We Installed 3 15+ Horsepower Engines and a 3 into 1 Exhaust on our Triple Engine Mini Bike

Our 3 engine mini bike gets 3 high performance Honda clone engines! We removed the three Tillotson 212 engines and replaced them with a built 196cc engine, a Tillotson 225cc high performance engine, and a built Tillotson 212. This is one fast mini bike! This mini bike is so powerful that it does burnouts... at 40mph. We also built a three into one header for this drag mini bike to test the performance and sound!

I think I figured out why you won't respond to the V-Twin 27 or 25 horse or 30 horse Kohler Engine off of zero turn lawn mower from a Toro or a Exmark something like that but it has to be a V-Twin and it will work on a go-kart or a mini bike it would work awesome, so I'm taking it you guys just don't know how to do it

[@ajamlin5834]

Idk if you guys can do it but what if you installed a push start for all 3 engines so there all in sink or am I just saying nonsense lol

[@Rev-maniac7500]

@@ajamlin5834 based on how each engine had different responses in the video I don't think they would start all at the exact time and the problem would be if 2 started and one Didn't start you can't start the 3rd one because the others would already be running and it would overrev the starter motor

[@FreakinMosin]

You need to direct drive each engine together and then stagger the firing order. Put the clutch on the last engine. You'll have to rig up some sort of starter to get the 3 engines running this way though

nah you just gotta have the arm strength to pull all 3 engines with one of the cords lol

[@crudboy12]

@@Sausketo Should be doable. Snowmobile engines frequently have a pull cord and can be 1000+ cc. They are only dealing with ~600cc so it shouldn't be any worse than the rotax go kart with the 670.

[@edwerts7096]

I think it would be really cool and the perfect build to make an inline 3 to 4 cylinder engine out of 5hp briggs flat head engines. Ive seen people take a couple flat head briggs engine and build them into one engine connecting the cranks together. There's alot of vids on here about doing so. I just think this would be the perfect bike to do it with. Make like a 4 cylinder inline rat rod bike.

[@matthewcalifana488]

True ... but this all goes out the window if mixing bore or stroke.

[@brandonfloyd6321]

Theres a guy here on KZbin that was building a radial engine from briggs flatheads years ago.. Roadking something was his KZbin name.

[@willscott85]

Yea roadking also built a 4 cylinder Briggs before the radial, and a water cooled briggs

[@esqueue]

@@brandonfloyd6321 I checked back about a year ago and the radial was still never completed.

[@liamwatts8597]

Could be cool in a new radio flyer?🤔

[@desertdenizen6428]

I think 3 equal length pipes into a collector should solve most of the exhaust system problem. Unless you can somehow get the engines firing order 120 degrees apart, they will confuse the exhaust effects. IMHO. A really fun build!

[@patrickmchose7472]

Nah - motors are completely out of synch. Pulses are not timed.

[@desertdenizen6428]

@@patrickmchose7472 If the engines are locked together with chains and the sprockets and are the same tooth counts, the RPMs should be identical. I need to correct my previous comment, the engines would need to fire 240 degrees apart to time the exhaust pulses equally entering the collector. I am used to tuning 2 stroke engines. :( Only the last engine should have a centrifugal clutch and be beefy enough to withstand the power of three engines.

[@bbevis2357]

Since you started the other 2 engines first it blew all the welding debris into the 3rd which probably happened to have the exhaust valve open. The 3 into 1 header is cool but 3 individual exhausts is much more practical for this setup. 3 'zoomie' headers would look sick

[@spyder7758]

Shared exhaust without having the cylinders in time sounds nuts lol can't wait to hear it and see what it does, 3 firing at once will give you a lot of pressure

[@arronk09]

Another problem you might have with the exhaust situation is that the scavenging effect is dependent on valve timing among other things. Since you dont have all three cranks synchronised, the valve timing from cylinder to cylinder also isn't synchronised so the exhaust pulses aren't timed to help with scavenging other cylinders. If you can "time" your cranks 120 degrees apart from each other, that'll go some way to helping. I look forward to seeing what you do with it!

[@cr500_conversions]

Not with these. Not enough to be detrimental I would think. The length of primaries are too long to interfere with eachother.

[@Herbybandit]

You can't time them unless they are continuously locked together through the chains as if they had a single crankshaft. You see as soon as you start the first engine the timing is gone! The first engine is spinning while the others are stationary.

[@ZrubekFamily]

On a V8 you have 4 primaries going into one collector. They have one primary going into another primary going into another primary. That's what the problem is.

[@kasuraga]

@@Herbybandit Yeah, they'd have to run fixed sprockets to link them together instead of clutches

[@matthewcalifana488]

@@ZrubekFamily Yes , not equal length / the inside of the collector should be triangle shape @ 120 degrees .

[@callmecardo916]

Watching your videos always puts a smile on my face, Funny how everyone was looking at each other when the engine was locked up. 👍🏼👍🏼

[@jeremiahdane3021]

I can understand the difficulty of mating engines together, I know an older gentleman that has two SBC's on a pulling tractor that were timing syncro'ed and had identical parts inside and out. He tried a common header between the two and had instant torque down low but lost everything beyond mid-throttle. The exhaust pulse was washing out the other engine. Went zoomie headers and tuned each engine till it was happy and had much better luck. The healthiest engine will suffer HP&TQ loss but it will "boost" the lacking engine (in a perfect world). Good luck guys, still a cool build to learn about. Keep keeping!

[@willedmunds3818]

I think the whole 3 into 1 header idea is good in theory. If all three engines were linked together at the crank via a heavy duty chain you could optimize the firing order for maximum power through the header. You’d also be able to run the whole setup through one clutch/torque converter and it would sound significantly closer to an I3 rather than 3 different engines running through one exhaust. It would be harder to start but two of you guys cranking at once could get it running. I’d love to see something like that on the channel!

[@CMPLT_PLYZ]

It would be a lot of work, but I would be curious to see the 3 clutch setup run to a jack shaft that is running a torque converter to the rear wheel. You could get the gearing you need to run it out on drag strip and give your drive line a little cushion for the random firing order on your engines. Cool build guys.

[@CarsandCameras]

We talked about doing this, and yeah- lots of work. We're going to try messing with the gearing and weights on the clutches before we try swapping to torque converters.

[@benprihoda5903]

Y’all need to tie all three engines together with solid sprockets and chains then tie them into a jack shaft with a heavy duty clutch on it so it can still spin freely of the tire. This way you can also clock the engines together to have a real firing order. Really wouldn’t take much to do.

[@jlucasound]

Yes!! AND Equal length pipes from each engine to a shared collector. Like a true header.

[@gonewronggarage4565]

If you start 1 engine that all of them would actually start if you had it like that.

[@123Poppa321]

I was just about to write the same. I think a real firing order will make a difference as well as same length headers.

[@MaNNeRz91]

Would just keep snapping chains when one engine is at a higher torque than the others. All 3 engines would need to be perfectly tuned in harmony and you couldn't stall one (which would happen) because it would destroy it

[@garrettstevens2232]

@@MaNNeRz91 with them solidly connected they will rev together. A small torque difference won't matter, the weaker engine will just be helped by the stronger. You would only run into problems if one of the engines backfired.
