V Twin Go Kart Custom Header, Intake Mods, "Black Widow" Paint

[@Maverick_Van_Traveller]

Am I the only one who thinks the green wheels should be red? Especially if you are gonna call it the "Black Widow".

[@CarsandCameras]

+M Kefer I agree, but the audience voted for black and green! We might change it anyway.

[@NOOOOOOO0OOOOO]

+CarsandCameras Yes black and red and give it some white walls.

[@eoinurquhart2306]

Yeah that'd be good

[@andrescalderon540]

I agree with this dude let's do u it

[@thathondachannel2105]

+M Kefer black widow.... YES

[@bobcatstillwell4844]

You guys do a great job! Interesting, educational, and totally entertaining. I'm 52 years old and this stuff takes me back to my chikdhood. I grew up around mini bikes, go karts, and motorcycles. I am half tempted to buy a go kart. They were so much fun as a kid.

[@tomzborovsky6315]

put fog lights on it since you guys are always driving it around at night. plus, it'd look awesome !!

[@thenerdycanadian7172]

+Tom Zborovsky red fog lights

[@calumanderson571]

+TheNerdyCanadian would not be efficient at all for the light it would produce

[@thenerdycanadian7172]

[@tomzborovsky6315]

+TheNerdyCanadian I'd say it would need to be useful. :P that's the point of lights

[@ethanbuhlman7156]

Yeah put a fog light on it that would be sick good idea

[@tommeaden8219]

I am completely obsessed with what you have done and thank you for inspiring me go make my own home made go-kart from a lawnmower, school table, mobility scooter....

[@gbub]

What happened to changing the sprocket? Higher speed testing? Competing against the Corvette? Bit of a stretch to say this was completed!

[@CarsandCameras]

+GBU Sprockets didn't arrive soon enough to be in this video. It'll be in a future video with this kart. It may be "completed" as in running reliably, but it is far from done. And the Corvette race was never set in stone, but we would get destroyed the way the kart sits at the moment.

[@jawnske]

+GBU if u ever built a mini bike or go kart or some kind of project car you know theyre never "completed"

[@trickpierce8196]

+CarsandCameras it is a nostalgia top fuel dragster

[@aaronl4036]

Thanks guys, you were partly responsible for my decision to dig my vintage mini bike out of my parents shed. It is now rebuilt with a modded Predator 212 and torque convert. :)

love it, ive actualy been planning on doing a vtwin build for about 6months now, but you need to prioritize guys. You started the $50 gokart, started the ratrod , then started the vtwin, then finished the $50 then the vtwin, and have thrown the ratrod on the backburner

+BF4_Legion am I the only fucking one who thinks they mean the same thing on a 4 wheel vehicle?

[@rmaul2469]

+James Andux lol i used to but they don't. 4wd is all wheels all the time awd is lsd where all wheels aren't powered all the time

[@BigMuddyCountry]

+BF4_Legion actually it is just opposite, 4wd means you can switch from 2wd to 4wd awd means all 4 wheels turn at all times, hence being all wheel drive.

[@ogxbmc]

+Waylon Richardson wrong.

[@FASTWARSHIP2012]

A 5-speed peerless transmission would be a great addition to one of these, I saw one kid do a cool 'shifter' kart on here although the engine would have to sit differently... and I've seen that people have been using smog pumps off of cars as superchargers, it would be awesome to build one of these for the dry lakes as a small cubic inch land speed machine with a supercharged 5-speed V twin. From what I've seen, I think it might also sound a little more harley-esque if you tie the header pipes together and step up in diameter like this one kid did in his minibike video. Keeping karting alive and well!

[@jakethesnake3451]

Hilarious episode! Anxious to see the dual carbs seems legit

[@colintotalfishing5374]

Hi I have been looking at your videos and it's amazing what you do I'm 66 years old and always been interested in mechanical stuff keep doing vidios they are great Colin from England

[@JedaElectronic15102016]

Wow, nice job guys! I think your next goal should be making a minibike frame to fit another v-twin beast like that, and have a race with the "Black Widow"! Sounds good, isn't it?

[@jaybyrd1935]

Holly Smokes! I LOVE IT! I'm customizing a Coleman Mini bike and thanks to you guys I'm completely changing my plans, but thank you! My bike's got 26" ape hangers on it now, I'll have to go to "drag bars" after seeing what a "stock" 670 can do WOW!

[@austinmaclean801]

Yall's channel has come a long way. I look forward to the Monday uploads. Keep it up!

[@stephentroyer3831]

With every video, the cart fits the name better and better. Great exhaust, paint, and I'm looking forward to seeing the dual intake setup.

[@TRX450RVlogger]

You should Turbocharge that thing with a small VZ21 or RHB31 Turbocharger and use a 45mm FCR Carburetor in front of the Turbocharger so you can run the 1 Single Carb as a Draw Through with a Turbocharger in front of it and just run a Pipe to each intake.

[@gratefulRed69]

that Black Widow looks like a blast! Love the rumble that thing makes. Keep up the cool work!

[@isaacitllbefine7231]

+gratefulRed69 thanks

[@MrHondatrxex]

Love the show. I believe you two make a great team and should not change the formula of the show. keep the builds simple and affordable so if the average Joe wanted to do something similar they could.

[@isaacitllbefine7231]

+MrHondatrxex thats what we plan on but we also like a little over the top too which costs money.

[@satelite990]

This got the be my favorite video so far. I'm 41 years old and a few months ago, thanks to you guys, I bought an old go-kart. What am I suppose to do with this thing now? Gee thanks. LOL

[@isaacitllbefine7231]

+Victor flores sorry buddy. lol

[@jeepcollector91]

With the river so close, I would love to see you build a Predator powered homemade boat or maybe an amphibious go-kart???

[@isaacitllbefine7231]

+JeepCollector91 are you reading my mind ?

[@Butters_Stunts]

You know it's a good vehicle when fire comes out the back

[@vicsmotos3702]

I think y'all should extend the frame forward and skinny it out in the front, make it look like a little dragster

[@alexconnerconner8130]

The two pointing up with a maybe home made chrome exhaust tip would make it look awesome

[@Spac8]

love your channel guys, really do, great fun to watch! why don't you weld a few drilled baffles into the sump to stop the oil surge you got turning into the drive? :) keep up the good work guys!

[@2cwik4u104]

great vid guys. exhaust came out sick. can only imagine the sound. a drift trike would be awesome.

[@LouSpowells]

My recommendation: Between a go-kart size and a smart-car size. One person go-kart style build based on a Golf Cart chassis, with suspension and a motor beefy enough to spin the tires and take a lap around an auto-cross course. Goal to shoot for: Set a lap time with the Miata at an Auto Cross course. Beat the Miata with the crazy beast.

[@LouSpowells]

...step two: Travel to the West Coast with the "car" and challenge Roadkill to a golf cart framed, harbor freight powered auto cross cart race...invite viewers of both channels to compete. ??

[@rgw6031]

Don't forget it needs one of those little turbos they make for scooters

[@stroudcook9647]

Please this would be awesome

[@smallenginedude71]

+Zackster698 removing the governor is risky enough on these engines. it can damage them. adding a turbo would kill it unless the engine was reinforced, such as adding stronger pistons, better rings, valves, camshafts, pushrods, and connecting rods.

[@canoe365]

I want to put one of these engines on an ultralight aircraft. Replacing the 2-stroke Rotax with the Predator will add some weight and reduce power, but the reliability and fuel consumption should improve. And it's about 1/4 the price.Thanks for showing some of the internals of the engine, and for your ideas on improving power.

[@s14duma]

hell yeah guys! BADASS. I remember when I found this channel only because of the '9 reasons to buy an old go kart' video. I was so stoked on how fun you guys made go karts look and I wish there was more content/ coverage on youtube of modded and home made go karts, but I'm completely fine with you guys doing the job pretty much on your own on youtube! true pioneers! Glad I can be constantly motivated to get my own build going while watching you guys, and I hope you guys continue to grow! thank you for the girly laughs and being the only go-kart badasses on youtube!!!

awesome videos guys. well I am just about to start an all wheel drive drift trike project...pedal power on the front wheel (so its legal to use anywhere a bike can be used) and a 3000 watt rear drive system to really have fun with. the nice thing about electric power is the immediate torque off the line like your black widow.keep up the good work!!!

[@isaacitllbefine7231]

+rodman23t good luck

[@raymondj8768]

you need to mount a camara by the exsaust so e can see the flames dudes love the vidios you guys are sick lmao

[@KevinArmstrong4154]

on the Briggs you put a couple of washers under the valve springs to raise the pressures, making sure they don't go coil bound. Good idea to fit steel or machined alloy caps if the originals are cast, easy way for more revs

I'd love to see someone use a yz125 engine and transmission and make a shifter kart that goes off road if that makes any sense haha.

sounds awesome if you could neck the pipes up to 2" it would sound like a HD. and tween carbs would be so awesome and eazey as heck to do.

[@jonathanafrica3150]

Best thing to do would to build an equal length 2 into 1 exhaust for this. It'll add lots of torque on the low end and if you're going to change the sprocket, you'll need it to get up to speed!

[@baileycox2795]

For the intake and carburettor problems, I recommend a gx390 / or a predetor 420 carburettor for each cylinder with pod filters! Would be fast!

[@yoitznoah]

A go kart that has gears. Like a kx 65 motor on one. But a drift trike or go kart with suspension would be cool. Love the videos guys makes me wanna build a kart. Keep it up!!

[@GuitarGuys7299]

Awesome build! Thanks for sharing it. It's always cool to see something with way more horse power than it needs. And then it's usually not enough. Remember kid's, "There is NO Replacement for Displacement"! BTW, Any plans to take it to a drag strip? It'd be neat to see what kind of real word 1/8 mile E.T.'s it would get. And how about a mini drag bike with a Predator 670 for your next build? It would insane of course, but fun! Or even a twin 670 drag kart with big wide rear slicks. Could you imagine 1340cc's of pure go kart madness? "It would be fiiine"! Also, since the kart is named Black Widow, metallic red rims would really set off the Black Widow theme. And I'll be joining Cars Amino and posting pics of my toy. I have a 1974 Alsport Tri-Sport RTS-SL Rat Trike converted to off road with a Rockwell JLO 440cc twin cylinder two stroke. Edit: I forgot to ask. Without using mufflers or a X-Over pipe, do you have any rich fuel mixture problems on the 670? And since the governor is removed, any plans on installing a Billet or similar flywheel? And as for the crank case / air / fuel pressure issues, running a single or dual Mikuni carb's and a pump would probably solve it and give you a gain in H.P. Arc Racing dot c0m has a great inventory of performance twin parts. Check them out. They may have some cool stuff for the 670.

[@ZacharyFlory]

I've noticed on this video more than others, that the rear sprocket sits pretty close to the ground. wouldn't be a bad idea to make a skid plate out of some diamond plate.
