670cc 2 Stroke Go Kart FULL SEND | "Neighbors' Nightmare"

Our Ski Doo Mach 1 powered go kart is the most powerful go kart we've ever built. Weighing in at under 400 pounds without a rider, this 125hp go kart has a better power to weight ratio than a Dodge Challenger Hellcat. In today's episode, we install a muffler, fix the floor, install a chain guard, and send the snowmobile powered go kart around the CarsandCameras circle track, and do a burnout until the rear tires pop!

Every 3dB, the sound energy doubles(twice as loud). The mic in your phone isn't designed for anything over 120db and the exhaust is more like 145-150 at the pipe.

[@garrettstevens2232]

I kept thinking they should have measured from 100-200 feet away so they wouldn't max out the phone's microphone.

[@thezoomguys385]

They shouldn't be measuring indoors like that, as the reflected noise will really throw off the results. Also need to test at the distance & angle each time. We test bikes using SAE J1287.

"126db.... Not great but not terrible...." Don't think the phone mic is going to pick up much more than 120dB. Still that thing is nuts. Good stuff as always.

[@ivyisle]

It's 15000

[@SilvaDreams]

Plus the mic was facing away from the source so it wasn't getting a good read anyways and it was inside so it was going to read louder due to the reverb.

[@ian3166]

Continuing to remind you guys about the necessity of warming these snowmobile engines up. They need to sit for a bit or they are going to blow something. They make lots of power, but give her a few minutes before you send it! Looks terrifying fun! If you already do and cut it out of the video ignore this.

[@MrJdsenior]

It's a contest between "what they oughta" and "what they wanna". And with a bunch of adult sized kids, which do you think will most often win out? Just sayin. 🙂 This because I know several, and to be honest, sometimes am one.

[@ian3166]

@@MrJdsenior yeah, I own one of the sleds these engines come in and I'd be lying if I said I've treated it perfectly all the time. Just trying to warn them before they have a early end to this hilarious build.

[@LeObsidianCraft]

@@ian3166 you also gotta take into account that at a minimum this motor will be at 40-50F ambient. No wear near as cold as a normal sled will see at most 32-anything below F (maybe 40/50 for the last ride of the season) So the motor is already at least 10 degrees ahead and in NC it will probably see more like 40 degrees at a hot 70 day

[@HellmuthsHotRods]

"Cold seize" is a term in the snowmobile world.

[@tstuff1213]

@Dobbies Revenge They live in North Carolina not sure thats considered the south. Also like ike mentioned the muffler they put on it was soaked with oil so when it got hot it was burning it off. Also not at all surprised if its smoking more than normal its an old 2 stroke that has possibly never been gone through.

[@crottemole]

Its hard to imagine just how incredibly loud a snowmobile engine actually is unless you heard one in person... the way the sounds just echoes back is like nothing else!

[@gavinw4165]

Braaaaaap

[@crottemole]

Yea. Mabe the oil injection pump is stuck fully open. Had that happen to me before.

[@thedude7726]

Its smoking because its being ran in not winter conditions

[@gavinw4165]

@@thedude7726 no it’s not, it’s because the spark plugs are fouled because too much oil is on them and that is why it is hard to start and needs to be opened up before it starts running properly

[@crottemole]

Jetting might be off. Plugs wont make it smoke more tho. Either the oil injection pump is set way too rich or stuck. Or they run premix in adition to the pump. Mabe the open primer ports affect a/f r too. Im no expert.

[@SabastianU]

Charles' pure, unadulterated joy at driving this thing was awesome to watch.

[@sandmanbub]

4 diodes and a load resistor should be enough to convert your ac to dc with minimal voltage drop. You could also use a lightweight voltage regulator from a racing dirt bike.

[@bobadam7021]

I love this thing and I hope it means a lot more 2 stroke content.

[@supertedogpriken]

yea can never have to much 2 stroke content. And going by there latest builds it kinda seems like they are out of ideas of what to do with the predator/brigs and straton type of engine.

[@jbuch66koop]

A little easier explanation of decibels is, for every 3 decibels, the level of sound doubles. So 123 decibels sounds 2x as loud as 120 decibels.

Crazy story… went to Down Main Street ( restaurant in Washington, NC) this past Saturday night, and got seated and ordered and then walked out to get fresh air with my friend and then came back in and this man (Issac) was sitting at our table and, with a slight bit of confusion, we sat down and decided, screw it, you can eat with us, brother. Never met this man in my life and had no clue who he was. Turns out he was a really good guy and told us about this channel he was involved in. AMAZING CHANNEL. I love cars/trucks/bikes/hp/speed. Good meeting you, Issac. Small world 🌎.

[@charlesgrave]

The good ol sound of the Rotax 617cc. My father still has a 92 Mach 1 in very nice condition. The key to starting it is to prime it a few times and when starting it have your hand holding the throttle and blip it from there

I've had to do all my welding mods on my truck with flux core wire with a 110 Lincoln and have had no issues with welds breaking. Yes gas would be nice, but my pockets run shallow and I can't afford to buy and keep filling a 300cf size bottle.

8:05 There is absolutely nothing wrong with a Gasless Flux Core wirefeed weld. A big gasless bead being weaker than a small tack with a MIG? GIVE ME A BREAK. I'm not sure where this bozo got his welding certificate. The downsides to flux core? Harder to weld really thin, more sparks, more spatter, and more smoke. Benefits to flux core? Deeper penetration at the same amperage! MUCH better for welding ourdoors in breezy conditions.

A bike that can do 108mph in 1st gear is something else.

[@sammcbride2464]

Mainly, it is due to the journey to the destination and the destination ride. I don't need a truck are anything else. Just a backpack and a wallet.

Welding with a big mig is definitely much easier for go karts mini bikes etc but those 90 amps are a good bang for your buck and will work good starting out for anyone thinking about it.
