The 550cc Little Tikes Cozy Coupe go kart gets some time on the dyno! We're not sure if our 1970s Honda CB550 engine is the 38 horsepower version or the 50 horsepower version, so we're going to find out on the dyno! We got the Cozy Coupe go kart set up and strapped down on the dyno, and we quickly realized that we were having some kind of ignition problem- on our first high RPM dyno pull, we could literally hear the engine running on four cylinders, then two, then four, then two. We pulled the spark plugs to find that one of them was shorting out.
We made a quick run to the parts store and were ready to resume testing! Unfortunately, we're still having some sort of ignition problem, because our two-four-two-four issue persisted. In the future, we'll order a new set of coils, tune the carburetors, and give it another shot!
Thanks for Watching!

@@barryallen6293 did you also notice they didn't put TH-cam ads in the video then? They got their revenue for the video by giving you one ad you can skip by hitting the fast forward button a few times and it's like it never was there, as apposed to 2 or 3 midroll TH-cam ads that you can't skip for 5-15 seconds. They made this video it the way a person with your kind of mind set would like, you just don't even realize it.
Guys if your carbs are not balanced the jets will cause cylinders to drop out at high and low rpms.
I love ur channel but still...raid shadow legends? U stooped a lil low here
The more money they make the better content they can produce. Give them a break
ohhhh that kart is glorious
i’m building a trike with a 160 honda
any tips?
Ike: "What about me!?" John: "you have a twin brother..." ouch. lol
I was laughing so hard at that 😂
I died a lil’ on that.. he has a spare/clone/replacement/exact same model n’ make 😂😂
@@teenlaqueephaData and Lore from star trek one works with evil bicycles "Lore"... etc
Best reply ever!
When I was a younger man, I always wanted to stick a motorcycle engine on a go-kart frame because I knew that it would be faster than a scalded cat. Now that I'm old and retired, I can't do that project myself but I'm happy to see that there are several TH-cam channels doing this sort of thing so I can at least have a little vicarious enjoyment of those crazy things. Thanks, guys! 👍😊
I loved the part with Isaac eating pizza super slow while everyone else was working on the cart when the camera was going super fast
same here
That took a lot of restraint.
@@charged I bet there was a bit of drool :P
So I was there and Ike was drooling a lot
You guys need to make an "It'll Be Fine" shirt with a cartoon Ike on the Tot Rod with that respirator mask!! That'd be AWESOME!
Kartssource with a Big Daddy Roth style Ike on there with the mask. I’d totally buy something like that
Ref. Ed Roth's "Mother's Worry" 😂
Kartsscource I second this motion!!
As well as Greg Castro's!!
Dyna coils, dyna ignition and run the center 2 carbs slightly richer than the outer 2 for max performance. Ive been running 70s hondas for 20 years, great engines!
whats the deal with running the inside richer? Is it a flow thing? or heat? im totally curios
@@gibbyrockerhunter the center two cylinders run hotter than the outers, a little richer keeps em cool
@@Chris_Bumpus makes sense and is good to know. thanks dude!
MyLiveandletlive do they though.
@@Chris_Bumpus yep👍same thing for the kawi triples🍻
John: 'I don't want the fan to tear this thing up.'
Isaac: 'WHAT ABOUT ME!'
John: 'You have a twin brother.'
john morgan 😂
The C10 looking mighty fine!
4:55 YOU GOT A SPARK PLUG WIRE ARCING!!!!!!!!!!
Ive been saying this every episode!!!
good catch
@@nelsondavis4310 I hope they read the comments
3:24 - No they don't have an arcing plug wire.
Look at 3.24
7:50 you can see spark jumping to the head... change the wires
the answer lies at 3:24
Dang!!! I went back and looked at it. Dude, you are completely right!!!!
That kid standing by the post, probably waiting for it to explode LOL!!!!! Great video.
2:00 skips the ads
Mobile game ad...they joined the dark side lol
@@lobmin I thumbs down every video with these terrible ads. 2 minutes worth. I'll just watch tv instead.
@@Shredxcam22 eh, I really can't blame them...with the amount of free videos and the ability to just skip past the promotion, I can live with it.
@@lobmin the reason I watch so much youtube is to get away from being bombarded with commercials. Less youtube= more time in the shop working.
@@Shredxcam22 If you thumbs down a great free video because of an ad you choose not to skip, you're a filthy piece of work. Stay off the internetz.
Make a small burn out car for Cleetus and cars 😈🤙🏽
Welcome to TH-cam, sponsored by Raid Shadow Legends...
Sync the carbs too!
They do need to sync the carbs, impossible to do with their carb setup tho. They need to get an original rack of carbs on it.
Isaac eating pizza in the timelapse = golden. cracked me up so much. you should do more of that stuff. xD
Lesson number 1, run it up and down the road to make sure the tune up feels and sounds good before heading to the dyno. Lesson number 2, always take spare tune up parts and good fuel to dyno session. That little kart looks like fun, glad you guys are having fun.
Hey John, let’s have an update on your pickup soon. It’s lookin good!
The RPM signal bouncing is also giving you incorrect numbers too. Because it uses RPM in the equation to calculate torque.
RPM isn't used to calculate torque, it's used to calculate hp
@@rbgamer1008 Correct. But it's hard to explain. On an inertia dyno, since the mass of the rollers is known they can calculate horsepower without an rpm signal into the machine simply by watching the rate at which the drum(s) accelerates. In order to calculate torque it needs the rpm signal because it doesn't know if your engine is say a diesel spinning at 2,000 rpm or a motorcycle at 10,000.
Leaving the key on all night might cook one of those coils. Been there done that on a '74 CB-550. Need to test those coils. (Edit: Should have waited to the end!)
Guys, I can see a small spark on the second cylinder. It's the plug wire shorting to the frame. Check the plug and wire.
What about me??
You have a twin brother...
😅😂🤣 Isaac is irreplaceable!
Apparently interchangeable.
Ike: I want to be pleasantly surprised and not let down
😂😂😂
👍🏼before even watching this... : )
LOL@ you have a twin brother! 🤣
hmmm my notifications say you hearted my comment, but its is not seen?
TY for correcting this... youtube censors me a lot...
Fit a Dyna electronic ignition and coils, then tune the carbs I’m sure you’ll see around 45 to 48 Bhp
Good luck you pair of nutters 👍😂🤘
You guys should check the coils but also check the plug wires. I used to have a 1971 CB550, it was doing something similar, it would randomly cut out on 1 and 3. I pulled the plug wires and found that there was a broken wire inside the insulation and it was barely making contact giving me the intermittent misfire. In your case I would put new coils and wires
Coils and electronic ignition ditch the points
A condenser is likely the culprit.
Points worked for like 80 years, just don't neglect your equipment
for it to get fried even harder by leaving the ignition on?
@@lobmin yep nothing wrong with points..when in good working order they perform well and very reliable.
I love this channel man, y'all should bore the jugs 30-40 over, port & polish the heads, put titanium valves ,wiesco timing chain, mill the head, then put stage 2 cams in it , jet the carbs , and with all that being said it would be stupid fast, but... You prolly have to run av gas however could you imagine the POWER!!!!
Raid finally made it to this corner of YT huh? About dang time you guys get some love.
Your break up may be that you are arcing at the top of the engine at 8:00
Still? I saw that on the first video and many people have mentioned it. Why aren't they looking into that? Hmmm
I see that🤔🤔
thats a rpm counter for sure :D
You can hear it on the audio with headphones on clicking..
the answer lies at 3:24
Guy,
That truck is looking great!
Condenser over heated and burnt the winding- Points were not fused together. Also magnetic pickup probably has weak pulse caused by feedback from condenser. Just a thought
If you are worried about ignition burning Up coil’s, maybe put a Killswitch under the seat so that the ignition only is on when there is somebody sitting in it. Neat trick that a lot of riding lawnmowers use.
You can put a pressure sensor in the seat that you made that way you won't accidentally leave it on it'll cut power to the ignition switch like a lawn mower switch that way it can handle the amperage and also if you fall off it'll shut the engine off more safety
I LIKE the tech talk side. I've learned a lot. Thanks John and Ike!
Awesome Little Tikes car. Kids have it so good today.
Tim Allen is somewhere right now making his weird grunting noises to this go cart! 😂😂
Truck is looking pretty dang good from what I could see of it..can't wait to see it when it's done.. looks like you're doing a damn good job with it so far.
It was fun watching video👍. "FIT IT!" "GET'TER'DONE!!!" RIP A GOOD ONE!" "SCREAM'IN FART!!!"
If you watched your videos, you can see a spark plug wire arcing to the head on the left side. It has been, since you first started it.
Its the Tach drive. Look at 3:24.
As always, your vids are funny as hell!...It seems like Ike always has to do the dangerous tasks while the smaller, bearded dude cowers in the background until the coast is clear!...Again, you two dudes are hilarious!!
Dude the truck is coming along that silver looks great
I'm putting one of those motors in a go kart right now. Can't wait to get it done!!
I had a 1975 Honda CB550 Four, which I'm guessing is that exact engine. I had a lot of fun on that in the 1980s, but at some point it stopped wanting to run. It would foul the plugs in nothing flat. I tried everything and finally gave up. All I had was basic hand tools, though, nothing like the shop you guys have.
As an "old school" guy... I'll tell ya, ya gotta get the carbs balanced and it'll really run butter!
Can't wait to see you guys get the rat rod Kart dialed in. It certainly seems like she's got more potential than she's showing on the dyno at the moment And those torque numbers are already crazy for what it is. Also, I think it would be absolutely amazing if y'all could tie in with Cleetus McFarland and crew and maybe hold an event at the Freedom Factory Once it's officially open. But beyond that, keep Doing what you're doing and looking forward to seeing the end result 😃
I still think you could use the yellow roof as a hood over the engine
The tot rod sounds great love the pipes lol nice build
The twin brother thing made me really laugh lmao
You guys need a shop with all your cars. dope car lift btw
well done gents
it's 2am in mornington peninsula and still watching
John, you seriously need that truck to be pin striped by a pro !
Isaac..When u pulled the plug and it had like a little hair or something bridging between the tip to the base...that's the cylinder running very lean...It is actually pulling tiny bits of melting aluminum from the piston and collecting on the plug.
73 people don’t have a clue!Way to go guys!
We need spark plugs! Has a pizza on top of the engine 😂
Get after market cdi electronic ignition and install it make sure valve clearances are correct and balance carbs then dyno her, that's when you will get true numbers and be pleasantly surprised. Thanks for sharing guys.
Thanks for having your sponsor on at the start of your video as it gave me a chance to go and have a pee pee 👍
Why not invest in a wide band o2 sensor kit to set your carbs? For $150 or so you weld a bung on each exhaust runner and get an accurate reading of the afr, and go from there. Then when you're done, screw some plugs into the bungs and you're good to go. It'll be helpful for troubleshooting as well.
Regardless of what power it made. Its badass. Yall found some gremlins. That's always a good.
Look forward to the next video.
guys look at minute 4:48 at the left cylinder head, there's an arc maybe that's where the power is going? Love your videos, hopefully, little tikes run like butter again soon :)
use a multi-meter and ohm out your primary and secondary on your coils from this set, and keep the best from both sets for "just in case" spares also might upgrade your coil wires to larger diameter like 8.5 or 8.8mm to get more fire to the plugs, she sounded pretty sweet after you changed the plugs and did a little work but as ike said, shes not quite "singin'" the way she was before at higher RPM so either you've got weak insulation or a cooked coil, either way y'all are loosing fire from somewhere, still i love this build, its like the rat-rod wagon on steroids, and i cant wait to see the final HP/TQ numbers when shes running on all 4 cylinders, one step at a time guys like you've been doing, you're slowly running the grimlins out of the project, one small issue at a time
Thanks, guys and nice twin brother burn John.
You should talk more about the red Nissan behind you. That thing is a classic 90s Japanese sports car
On the Cozy Coupe you guys should get a wheelbarrow and cut the barrel in half and make it like a T Bucket that would be sweet
Can't wait to see the video of the truck
I love your builds but I find it ironic how the mower was too dangerous but this is fine LOL. Keep up the good work
mower was way too top-heavy compared to the wheels' location.. this little machine has a much better CG.. set the weight low, not as easy to flip over
That shot of Isaac on the rollers with that gas mask looks so tough! Love it! Lmao 😂
Electronic ignition, wires, and balance the carbs (check the diaphragms first)
There was an arcing plug
Well the build is done ... now comes the tuning .. it actually sounds pretty good .. but by the look of that plug “ you should be ashamed of yourself “ lol ... going to the dyno and you didn’t check the basics ! Omg smh ! With a plug like that I’d say the carbs are rich .. that will kill power quick .. especially on gas .. and will also make it run hot .. people think rich always runs cool .. to rich and it gets hot .. lean it out for some more power .. don’t think you’ll find as much as you think tho maybe 5 more HP tho .. really cool projects tho .. thanks for posting the videos .. love them all !
Your spark plug wires are arcing like crazy! I think your losing alot of power from that!
My guess was 42. Either way she's a ripper! Badass
Did anyone else notice the spark arc at top of engine while it was running?
I always enjoy watching your videos
Had the same problem with a 1979 Suzuki gsx 1000 . I put new plugs, new points an condenser, the the 4 carburetors rebuilt and tuned to find out I had a shorted out coil at low rpms. I fixed the two coils and now the bike is so quick on take off it's scary . You should check out bike barn for parts on the older bike parts.
those tires bounce SO much. y'all need to get that fixed lmfao
Truck paint looking mint
Since you are replacing stuff it wouldn't hurt to have new plug wires and check signal throughout the entire electrical system. There might be an intermittent contact that was created by being over heated .
I have a 1985 yamaha dt50mx , when the condenser goes bad the whole bike loses power and then after a while leads to a missfire then backfires and wont run. Definitely makes a difference
I see Raid has made it here too. When are they going to sponsor my dashcam vids?
Your c10 behind you looks great.
Hey you could see stray spark on the cylinder head! Check the video at 8:01 you can clearly see the spark jumping across.
4:45 Spark jumping from wire to valve cover! Everyone comment this so they see it!
3:24
that's the broken tach drive
They make a CDI ignition for those bikes I used to run them on my old 750. I think Dyna, axcel has kits for those, it's been many moons. Good luck guys I enjoy the videos can't wait for the updates
It's probably just the carbs. A clean and tune should fix it. Awesome build guys
It's definitely not the carbs .
Anyone else notice Luke’s landspeeder in the back? 12:36
It's called bridging when that gunk shorts out the plug = you have some oil consumption issues ... I guessed 32 hp :)
Add a battery cut off switch? Having had similar probs with a 750 G, being absolutely sure there is no stray voltage finding away to the points, coils would seem worthwhile. Ike- I cannot wish you anymore fun than syncing four carbs, especially if you don't get the ignition problem solved!
😂 You have a twin brother, your killing man lmao 🤣
If you gave the engine a good refresh and quality ignition, carb sync and jets it'll make 53 with the pods. They make 50 stock. Well that is what was claimed back in the 70s. But then again that was probably at the crank. So I'll say 44 horsepower if properly set up.
That thing would be stupid sick with a busa twin turbo set up on it.
I love the cozy coop build so far
make sure the new coils are bolted down and not hanging of some metal wire , that can cause bad ground too
You guy are my favorite youtubers keep up the good work
John, the old pickup is looking good.
I’ve had an idea for y’all. I wanted to do something similar when I was a kid, and it hit me again at work while putting a transmission back into a motor grader...
what about a 6x4 off road cart? The rear axles, if live all the time won’t allow you to steer, but a dog-style clutch or electric pto clutch from a mower could be used to engage the drive to the center axle.
I have wanted to try something similar to the grader, too, where there is only one “live” axle powering two stub axles in a walking beam on each side, but it would need a differential to allow it to turn.
It's a 55 horsepower motor (crank) which is mid 40s at tyre .
Your coils are damaged due to ignition being left on .
I have owned & dyno'd loads of single cam 550/4 Honda motors
A can of starter fluid at the Dyno next time. Spray it in at top RPM to see if the breaking up, smooths out. If no, then yea ignition or some other limiting factor.
You guys should run a compression test and set the lifter clearance. It sounds kinda iffy boys.
You might already know this but most motorcycle transmissions dont actually have an over drive so 5/6th gear aka the final gear is usually just under or at 1:1 and for most dyno power pulls you want to be at 1:1 or as close as can be which is why in a manual car on a dyno they'll run in 4th because 5th adn 6th are over drive gears. You dont want to be in underdrive because it'll give false readings most likely more torque and less hp from my understanding. So if you plan to go back to the dyno please find out which gear is 1:1 it'll give a better more accurate reading then it being in third or forth unless for some reason this bike has an over drive gear and is more like 0.7;1 or 0.9:1
you can use gm coils from a 2000 firebird v6 in place of the stock coils. can also use them on an ez-go gas golf cart. i use the hp gm coils with 8.8mm wires.
