We bought an old mini bike frame and two 8 HP Briggs and Stratton engines, and we're off to Go Power Sports headquarters to modify our chassis, get our engines running, and assemble our twin engine mini bike in time for our subscriber meet up the next day.

Most 'Franken' thing about it is the gearing ratio of the chains... looks like about 6 or 7:1 for a '4 HP engine'... but only needs about 1.5 - 2:1 for 8 + 8 = 16 HP torque !!! ... Would feel like super strong '1st gear only' acceleration... then no shift into 2nd available... The engine braking from letting off the gas would prolly slide the rear wheel... This thing also needs #40 chain instead of lightweight #35 'karting' chain...

@ExperimentalFun 6 жыл бұрын

You should put a clutch on the front engine, put the sprocket side in so it can align with the rear engine sprocket, I think it will work better and also you will only have to start the front engine.

I was thinking figure out the compression stroke on each and set them to 180deg off of each other so it runs like a real 2 cyl! Maybe also a 2 into 1 exhaust? Two smaller headers feeding a double sized? (more cosmetic than performance).

@olds97lss 6 жыл бұрын

Use a much larger sprocket tying the two engines together with a spring tensioned idler to keep the tension so the chain isn't flopping all over, perhaps a heavier chain, then put a torque converter on it! Regardless, I love how you guys stay the same regardless how much money is around for things. Still making stuff any Joe could do with a welder and some parts. Love it! Look forward to your new videos every week!

@sirbow2 6 жыл бұрын

I think it'd help If both engines were syncronized in relation to the power stroke of the piston. I m guessing that right now that one engine hits the power stroke after the other and it creates a massive torque differential through that chain when the other engine is in the compression stroke for ex.

@Acoustic_Theory 6 жыл бұрын

Yes, phasing between the two engines will break that chain in time. But for now "it'll be fine".

I saw that chain between the motors dancing and I thought, even with synchronized motors, one is gonna fire first and it's all fun and games until someone loses a femoral artery. I dunno about this as a solution get the motors timed as close as you can and short the spark plugs together or trigger the magneto primaries together off one motor.

Use a belt to connect the two, that way theres a slight amount of slip if the motors dont agree with each other. Make it kind of like a tiller with a tensioner pulley and when they're both idling you can flip the tensioner pulley to connect their power together

Looks like you guys all had a blast and good job on the quick build. I was wondering if maybe the engine power pulses were working against each other causing that sync chain to go bananas. Seems that it would be hard to ever smooth that out very much even with additional idler sprockets, but I could be wrong. Maybe stagger the engines left to right and use two rear sprockets, two chains, and the two clutches. That way each engine could be independently connected to the rear axle and they could be started separately and use the clutches to smooth the power between the two. I'm just thinking is all my friends. Again great job and I look forward to what you come up with next.

Dad was always particular about how stuff was done, and later on after dealing with projects that had been jury rigged I came to appreciate his way of doing things. Yes, it takes time, but if it prevents a problem down the road it's usually time well spent.

I got there, the engine was put together, and running. His wife was cutting grass. He looked at me proudly and said, see? I didn't need a hotshot mower mechanic, I did it myself....just then, there was a loud CLANK from the mower and it stopped. The rod broke from the rod bolts coming loose. I asked him, where's the rod bolts retainer? (It's a thin piece of steel that goes over the rod bolts that you been the tab on it over the bolt to lock it in place) he dug on his bench and held it up and said, this? I didn't think it was important..🤔🙄

That probably cost em 30 mins right there, not to mention the bickering over stupid shit and all the other little nitpicking wastes of time. Ike gets shit done. Plain and simple. That RBW dweeb is antisocial and opinionated with super thin skin. I'm proud of Ike for not laying him out, can't say I'd have the same restraint. And for the record, that gear broke cause someone cut a keyway in an already thin gear, you know, instead of welding some strength into it. 🤔 food for thought.
