The RC Aircraft guy was correct to a point.
What you're looking for is Venturi Effect cooling through the entire bay. The bike was originally designed for combination cooling of a radiator AND air cooling over the entire engine assembly, so even if all the cowling is totally removed, if the engine assembly is sitting in a static air pocket, cooling is diminished. The outflow needs to be increased and the overall engine bay airflow needs to be upped.
You might look at the feasibility of fabricating an underbelly airscoop to increase frontal bay flow, not just radiator airflow. Then look at a pair of small rads, such as Sportster or Spyder RT units with the intakes fully ducted and mounted directly at the body side air intakes so as to remove the flow obstruction at the front of the engine assembly.
As for my experience, I've been a biker for over 60 years and was a National Bureau of Standards Lab Rat who worked in the Physical Dimensional Laboratory, doing a lot of work with Fluid Dynamics, which puts this in my Ball Park.
I really want to see you guys succeed with this beast, and I look forward to seeing you get all the bugs worked out of it.
I have done a lot of R/C flying since I was a kid and the rule of thumb was the exit should be double the intake.
@@craigwright5585 That's true, but from my experience in the Lab, the flow path is just as important. You have to look at the cumulative flow rate and path, not just the intake and exhaust volumes. I'd love to get into your rig with a few temp sensors and flow gages to see what the interior flow rates and point temps run at around the drive train.
@@WilliamEades_Frostbite Agreed!! It never seemed to be overly crucial when it came to R/C, but the odd time baffles would need to be added to direct the airflow, not unlike full size aircraft.
He's right. I expected the fan to do nothing. It isn't helping much if at all because it has no place to draw cool air from. The intake side is blocked.
@@craigwright5585 My point exactly. I spent a good bit of time last night thinking about the bike's design. If you look at the bike as an aircraft fuselage and think about the planar flow paths, what came to mind was that since cooling becomes less efficient as speeds increase, you're looking at flow stall along the sides of the bike. Where the intakes sit are very likely ending up in a low pressure zone created by the stalled air zone rising up off the side wheel sponsons wing root as your speed rises.
I came up with 2 possible options. Both involve glass work at the wing root leading edge.
One is an intake scoop above the root, and if you want to keep the overall design of the bike intact, place the scoop below the root like on an F111.
To test the theory, you could use inexpensive AC or Dryer ducts taped and zip tied in place so their openings are right at the root leading edge.
You could use the old "Tape and Yarn" trick with someone driving beside you videoing the bike as you increase speed to see exactly what the airflow does and work from there.
Craigs not just your mechanic, he is like the other half of Martin & Lewis. That is one of the best videos you have done in a long time.
Craig reminds me of the "Wizard" from hoovies garage haha
Martin and Lewis? More like Pinkie and the Brain
Craig is Brain
28:33 I just noticed the side mirrors taped to the shoes 😂
YIN/YANG kind thang... ;)
Dude, in 2007, My friends and I, cruised to fern cliff ,Gorville Illinois, and an old man was cruising exactly what you have here, he stopped let us all check it out, and invited us to follow him home to Goreville where he treated us to a view of his 1934 Harley Davison, it was immaculate, he was 93 years old, thumbs up Great video
He sounds like the coolest guy in the world. How trusting and friendly of him. I love old people !
Cool, I live in Goreville
92? Damn, that dude stole the Ponce De Lion cups from Jack Sparrow, for sure, and been using it hardcore mode ever since!
I love how honest the seller was. Can't accuse him of glossing over ANYTHING.
He just biught it back from him
👍😎👍
I noticed that too. Good stuff
Its supposed to fly right. Probably best to inform somebody of any potentiality of problems rather than just making a sale unless you just dgaf
1. Airflow Dynamics: Air expands slightly as it heats up while passing through the radiator. A larger exit hole accommodates this expansion and ensures that the air can escape without creating excessive resistance.
2. Pressure Differential: A larger exit hole can help create a slight pressure differential that encourages the air to move through the radiator more efficiently, aiding in better heat dissipation.
3. Preventing Turbulence: A larger exit helps reduce the risk of turbulent airflow that could otherwise reduce the effectiveness of the radiator by creating uneven cooling patterns.
In summary, having the exit hole slightly larger than the intake hole is generally a good practice for maintaining efficient airflow and cooling performance in a closed system.
I think I'd just make sure that the air was blowing through the radiator. Possibly with a thermostatically controlled fan to help from time to time.

I owned a Pulse for about 3 years. I installed a Kawasaki 750 zx 7 motor. Plenty of power. I mounted the original radiator up in the under side of the nose with a scoop. Never over heated. Every Pulse I saw with the Gold wing engine had the radiator mounted outside on the side of the body in a housing. They never overheated. I never saw a vehicle that attracted so much attention. People would follow me home just to see what it was. I sold it because it wasn't really a practical vehicle for everyday use.
wow thats awesome that you had one. send pics
@@BikesandBeardsMy Kandi go-kart has a small radiator with a fan that turns on by a thermostat when temps get high enough. I noticed the newer Go-karts they're producing no longer even have a radiator at all, but an OIL COOLER! Does the job well enough to omit the radiator!! Something to think about and consider maybe for extra cooking. I put a pretty chrome tubular V shape oil cooler on the front of the down tubes of my Harley Davidson frame and it works great. The V shape is stylish and fits with the flow of the bike.. It might look right at home on your deathtrap machine. 🤣🤷🤷
Also, I think a person can buy those small radiators with the fan that's attached. Would be easy to adapt to your 'Deathtrap Machine.' That's my official moniker I've given for it. 😂
I don't know though? $49 might be exceeding your budget? 🤣🤣🤷🤷
@@johnathanhurd3561 Bro, you are not that guy pal
22:42 i CANNOT believe that nobody said "yeah on the other side" lmao! So wholesome to see Sean and Craig wrenching together again!!
My buddy in early 80s bought a red one of these. We took it for a spin one night after church, cruising with Phil Collins' "In the air tonight" blasting over the screaming Yamaha engine behind my seat. Sketchy ride, but an exhilarating and surreal moment.
I just did the drum breakdown at my desk.
I am one of the grandsons of James Bede, the creator. He always talked about redesigning the chassis and using a higher hp motorcycle engine. He has passed, but would have loved to see this! I have been around many of these and also love this idea!
I am sure you know, but the Pulse owners get together over Labor Day weekend in Indiana
Now that I read that James Bede was the designer it makes total sense.
Jim Bede was such a visionary.. and ahead of his time.
FWIW: I was thinking _Jim Bede_ was the designer for these things.
Thanks for confirming it...👍
Jim was a visionary. I was a teenager, bought a used BD-5 kit and built it back in the 80's. After going for a "check ride" with a CFI to see how I liked flying, I realized I didn't, and couldn't. Sold the BD-5 to a restaurant owner who wanted to hang it up inside. Now this Pulse.... that would be just my style. a GROUND based BD-5 lol 👍👍
@@kyleb3754Sagebrush Cantina?
This is the most honest seller I love it.He basically told you that this is a death-trap and you probably shouldn't buy it. LMAO!
Maybe they have those disclosure laws there.
I think the bicycle guy was right. A bigger air outlet than the inlet would create a vacuum, making a suction effect and thereby increased airflow.
Nothing to doo with vacuum. Hot air expands, you need a bigger outlet to flow as much mass out as is flowing in. If your inlet and outlet are the same area, your inlet is too big, which is very important in air-cooled aircraft engines, where a smaller intake means less drag.
I don't think having a larger air exhaust would create a vacuum. it would need something forcing the air out to do that and the only thing creating pressure would be the intake. The smaller exhaust would limit the air flow though.
@@Mariano.Bernackithere isnt alot of expansion between 20C and 30C
@@adammcloon9367yes, faster air create low pressure. The same principale make plane fly, racecar stick to the ground, carburator work and increase horsepower with a better exhaust.
she needs a jet exhaust for this beast of a jet :)
I'm an RC pilot; the guy was right. Outflow vents needs to be larger. Otherwise the Electronic Speed Controller overheats; the battery overheats, then the battery vents with fire. However, I'd guess the radiator isn't getting airflow THROUGH it.
Correct. It doesn't help much if the airflow goes behind the radiator, especially with a smaller outlet. If it was bigger, then it would help with pulling the air through radiator, but the wall right in front of it doesn't allow it.
Mount a Taurus electric radiator fan on the back side of the radiator with on off switch on the dash. Two vents in front of the radiator instead of behind it would help.
its a water cooled engine so get the radiator working out in the fresh cool air, its clearly blocked by the seats etc and just sitting in a stale air bubble.
I see you also passed second grade. I was literally face palming that so many grown adults in the automobile sector had no clue. Seeing this would make me afraid to ever let them work on a vehicle I was going to trust my life to not go up in flames.
The guy on the bicycle was absolutely right about the outlet! However the best solution would to ditch that radiator and go with 2 separate slightly smaller radiators mounted right at the opening of those air inlets. In addition to this you could add a small oil cooler anywhere it would get airflow. The other option is to mount a radiator on the undercarriage with a small airdam feeding it. Although the twin radiators on the inlets would be easiest along with small electric fans.
put another radiator in the nose where you can feed air directly through it. The one in there can handle idle engine, so just need one for higher revs.
Also OIL Cooler. Remove extra heat through the oil. Got out of a ticket driving on the shoulder. Told cop I was overheating, and bike was pinging, hissing, and groaning for me.
No the best solution is actually putting air THROUGH the radiator because that is how they work.
AKA the "Pulse Lightstar". Designed by Jim Bede. I have 2 aircraft designed by Jim. A BD-5 and a Grumman Yankee. Jim passed a few yrs ago, but his family still tinkers with them around Akron, Ohio. I visited them a couple yrs ago.
Btw,..the bicycle riding guy was correct about the exhaust air size. Ideally it needs to be able to exit as much, if more than, what comes in. But cooling has been a recurring problem with Bede designs.
First off let me say you helping the lady is the reason I subbed. You are a genuine person. Take care and God bless.
Worked on one of these in Elgin, IL when I was a bike mechanic during college. They are the hardest thing to work on, and good luck finding parts. They are fun and eye catching though. As for the radiator issues, use the R1250GS radiators and put them in the vent positions themselves.
Also, I live 40 minutes from you in TN and would be glad to come help.
I would use GL1800 radiator and fan assemblies in the vent locations.
That cycle is amazing! Get the cooling issue sorted. Paint it like a Blue Angels or Military Jet!
Could even add a BB Minigun to the front side of the cockpit! Lol.
Air soft might be a safer option,and really cool.
Stop trying to manage the airflow inside - reposition the radiator to where the air is already freely flowing. Out to the side or in the front, but leave the new scoops and direct that airflow over the engine. And redesign the exit holes and the vent slats. Motorcycles position the radiator so it gets a lot of airflow, but this vehicle hid the radiator and cut undersized and ill-positioned side vents, and was guided by aesthetics in designing the exit holes.
Attach radiators to both sides and equip them with fans. Similar to the Honda VTR 1000 Superhawk. BTW: If your support wheels fall off on the highway, nothing will happen at first. Then a motorcycle WITH support wheels becomes a motorcycle WITHOUT support wheels. The gyroscopic forces of the two wheels on the vehicle's axle provide the same stabilization as any other motorcycle. You only fall over when you stop.
So the vent in question on the side is a variant of a NACA duct, designed to create a low pressure zone forcing higher ambient air into a volume. Having the radiator at least at an oblique angle would serve you better than a glancing blow, but more importantly (or as important), routing the air out the bottom behind the rad into the airstream between vehicle and road will help create more airflow 'ramming' in. Two smaller rads you can place in the airstream would be the ideal situation.
Add: Almost forgot, the duct you guys added on the side more hindered the function of the NACA duct than helped, as it doesn't work like a scoop. It is totally reliant on air passing over it and the shape of the inlet.
Two grown up kids having fun. Life doesn't get any better
IMHO, the cooling issue is caused by the radiator not being in the airflow. It appears to be located in the same spot as a stock GSXR and has the hot exhaust underneath. That’s fine when the only obstruction is normally the front wheel and fender (which actually works as an airfoil directing cooling air into the radiator) but when it is now behind the firewall of the rear seat, you have no airflow. Your solutions need to be to either direct air onto the radiator by either pulling it in with more complex ducting and fans or the easier solution is to make a split radiator system with one on either side of the engine (think Honda VTR / RC51 / or VFR800) and place those radiators into the airflow you already have with the ducting you modified already. You’re going to need some good sized radiators as it’s a big engine but it’s totally doable and would give you something you can use even in daily traffic. If you really want to get crazy, put the radiators in the wing roots or in the nose (with appropriate openings cut) where there is good high pressure zones to force the airflow through them. Anyway, it looks like a ton of fun!
Easily the best solution. Now it's a hot air intake for real
I don't know much about motorcycles, but couldn't this be a thermostat not opening or a dead water pump? Or even air pockets? It sounds to me like perhaps the coolant isn't moving... So it doesn't matter how much air you put over the radiator.
@robertstahl8835 if there was no circulation it would be getting a lot hotter. It's definitely an airflow issue
Gl1800 radiators and fan assemblies. Easy
Split rad each side would do it nicely
The person that said the air out has to be bigger than air in is 100% correct otherwise as you ram air in it pressurizes the space instead of flowing through creating A "Dead air space" that prevents even new air from coming into the engine space due to the pressure. For an example take a 1l bottle poke a 1/2 inch hole in the bottom and blow as hard as you want through the top and see how much flow you have and how much pressure you have. (Flow good for cooling pressure bad) even on that 1l bottle a 1-1 inlet to outlet hole size will build up pressure as you blow into it. There is much much more to the subject but that is the simple example.
I would love to see you fabricate two big scoops similar to the harrier jump jet for the cooling system. The position of your air intake is your biggest problem it needs to be nearly a foot further forward. Delete the rear seat and move the firewall forward as it is your biggest obstruction of your airflow, move the intake scoops forward, swap out the radiator for something bigger rotate it so it runs linear with the bike and duct the scoops so they aim in toward it.
Looks like something you would see in front of a Kroger that requires quarters.

As someone who runs a GSXR1000 motor in my dirt track car a lot of us still use the factory clutch lever and just mount it to the shifting handle like what is setup here. To prevent over heating we also run a small car radiator on the back deck to keep temps down below 205 even after mid summer races with rpms staying at 12k-14k.
The Pulse was built in Owosso, Michigan and name changed to Owosso Motor Car Co. The original Pulse had Yamaha's air cooled engines but had cooling problems and switched to water cooled engines.. The Pulse was it one of the Back to the Future movie..
They had a couple seconds from Back to the Future at the beginning of the video showing the.... motorcycle...
made one block from where i live...Ed Butcher was the designer
If your air exhaust opening is larger than the inlet, you create a low-pressure area in the rear that will increase airflow through the space, actually sucking air through it, in the same an exhaust augmenter works on an airplane engine exhaust system.

Your buddy smiling when riding and saying "I want to keep going"...man Craig what a man! Good job at least riding it off the mark and doing it well!
I would suggest wrapping the exhaust pipe with titanium exhaust wrap. Will keep the heat down in the enclosed engine bay A LOT. I don't know if it will help the overheating issues but it will definitely help a whole heck of a lot.
You might also be able to get a small electric fan and mount it in front of the radiator, blowing air through it.

The cooling is maybe simpler than you think. You can move the radiator itself to another place. Yes, remove the fluid, length the hoses, refill. But then you have severa options for it. Use 2 smaller radiators, one on each intake hole. or move the radiator "under" the floor, so it will get straight wind.
Or make a new hole in the underbody with a 3rd scoop, and put a funnel-hose straight to the rad, and let the side ones cool the rest of the engine.
IF you have to do another Motorcycle swap for that GSX, try to use an old Honda Goldwing. These have reverse gears and a nice flat 4 / 6, depending on the year of build.
Or just add a fan
@@16driver16 electric Fans are NOT the same as air flow at top speeds. been there done that.
@@popeyedog not all fans are equal... you gotta spend good money on a very strong one and wiring for the power it takes
We did that with our golf kart build put the radiator way in the front with the longest hoses and it worked out
Honda Goldwings don’t have a “reverse gear”. The starter is run in reverse with the bike in gear.
Bearded man in a weird little motorcycle thing. Love it.
I built a Pulse from the last "kit" that Owasso Motors sold, as they were going out of business. I used my 1200 Goldwing which is water cooled, and still there wasn't enough cooling. The glass windshield is irreplaceable, and the canopy slides break easily. Yours is the first iteration with the 1100 air cooled, and a tail fin. Later versions used water cooled bikes and lost the rear fin.... as shown in Back To The Future. The most dangerous part is that the side trailer tires don't ride on the ground. At highway speed turns, those tires must go from 0 to high speed, which throws the whole thing off balance. I lowered my side wheels, but it wasn't the same fun after that.
Klasse, daß es die automatische Übersetzung gibt. So kann man es easy auch auf deutsch anhören.
Yeah! 👍
You need tons of vents at the rear for the hot air to escape.. you have trapped all the hot air inside the structure.. Think about how a motorcycle works..its open everywhere.. air is rushing by and taking away the heat.. you have stopped all the air from flowing past and taking away heat.. and there is nowhere for the now hot air to escape.. Looks like you got the clutch going.. I saw you were addressing it but I must ,have missed the part where you say if the repairs worked. very cool action. cant wait to see the ride home.

Cool air to rad heats up and expands. Bigger exit keeps the pressure even. Ta-Da.Better overall flow.

Lol both the wings about to fall off. Now I see why that guy gave you that look when you mentioned you wanted to drive it all the way back haha lol.
Thanks for panning over to the kei truck. I thought I did that with my mind lol.
Dual radiators(smaller than stock) directly mounted to the intakes, in addition to a fan to push across the motor while pulling air in through the radiators.(rear ducts of radiators)
Bigger out than in changes the pressure dynamics, expanding gases is the heat exchanger effect, so if it exits at a lower pressure than it enters it will pull out more heat as it goes past. Just like how a compressor in an air con or refrigerator works.
Craig, if something goes into your ear, the worst thing you can do is jam your finger into your ear to possibly push it down farther. Just push into your ear from the outside. That's your safest bet
🟦…"push into your ear from the outside",... Isn't that what he already DID?
LMFAO the montage of workingmen with the chick climbing the mountain lol that’s perfect😂
6:58 ok so *nobody* is going to mention this??!😂😂😂
It was so funny. You mentioned learning the drive of 4-speed and worried about rolling back on a hill with a car behind you. It brought back memories to me that Volkswagen van I had purchased from a friend and never driven a four-speed before and I was terrified on the first Hill. I stopped on and subsequent ones for a while. A great memory to bring back though
Craig is so amazing! I love watching his channel too. He seems to be a great friend/brother!
Great seeing you two together again. Hope to see more

Experimental aircraft builders learned that adding an exterior scoop to a NACA duct (as seen on the side of the Pulse) does little to improve airflow but does add drag. Rather than increasing the airflow that's missing the radiator, it would be better to push the air through the radiator. Maybe a belly scoop ducted to the radiator with little to no sneak path around the radiator, or put a small radiator on each side NACA scoop, or add an oil cooler plumbed at the oil filter.
Need to build some radiator pods like an F1 car… fit right in

Guys, why not just move the radiator elsewhere, so it is constantly exposed to airflow? The fan is pointless if the vents push air against the flow

A larger rear opening causes a cavitation zone and a vacuum to draw air through, in rc it helps draw the air around the jet out not just allowing the jet stream through...
Can I get a ride in that joker or what
This channel and these videos always leave me with a smile on my face. Thank you, gentlemen!
Glad you enjoy it!
Should move the gas tank up front and open those ports larger. And just having a gaping hole in rear isn't the same as tubed /ducted exhaust. Especially when things around are not rounded and symmetrical. You can't take the fan shroud off the fan of a car and expect it to cool if the radiator. It's why is there, ducted cooling
intake valves are bigger because during intake cycle you have much lower delta p compared to exhaust cycle, you have massive overpressure post combustion = less cross section needed to evacuate flue gasses.
You draw cold air in and run it through radiator => it gets hotter and expands and now needs larger hole to get out of than it needed getting in
Think of air as like water if your outlet is not at least the same size as your inlet you will overflow. So having a bigger air outlet will allow the air to flow through more quickly pulling more heat from the radiator at the same time.
The guy on the bike may have been talking about airplane baffle design where you want a certain pressure difference across the cooling fins to ensure you get the proper airflow across the fins to cool the engine. Some have cowl flaps that opens the aft section where the air exits the plane to increase airflow through the cooling fins during high power low speed operations such as takeoff and climb. The system in your bike is setup different and it sounds like the air from the NACA ducts isn’t even going to the radiator at all and the air path isn’t sealed so all of the air must pass through the radiator.
Very easy solution. Put both side with two Goldwing Vans and radiators under the air scoops.
Problem solved
I has a Chinese made reverse recumbent motorcycle the cool thing about it was the suspension it would lean into a turn it looks like different suspension for turning might make it safer and better handling in a turn cornering just a thought from a novice would not want to hurt the look of a plane but even plane wings have wheels.
You can cut and bend a piece of sheet metal from the bottom to collect cool air and blow into a radiator.
My dad owned the 24th Pulse autocycle ever made. In fact, when my dad bought it, it wasn't called a "Pulse" yet. It was called the "Invader 2000", but the creator had legal issues with that name because Honda owned it, so it became "Pulse". His was white also, but after a funny incident where a Japanese tourist looked in his rear view mirror and thought a jet landed behind him, and slammed on his brakes (because of course you should slam the brakes if a plane lands behind you (sarcasm)) causing the nosecone to need replacement, my dad had it painted burgundy. I was curious to locate it and see if I could buy my dad's Pulse and fix it up for myself. I found it on a Pulse registry. It's still the same color with the same custom leather interior my dad had installed, but the frame, engine, and body are too far gone to be salvaged without just rebuilding the whole thing from scratch unfortunately.
*Edit* While watching the video, I'm having flashbacks of the overheating issues it had. We had to modify the air vents on the sides over the engine to have scoops rather than vents, and we also installed vents on the body on top of the engine as well. It helped, but it would still get hot. They originally had a Yamaha 400cc engine. That fuel switch on the exterior was added by someone, and wasn't OEM. Ours also didn't have a clutch issue like that one, but ours also didn't have a reverse, and you had to be mindful of where you were parking it, or else you were going to be pushing it backwards. I drove this in high school, and I called it my "p***y mobile" because all of the girls wanted to date me. We got pulled over by cops just because they wanted to check it out. People took pics of us from their cars, and our Pulse was in the local newspaper (for the funny accident story) as well as The Dallas Morning News as we had the first Pulse in the DFW area. It turned a lot of heads.
I’ve seen two of these over the years. One in Texas, the Dallas area and one in Arkansas around Hot Springs. Always a head turner!
Indy cars have top scoops for air flow. Reason: heat rises, so before fan , heat of engine rises into cowl shedding cooler air down and under. With fan you installed and heat rising taking path of easiest resistance on an cowl reverse facing will force cooler air in intakes and under vehicle and force out of the cowl that Indycars have or something sleeker over gastank..
This might sound crazy, but relocating the radiator into one of the side-wings might be the way to do it. (Look at how some WWIII aircraft did wing-mounted radiators.) And then the main body can be cleaned up again for aero.
As a person who has never ridden a motorcycle but rides a Logitech GRZ-1000XR keyboard for 17 hours a day on the internet in my mom's basement for the last 30 yrs I have tons of unsolicited advice to offer. The first 700 bullet points are the main ones...........................
Cool video man- BS aside, there used to be a yellow bike like this here in Austin on MoPac advertising an insurance business, so have always wondered what they were like. Thanks!
These things are so cool! Loved this video. There’s a guy around the corner from me that has something similar but gold. Never seen him drive it yet. It looks awesome
Think about this. The fans on your car are behind the radiator pulling cool air through it. Never in front blowing on the radiator.
