10,200 MPH!!! Hold on there boys.
Yeeeeee Heeeee
Rpm*
Ain't that fast there Timmy
That camera view from behing the headlight hole was killer John.
Your camera work has gotten awesome over the years.
360 cameras rule
John is the brains behind this production
@@Philc231The computer side of it probably. Not the building side of things 😂
@@contraband1543 he's a pretty solid rider as well though. When Ike was worried to ride one of the bikes a little while ago John was like yeehawwwwee
Thank you! Worked out perfect this time
I just finished a landspeed project, and learned that changing sprockets by just one or two teeth can make or break your speed wildly
1 tooth up front is about 3 teeth in the rear. I still like running as big a sprocket up front for less drag on the chain bending the corner
That fairing pairs perfectly with that 360 camera! Great job.
yeah it's exactly perfect for that kind of filming. fantastic for showing the speed from a great perspective
You guys are still in small group of people to go over 90 on a minibike. I consider that test day a success.
At 1.46 minutes in:
That engine’s power peak is 10,200 miles per hour?
Great Scott!
🤣
Aerodynamic drag increases with the square of the velocity.
Which is why that top end gearing is so critical.
steve
At 1:50 John said "it's full speed @ 10,200 MILES PER HOUR....I hope you meant 10,2000 RPM.......10,000 MPH is damn fast....
Lol .. great correction. "I hope you meant 10,2000 RPM". Maybe stick to easy comments.
I was just about to comment the same thing. That's so funny 😂 must have been a late night for them...
@@g-force2745 Some people =))
shout out to Washington Warren Airfield!!! thats a really awesomely kind gesture to offer the airstrip!! 🇺🇸🇺🇸🇺🇸💯😎😎
The 360 camera location was so awesome
I love how much this channel has grown. I remember watching when Ike flipped the lawnmower y’all made or the Ducati go cart trying to go fast all the way back then. Seeing where yall are now makes me super happy building new things to try new speeds!
Looking good guys! Focus on aerodynamics, tyres and gearing and you'll be golden. I think changing to rear sets would be a big help, being curled up with forward facing controls is creating a bit of a parachute effect.
So for the balancing part...there is a yellow dot on the side wall where thr valve stem should be so the tire would be nearly perfect balance
I came here looking for this comment. Thank you in glad I'm not the only one that seen that. Yellow mark is the natural balance point.
yeah, and the yellow dot was oppisite the valve, which shows why it should be by the valve.
I’m loving the land speed and the drag racing cars. I’ve never seen anyone build a trials mini bike I think that would be super cool and fun. Slow a lot of torque , no seat etc
We are ALL learning, watching you guys.
I thoroughly enjoyed this video. Thanks. I love the small displacement engines and the fact that in comparison to some of your videos, this was relatively safe, even with the speed.
Just be careful guys. That's cookin for a minibike it's really great to watch and I would love to keep watching. I don't want you guys to be hurt. Thanks for sharing and I'll see you soon in the next one.
Grind off the tire nobbs and make them slicks. Saves moving weight and rolling resistance. Total bike weight doesn't do much for top speed, only acceleration so for land speed it doesn't really matter, adding weight with a big fairing could therefore be a win as wind resistance has way more effect.
It's awesome that Washington Airport let's you guys use the strip never seen a Minnie 🚲 bike go so fast before 😁👍
Wow it's crazy to see how far u guys have come over the year
Hard work and a supportive community!
The "Heavy Spot" on the front wheel is the VALVE STEM, you have the yellow Circle printed on the tire which is the LIGHTEST part of the tire which is supposed to be mounted on the rim by the valve stem, you have it 180 degrees away which is exactly the opposite of what it needs- You should have let the air out and popped the tire off the bead of the rim and clocked it, and you MAY have needed no weight
I was yelling at my phone when John was riding feed it John just feed it 😂😂 can definitely see that Ike has no fear he was flat stick the whole time
Because the gear was so short. It would have blown up if he just valve floated it the whole way down the runway,
Try and incorporate leg/knee baffles to help get the air around your legs on the next build, as in you can tuck your legs into the fairing
that 360 cam work was sick
That was a joy to watch. Need to get the gopro app and add a sticker to show your mph.
Everyone who said the other bike was too heavy, this bike is slower with twice the horsepower and half the weight.
Goes to prove me correct that drag is everything at these speeds.
Yea, above 60 the wind drag, front and rear, gets multiplied more and more as the speed increases. Just sticking your elbows out can cost 5mph. Years ago I could get 70 out of my Yamaha RD50, mostly by eliminating drag. They also need a 6 stone test pilot.
In my '88 MR2, I could be going 140mph and pop up the headlights or vent the sunroof, and I couldn't push past 125
This video feels like the old original content when yall first started with just you two knuckleheads... cant believe yall have come so far... and have inspired me to even start filming and learning to make content... love watching you fellas and the itll be fine attitude of squint if its mint
The yellow dot on the side of the tire should be placed where the valve stem is for better balance
I would like to suggest putting foot pegs further back on the megamoto near the back wheel so your kinda laying down and able to have better aerodynamics with the body stretched out.
When homie said where this thing is warming up most things are topping out I could just see the pride in his face that was awesome 💯
Great job boys! I have a blast watching the 3 of you and your crew!
It's definitely a worthwhile project. Good for California, and I am from Texas, but I love you guys, and you outta crush them real good. Keep this project going and blow the doors off those other guys!
Great video guys 👍. Y'all are so close to the 💯. Ike really enjoyed talking to you at the Drone Expo Saturday❤. A lot were interested in the carts. This Old Man from Washington NC always enjoying your videos 🛵🧔💝💝💝
G'Day from Australia. I finally caught up with your years of videos. Just my perception but its the fun racing that appeals the most. You need to do more vids on people having fun chasing each other on the racetracks. Its the best vids you have.
That yellow circle on the sidewall is supposed to correspond with the valve stem enabling easier balancing
would love to see ike use that track suit and get a cheap r3 or ninja 400 and rock out some laps on a track for something different. Would be neat to see you guys all do it honestly and watch the progress and the adventure!
I'd like to see them go for a land speed record on a Ninja 400. And have Ike wear his muffin top leathers. That would hit a million views in a few days.
Definitely needing some aerodynamic fairing on the front end to fight the wind resistance . Is there any chance for a more skinny tire . Very impressive guys .
A half fairing would put them into another class.
I think the angle the carb is sitting at is losing you guys hp at high speed. The wind is pulling air out of the carb as it is rushing by.
When I was a kid I had velocity stacks on a cb750, at wot I could spread my knees away from the motor and gain big power compared to squeezing the bike with my knees. The latter caused the air flow to cause a vacuum at the stacks.
@chuckfry1227 Same deal with my GS450, if I spread my legs a touch at 85+ it makes a noticeable difference.
How the fuck did you even think about that
Ram Air intake ?
@@chuckfry1227
I also owned a Nighthawk (CB700 instead) and noticed strange air effects when moving my legs in or out at speed. There was something weird about the intake flow on those bikes.
id actually be quite interested to see an episode where you had Russell show us about some of his projects, i think that would be quite interesting
Im only a minute and well 1:26 in is where im at and i must say boys, this is the best looking ride y'all have built yet!
Ive been with the channel since i believe later part of 2017 and i enjoy your stuff so much. Y'all keep me going on my own stuff just because of your clean enthusiasm...if that makes sense!
Really like the new lettering for your thumbnails, looks really slick. Content is phenomenal as usual, y'all are doing great.
Man, that little bike is freaking awesome!
I love those tire, balancing things that you guys have there! I got to get that for my auto shop lol
When you guys mount your tire's up try to put them on so that the paint dots on the side of the tire are next to the valve stem. It should help with balancing the wheels.
You'll get it there, no doubt in my mind.
i like how the front tire turns when reving it on the lift
The writer suit can be aerodynamically altered to make it as slip stream as possible with helmet and back fins to close up the air at the back. Good job guys! My mini bike back in 1969 could never have done that😂
Too much tire resistance. Slicks man !
I'm surprised you didn't block off the headlight opening. For gearing, remember to take tire growth into your calculations.
Sweet camera work!
Good video guys keep up the good work and break the record
Hi guys. You have great content and I never miss your videos. Just wanted to let you know that the yellow dot on the tire it’s supposed to match the filler plug for better balance. Hope that helps.
Nice work guys! The shot through the headlight opening was cool. If you can get your feet all the way to the engine with the knees in. A wedge diverted on the front of the frame and out t cover the legs, and a front fender will help.
Love you guys and your content it feels amazing to be able to grow up with you guys on TH-cam
This project is very interesting. Keep making it better guys!
This channel is always a joy to watch, been subscribed for years. Keep up the good work and it’s great to see you guys enjoying what you do
I love the look of the new product. Reminds me of a Baby Bull.
With the amount of tire growth I'm not surprised the gear ratio calculations were off by a bit. That tire grows quite a lot.
Yup
I have faith in yall, yall will get there. Its gonna be tough, but its not far out of reach. I built a bike and engine for someone awhile back and let me tell you it was tough hitting 60mph. The engine was a stage 3 212, all off the shelf parts which claimed 22+ hp. Idk if thats our end result or not. It had a big aftermarket Mikuni on it built and tuned by me. The frame was a junk Coleman frame that we built as best as possible, with whats available in the aftermarket world. We had 4 or 5 diffrent gear sets. We ran it on Shell V-Power 93 octane pump gas. I can tell you, the built engine was rowdy, but with a 200lbs man on it i think the fastest we ever went was 57mph. I couldnt imagine trying to hit 100+ even with the big boy 236cc. Like you said power and weight isnt everything, you gotta be able to slice through the air resistance with the least amout of drag as possible. I know yall will get there, we will be watching!!
Well, you're worried about the rear tire growing too much, so go to a a slightly shorter rear tire and see how that helps in gearing.
It's crazy to see your guy's channel this big now. I remember years ago seeing you guys in a shed getting a thousand followers. Keep up the great work. 👍
Its good news that the frame checks out and rides smooth. I guess its just a matter of finding the sweet spot on gear ratio. I thought sure we'd hit 100mph on this run. Thanks for bringing us along. Watching the trials and errors is good content. Heck, when something goes wrong we're just as bummed out as you are.....but when it goes right.....we're celebrating right along with ya. True story! Great job guys.
Yeah buddy, nice work fellas!!
yeah you had it geared for 120 with that tire size but if it grows 2" thats like 132mph
Hey for future reference… the yellow dot on tire is suppose to be lined up with valve stem for balancing purposes
TVR updates would be awesome! Great video.
I did some calculations for you.
Assuming overall tire growth, 10,000 rpm and a speed of 111 mph.
I know you have a 11 and 13 tooth gear.
The gear ratio I came up with is either 11/65 or 13/77
Without taking consideration of tire growth the ratios came out to
11/56 or 13/67.
Tire growth was estimated at 1.5 in increase in radius.
Personally, i feel a 13/72 gear combination would guarantee a triple digit speed, probably about 105mph.
Get rid of the street tire and go with a slick and has anyone ever looked at the spark plug ? the plug can make a big difference in top end. What weight oil are they running in the engine? That is something else to look at as well. Nice job on figuring out the tire growth.
Great test run on the bike! Gotta say that Chevette you use as a backdrop would be mighty sweet rolling down the road!
Great job guys 👍👍
I think better tires would help alot. And if the tire is expanding at speed it could be rubbing just enough to drag and effect the top speed. But its really cool! You guys will probably get to 120. Good deal!
Great video guys. Thank you
Hey John a huge improvement to your production would be to put microphones on everyone. Watch an episode of Bad Chad. You can hear every word from every person in the shop.
Yep, wireless lapel mics will make a huge improvement and they are comfortable to wear.
Agreed. You're getting very professional on the concept, planning, builds and tests.
Id love to see real time telemetry on the screen
I love the mental battles between optimism and practicality before each run. Lol. It's just a test. Yeah s test of 110 mph
you guys have the space for one of those 2 speed centrifugal jackshafts in there, one of those seems like it would be perfect
Cool video, when you boys mounted the tire to the wheel you should have put the yellow dot where the valve stem is.
Love the vids!
Great camera shots in the nose fairing!
Are you accounting for the tire growth when running the numbers for top speed gearing?
Keep up the good vids! 👍
great stuff guys thanks
Can’t believe I was like 12 watching youse back in the day still watching now. First video I saw is 10 reasons to buy a cheap kart
My dad met y’all today at busco talk are really chill people keep up the content
TVR Tuscan! Nice!
Awesome guys! Y'all be safe out there and don't get into too much trouble with this thing 😂
I love the racing stuff
I’m impressed with Ike’s cahons 😂😂 no fear
Hey Ike ,just wanted to ask you at least 1 more time how’d it handle 😂, I think John asked 3-4 times ,that’s a good looking bike and you can tell it’s pretty smooth with the camera views hardly even shaking at all , great work guys 🤙🏼
Ditch the big meats run the small slicks, lot of rolling resistance pulling the heavy meats. Your lowering bike fixing tire rub at the same time. Narrow bars and hunch back leathers will help with the slipstream the back of the bike. Awesome job on the build guys.
Only 1 min in and already wondering how those 62 mile an hour rated tires are going to hold up going twice as fast?🤔🤔🤔
Speed rating requires withstanding at least 30 minutes at that rated speed.
After that tire integrity is not implied or promised. That's why tires on vehicles that go really fast need to be replaced after hitting rated speeds or higher. Check it out, how tires are rated is actually kind of interesting, if you're into stuff like that. But given you asked this question, I bet you find it interesting 😎
@@goosenotmaverick1156 THNX capt. DOT
Why would these guys choose a knobby, wide, heavy, off-road tire for a high-speed run? I often wonder if they do these things for ratings or if they are unsure of racing physics?
@@larrycarlston4044It might be difficult to find the kind of tires you want in these sizes.
@@larrycarlston4044They're just spitballing. I don't see much research being talked about. It gets frustrating at times as a viewer, but when you're on a one week schedule for videos it's also hard to keep working on the same bike and keep it interesting and keep the views and hype up. If they made it perfect no one would watch and I understand that because perfect is tedious and tedious isnt fun to watch.
Do you guys Change the oil every time you run the bike as you should when running methanol? Also a good idea the run the engine on gasoline after each run to get the engine up to temp which will help remove the corrosive methanol from the crankcase. Methanol eats valve springs while the engine sits if you don't change oil enough.
Looking good. It will hit the goal before you know it. Y’all are a good group to represent NC!!! I’m NC born and raised. Greensboro area
Good job you will get it
I'm wearing a shirt that looks a lot like the one Ike was wearing while driving. Cool coincidence. Farout man! lol.
NOSE CONE CAM!!!!!
Can't wait to see that shot at 100 MPH plus.
Definitely need to figure out one sprocket at a time boys but this was real cool
MM77 Approved 👍🏼👍🏼…………………………………………………………The camera view out the headlight hole in the faring was pretty cool.
Gonna be epic!!!
Russel has a TVR?!?!? OMG God!!! Heck YEAUH!!!
You guys should consider doing circles at the end of the runway to spool the bike up to speed. Go as fast as you can before you lose traction, then bullet down the track for a run. I bet it’d break 110 with this approach.
I'm so hyped 🎉
Awesome video
