loaded chain tensioner- its nice but they charge way too frickin much for me- I just swapped out the hardware and bearing for good SAE stuff and twisted it into line then torqued the Shit outta it! Little bit of grease helps too.
Yup he knows his shit, SUBSCRIBED!
Finally somebody that understands the difference between doing something right and finding the fault in what is being said. Thank you no parts, no tools, no... It's a rare thing and greatly appreciated bro")
@@Brian136 Haha for sure man, look forward to more videos as well.
@@killaz123456789100 There are 55 videos in the red speeder bike playlist and another 30 something in the Magna Project plus related bicycle videos in bike of the day playlist. Somewhere around 150-200 videos about motorized bikes are/or bicycles in general have all ready been posted bro look around on the playlist tab on my home page ")
Use a pop can as a gasket for the head gasket a lot thinner and it won’t leak.

Say helo mr brian, great videos, continue, i saw you bought a new bike after, your be stolen, apreciate, when you get a new motor, & continue with your builts, thanks, old, suscriber, joe.
do your gas filter have an arrow on it. my filter turns down in the direction of the arrow allowing the gas to gravity feed.
yes this is correct")
We STILL get a chuckle every time this is shared. Know what im sayin?
Thanks Fred it is funny")
2.7hp is being very generous. 2strokestuffing put a 66cc bike(pretty sure it was 66) on his Dyno and I'm pretty sure it pulled about half that even though they're sold as 2-5hp depending where you buy it. My guess is the stock 49cc is right around there as well
just watched his vid today, 1.78- 2.45 was his best results
I DO KNOW WHAT YR SAY'N, I HAVE WATCHED MANY OF YR VID'S, THAT HELPED ME BUILD MY MONGOOSE BEAST, FAT TIRE BIKE, WHICH WAS NOT EASY, 2YRS & A BROKEN ARM,YR INFO HELPED WITH THE BUILD..........................
thanks bro it's guys like you that i do these videos for") thanks for your support")
THAX FOR THE TIP FOR THE CHAIN TENSIONER FROM MICHIGAN .MOTOR.WKS IN PORT HURON, I'AM IN DETROIT ABOUT 30 MILES OUT, THIS IS A MUST HAVE, KEEP ON ROLL'N BABY.........................................................
HAVE U BUILT ANY BESIDES THE "THE-RED ROCKER"
this comment has a link bro check it") did you do the hub adapter also? www.mmbikeparts.com/sprocket-adapter-s/102.htm
right-on, that was one of the first upgrades I did, along with racing carb, upgraded cylinder head, cdi three prong sparkplug and boost bottle, theres not much else i can upgrade.......................
Also putting a pit bike carb on the motor will help
bigger carburetor always helps bro")
Right on that's what I was thinking and hoping! Would you happen to know the sizes of the stock jets you mentioned that I need to change?? I've searched every and can't freakin find it... crazy. There is the small one and I'm thinking the other one you might be talking about is the longer tube looking one that the smaller one screws into? I'll check out that video! Thanks bro for your help man!
I’m using a kx85 dirt bike expansion chamber Also you can put the spark plug on the intake side so it fire on the cooler side of the cylinder
What are the odds! Thats the same exact bike that I have! Mine also has the 2 stroke 48cc engine. I love the design of that model of Schwinn Del Mar with the rear rack that is built in, its such a solid feeling frame for motorizing. I have been trying to figure out what year it was made but I have not been able to. Any ideas? Love the videos mate!
this bike is actually made by Pacific bicycles licensed by a company in Taiwan here is a link for a video i made talking about the differences between a real schwinn and this bike as always thanks for watching") th-cam.com/video/X1WrljJUOog/w-d-xo.html
love your videos your videos help me the most !!!!!!!!!!!!! you are a hero
Julian Santiago thanks but I left my cape at the dry cleaners") thanks for watching
This was really helpful. Thanks! 👍
Great video my man wish I lived there I got 2 of them and I didn’t put them together yet cause this video lol
Right on...
Challenge. Take a shot every time he says “you know what I’m saying “ you drunk?
Hey Brian you make the best videos on speeder bikes in all TH-cam I've learned a lot the past year off you thank you much ,,,scott from pa.
this is a banner day for me") first I scored a few cool ass tools then Bibbi tells me that the documentary we are making is in high esteem with the panel of judges that are reviewing it and now I get home to a bunch of people actually being happy because I have a good sense of what it is I do and the ability to teach it is what comes out naturally") thanks my friend you have made my day Noe all I got to do is eat and that is the best part")
Great you know what I'm saying
Yes I do little brother")
No I found it helpful .thanks
Thanks for watching*) and
You're great bro, God bless!
Thanks for the tip
Thank you for the help!
welcome Jesse knowledge is the power that needs to be shared and I am always willing if i have it") thanks please come again a visit")
Thanks a lot 4 the info u no what i saying!
Wow your city must be approximately 17.7482393493 miles by 17.7482393493 miles lol I'm just joking man but cool vid and some very useful tips brother 👍🙏
Thank you
You're welcome
Thanks for the video, gotta new sub
Great tips Brian, !
thanks please watch the rest of the playseries and let me know what you think. Here's the link: th-cam.com/play/PLKRmdCKcaPeYSFCSNZZptYctH8lIokW8F.html
You should actually take the studs out of the cylinder motor because they might be in too tight it's only aluminum you want to take it out and loosen it and tighten it back with loctite just finger tight then tighten the top with the lock washer
I know what your saying. When your saying what your saying . When you said it. You know what I'm saying. When I'm saying what I'm saying. When im saying it . . Thanks for saying what your saying I'm so glad you said it when you were saying it .That's all I'm saying. 😚
I suggest taking the exhaust cap off, feels like a different engine.
Cheech? Man I can’t get my crank arms to clear..😞 I want to cut off the entire baffle and leave the pipe..would I still have back pressure with just the pipe?
For a 2stroke it's the scavenging effect of the expansion of the exhaust gases in the big part of the pipe.
Sure u can cut it off and it will sound nasty run like a 750 kawasaki twin with the pipes cut off. All noise no power because the little piston is having to push the exhaust out by itself. Taking away the bottom end of the tourque curve.
U want pedal cranks to clear? Two ways --
1. Install the expansion chamber pipe from ebay
2. Heat the pipe about halfway between the port and the muffler - use your vicegrips grab the end of muffler and push in about 1" or so. Spin the crank - repeat if you need more clearence")
Thanks for watching
You sound like a man with a lot of wisdom! You need to keep making videos!
thanks for your support")
Yea, I know what you're saying, bro :^)
i know what you,re saying bro. good job.
That's about how fast those bikes go. 25 mph is what these 2 stroke 80 cc engines will go
Thanks for watching bro")
Spicoli! Fast times ! All i need are some tasty waves ! Ha Ha good to see you got a job ! Great Vids Dude ! I DO know what you sayin !
now that's a new one ") thanks bro i got some girl scout cookies...
great video 👍
Change out the china spark plug cable. I went with a universal 8mm automotive one. Its a tight squeeze into the CDI. Got a HUGE acceleration increase!
As far as the CDI when you get it unscrew each end and cut about a quarter inch off each end then re screw it back in
Just take a Time use find sandpaper wrap it around the end of a screwdriver tape it and get rid of any lips or bumps inside the cylinder head
this made my day XD
thanks for watching trying to get another speeder bike rolling so i can make new videos stay tuned things might be happening "0
He sounds like rocky
You are the Carl Spackler of motorized bicycles.
hey at least he got the fucking gopher dude")thanks for watching
I'm glad you have a sense of humor.
why wouldn't i? it's all in good fun beside how do you know if i'm saying it right")
I just want to know, what's on the back of your left hand, you know wat I'm saying?
A daisy on my wrist and hawk on the back of my hand
Once you ignite the fuel mixture it is same new sparkplug does not add anythink up.
Thanks for watching "/
Not true. If that was the case they wouldn’t make different temp, length, materials, electrodes, tips on spark plugs. I made a small gain from swapping from a standard to an iridium spark plug in my car. If you dump more fuel in, you need to be able to ignite it all, otherwise it’s a waste. More fuel needs more/better/hotter spark.
I love how you break it all down, my favorite part was when you said wait till it breaks then start modifying it, until then let it be what it is. I'll be keeping my eye out for some emery cloth and a nice flat surface too close that compression gap like you said. longer intake, hotter plug and wider output is like putting a quarter in the gumball machine and watching the result. Thank you very much, and I dig the way you talk, these people talking shit can't help it, it's probably all they do anyways so f*ck em
haters hate but what they don't know is they are only hating themselves for not being any better than we are") dude i gonna start making some cool stuff soon keep watching")
The # on your spark plug is the heat range not more or less spark......know what I'm SAY'N ?
😆😆😆😆👍👍👍👍👍You know what im saying .... Nice Bike lol
Right on best one I built so far")
i know what you are saying❤
I ALWAYS!!! Know what your saying..
great vid brother new sub
thanks at least you got the point of the video what most don't know is this is one of my first speeder bike videos and i was still getting used to being on camera. if u watch the rest you can see how i got better over time once comfortable with what i was doing") thanks for watching
brian noel yeah its all good im new to the videos too check out mine
I am so sorry. I found this to be a waste of time. But on the positive side, a good voice, easy on the ears. Next time maybe a less you know what I'm sayin?
Sincerely Alicia from Sweden.
Thanks for watching anyway there is a lot of good information here in this video more than anybody else's that you might watch
It has been on TH-cam for a number of years and is still in the top ten motorized bicycle videos catagory. I am sorry you feel you wasted your time watching it. In my defense if you look at more of the videos in the playlist you will see that my delivery gets better as time passes. Now 8 year's be later I still know what I'm saying but now it's more of an acceptable thing because this is me all the time") thanks for your time")
@@Brian136 Thank you for your honest reply. About the good information, I am not so sure. Perhaps the reason that it has been wathced so many times is the excellent title? But on the positive side, you took the critisism very well, and yes, I am sure you have improved a lot since this one was made. Perhaps it is time to renew this one?
Be well, and thank you.

You are welcome I sub back" )
Hi Brian... thanks for the videos!! I have a question for ya that is driving me bonkers. So I did some minor porting the other day. All I did was take out some manufacturing imperfections to the transfer ports and roughened up the intake port just a tiny bit. I also took some off the raised ring on the head for higher compression. Oh I also put the piston at top dead center and trimmed the skirt so the intake port has clear flow. The problem now is that the motor dies as soon as I get off the gas. It runs like a bat out of hell once I'm scooting but just quits as soon as I get off the gas. If I pull the clutch and give it gas it will stay on. Do I need to jet up now??? Or maybe cheesed the porting?? Thanks man
yes sir jets is the answer") try this first on the main jet that is at the end of the throttle cale has four grooves at the top of the jet it should be at the second one down (stock) this is middle lean try moving the jet down on and see if that works first. it you still have the same results then you need to get the next bigger jets all of them because all of them need to be changed. should be 2 of them for most standard carbs that come with these engine kits. I have the NT SPEED carb and it worked really good out of the box so i just experimented with the setting on the main until i got it right and left it there. watch this video and you get the drift") th-cam.com/video/0F-Vyv5WmO8/w-d-xo.html thanks for watching you got more questions i got more answers my friend")
Do you know what the fuck im saying haha 😄🤣😂🤪😅 this is funny

Any tips for chain tensioner bending in to spokes? Messed up two tensioners and rims from chain getting loose, had tensioner tight both times.
JackTheRiffer masked guitarist yes change the stock tensioner out for the hub adapter set up from MMBIKEPARTS.COM it cost a little bit more than the cheaper versions but well worth it. I bought 4 for various builds and had custom gears cut . They use high quality aluminum billet and bro you want safety and performance look them up") thanks for watching
brian noel thanks for advice i have already ordered a engine mount tensioner from amazon but wont arrive till friday they said, plus sprocket and adapter cant wait.
How can you tell a 50 from a 80cc. I have motor but doesn't specify on the CC's. like most 2 stroke motors.
This guy sounds like cheech man sounds extremely baked aha great video bud
Baked like a brownie. Thanks for watchin.
Can you put togeather a gatherinf
Probably but then all the motorheads will be jealous and start hating first me then you once they figure out you gave me the idea unless you want to pay for it in that case it's $1000 up front for parts and labor -- $350 for aggervation and idiocy issues -- $250 for incendental expenses for beer and tacos from del taco -- $50 per call for support and troubleshooting the electrical system -- $500 for speciality tools and diagrams of the prototype engine -- $70 for new work boots -- and you cover the paint / powder coating up to $175.
After all that is paid I draw up the plans and start building the whatchamacallit for the altanator and I send you couple pictures next week of the progress on the 24pak of Miller's
Yeah what your say'n is this.First you take that little 48 cc off the frame take it apart get your rat tale file widen the intake port and exhaust port just shy of the edge of the casting on the chrome side leave the cheese behide that unless your attaching a reed valve if so check it for clearance.With that done continue on to the transfers trim the to a near sharp edge work that angle an inch or two toward the windows and then bevel or radius the windows all way round that's it. Reassemble it and now you have it ported correctly, perfectly wonderfully magnificent now let it sit there and wonder why did I do that to my nice little 48 cc engine ?
I would use a dremel with a metal cutting bit myself but I didn't port this engine the ports were pretty clean when I got it so all I did was use some emery paper on them and polished the surfaces for better flow") so why did you do all that stuff anyway arthur?
These engines are all about the same you need a reed valve and the intake and exhaust ports have got to go wider than factory I didn't touch the height on them but and I've got a GT 5 cylinder head as well much larger combustion chamber running strong in dry weather when it's rainy not as powerful but compared to factory 3x the torque 2x the RPM range..
sounds like you been working on a new engine set up arthur made any new videos lately?
+arthur clark I have a lot of questions about 2 strokes and you seem to be very knowledgeable about them. Could you teach me a few ways to increase the performance on an 80cc 2-stroke?
ForRealBruh 01 what u want to know Arthur? u already milled the motor and stuff the rest is gearing and jetting the carb that my friend is in experience ")
would it increase speed if you use a lawnmower spark plug?
Know im saying 🤣😂, reminds me of were the millers movie
Yes, I know what you are saying.
are you going to ride over to the farm now? thanks for watching
I wouldn't go with a longer intake because the engine has to work harder to get the air through that so if you have that like 3 inch intake right there and you were to blow through that and then you go to a 6 inch air intake and blow through that the 6 inch air intake you will have more resistance and if you want performance you want that fuel mixture to get into the motor as quick and fast as possible for the high revs
theory here is to get a bigger charge of air/fuel mix and by increasing the intake runner it does this just by having that extra 10% in the tube all the time. if you go to long like you have said then you are running into a different set of problems that include flooding and excessive oil in the cylinder because you have to much air/fuel mix in the intake all the time this is why I recommend in the video to try to stay inside of the 3 inch length that I have on my engine. this allows the air/fuel mix to stay constant and it doesn't make the little piston work so hard sucking in the air/fuel mix. Plus if you add the expansion chamber and skirt the piston to increase the flow from the interior ports then the whole thing works together to increase the power of the little engine. I only eluded to 6 inches if you were to do all the extras like porting and adding the cylinder head and that stuff. thanks for your comments that put some more light on this subject and just might help someone out that needs a wider explanation") thanks for watching
+brian noel thanks for making it clear I've never bought any mods for my motor I've always made them and right now my two-stroke motor bike is pushing around 13 hp and I've got a expansion chamber that I made and right now I'm building a custom head for it
you my new friend are the reason I do all of this stuff") guys like you that take what it is and do more with it are the corner stones of the whole motorized bike world. I am only a small book of knowledge that deals with the stock engine that everybody starts with") why haven't you made any videos of your bike? sounds like a ripper that needs to see the light on youtube")thanks for you input it matters
+brian noel I've just been to busy with with work I'm 16 and I own my own lawn care business's Plus I race my friends out there and I haven't told anyone the mods I do on the inside of the engine anything like that because I'm the fastest one out there and I want to keep it that way
+brian noel you should look up the two-stroke tuner book it will help you a lot you can buy it or you can look it up on the Internet but it's definitely worth it if you want to fine tune your engine
