Building a Go Kart: Part 2

[TheDustinwalker54118]

You didn't have to buy a whole new block you could have bored out the cylinder and taped in a piston sleeve

[123frederikt]

@TheDustinwalker54118 True but then I would have to get one of those super percise thousand dollar engine hone lol, but your right!

[TheIdkusername]

were did u buy ur wheels at?

[123frederikt]

@TheIdkusername these tire are dunalop race tires that I got off ebay. The rear tires are a massive 10" (diameter) by 10" (wide) where as the front wheels are 10" by 6"

[edgarstheman22]

are you a millonare????? how do you afford all of this???

[123frederikt]

@edgarstheman22 I wish i just spend alot of money on my hobbies lol, in the end it kidna became a money pit lol. Atleast I got some enjoyment out of it!!

[Jakeyboyshow]

Great job buddy, really detailed and systematic process shows you learnt alot; Was this vid made as evidence for a College interview or something? Hope you thanked you Dad for letting you use his tools for the job!

[123frederikt]

@Jakeyboyshow Yeah this was supposed to be for the college reps because I put a link to these videos in my essays but I dont know how much it actually helped lol.

[minibikerider1]

@123frederikt do they have a hemi piston for this thing same with head?

[indyracer05]

Nice job, im new to building a go kart and am curious to see most go karts only go around 45 mph top speed. Is there anyway to make it like 55 or 60? Does the amount of hp matter? Whats the difference from a 6 hp motor and a 12 hp? Again im a n00b X)

[123frederikt]

@indyracer05 Well top speed is usually increased by the gearing ratio, because go karts generally have a clutch with fixed gears you can swap them out for a higher ratio. For example on a bicycle that has gears you go the fastest when the gear on your pedles is large and the gear on the rear wheel is small. My go kart has a 12tooth driver on the engine and a 60tooth driver on the axle. If you increase the gear on the engine from a 12tooth to a 18tooth you will gain a faster top speed.

[123frederikt]

@indyracer05 Horsepower isnt really what you want to worry about its torque. Horsepower is actually calculated from torque The amount of torque an engine can produce is basically how hard it can twist the axle around. The harder it twists then a) you get faster accelleration and b) you can get a higher top speed because the engine can twist the axle harder moving the wheels faster at lower rpms. Larger displacement engines (more cc's) have more horsepower and more torque.

[123frederikt]

@indyracer05 check out this site, it might help you out Also because your so close to the ground and in open air, going 45mph makes me crap my pants ha ha. Most go karts dont have suspension either so every little bump feels like your gonna crash. My recomendations are that unless you have a smooth pavement track I would worry about accelaration rather than top speed.

Good luck!! -Fred

[123frederikt]

@indyracer05 stupid youtube doesnt let me post the link, basically google go kart gearing ratio calculator and you'll find what your looking for!!

[racemann7f]

Wow ur fucking retarded a paperclip, Mann

[Armaangandevia1]

why not ise 2 electric motors ???

:)

:0

[123frederikt]

@Armaangandevia1 I thought about that but comparitively gasoline engines are loads cheaper, and @edgarstheman22 in not a millionare lol

[leafyism]

So, how much did all that set you back?

[alexsuchapimp]

dude you would put a tail on it!

[alexsuchapimp]

dude your dad sucks at making go karts!

[123frederikt]

@alexsuchapimp actually I built and designed it myself!! All in a days work lol it needs some improvements though.

[briggsfan101]

its pronounced "dyna-mom-eter" not "dy-nam-o-meter"

[TheMrcod5killer]

My tourqe coverter broke,and I put a Clutch on it and now the engine stalls and dont have the power it used to have.Plz help

[123frederikt]

@TheMrcod5killer Hmmm well it depends on what kind of clutch you have in relationship to your engine. Make sure that the clutch is rated to take the amount of horsepower the engine puts out. Also a thing to consider is gearing, it sounds to me that your engine is stalling because your gearing is too tall, If your clutch is mounted on a go kart then I would recommend a 12tooth driver on the engine and either a 60 or 72 tooth driver on the drive shaft.

[123frederikt]

@TheMrcod5killer Ive read that torque converters give better acceleration but lower top speed compared to centripidal clutches. Another thing to note is that some clutches designed for racing applications have adjustable engagement speeds that can be set by either tightening, losening, or replacing the springs. It could be that your clutch has an engagment speed that is set too low. If worst come to worst buy a new torque converter!! Tell me more about your specific set up maybe i can do more!!

[picapop12345]

u didsnt build it u assembled it

[Gibsongoblin]

noob question what exactly does the clutch do brake,exelerate what the heck does it do?

[123frederikt]

@Gibsongoblin The Clutch opperates much like a clutch in a car, it engages the engine to the drive train. With out the clutch everytime the engine is running the wheels have to be running to. So the clutch allows the engine to idle while the go kart is stationary, when the engine gets to 2400rpm the clutch engages the engine and the wheels allowing you to move. This clutch is centrifical meaning that it spins up to a certain speed before engaging. Thanks!!

[george2011k]

@Gibsongoblin say you turn on your go kart engine would you like for your go kart (or car) to start moving? obviously not so that is what a clutch is used for. as the crankshaft turns at idle it turns the inside part of the clutch (the hub) as you press on the gas a the hub turns more and more you have more centrifugal force so there are these springs that allow the hub to expand the the hub expands so much that it starts rubbing on the part that is separate from the hub (1/2)

[george2011k]

@george2011k (2/2) the part which is attached to the chain which in turn is attached to the wheel. so the crankshaft turns the hub making the hub expandand rubbing against the outside part that is attached to the wheel.

[pivotboy63]

instead of buying a new block, you probably couldve had the original block bored out and gotten a bigger piston. probably wouldve been cheaper

[123frederikt]

If you have the right equiptment then yess, but I dont unfortunetely so I just got a new clone block for like 50 bucks

[georgy3030]

Chrome Moly? or Chromoly push rods?

[123frederikt]

@georgy3030 Chromoly push rods, the same that Affordable go karts or nr racing sell



[georgy3030]

@123frederikt might wanna fix that in your video, because that can really confuse people

[RunsInRacesJoe]

Loss of compression from corrosion makes sense, but a paper clip causing it?

[Imsodamnhood]

u kno the top speed for your kart dude?

[123frederikt]

@Imsodamnhood my top speed is around 45 mph with a 12 tooth driver on the clutch and a 60 tooth driver on the axil

[bermorsk]

please can you say were do you get the plans for your go kart

[123frederikt]

@bermorsk I designed the go kart myself from scratch

[123frederikt]

@pivotboy63 With these mods the motor is probably putting out around 14 hourspower.

[pivotboy63]

@123frederikt how much do all the parts cost im building one and im curious

[123frederikt]

@pivotboy63 I spent alot of money on this especially the engine, but all in all minus the engine I would say like 500-1000$. 300$ for parts (steering, axil, tires, clutch, ect.), 100 Dollars for steel, and around 130$ for the engine

[pivotboy63]

@123frederikt if you had the block bored out it wouldve given you more power than just buying a new block with standard bore

[QUAN1999]

good job!!!!

[123frederikt]

Ohh you mean the Dynometer? Yeah I havent finished the video or my dyno yet. I have most of the hardware built so im thinking maybe 2 weeks?

Thanks!

[asg3131]

@123frederikt well its 7 months now :P

[123frederikt]

@asg3131 Ha ha your so right. I built the Dyno But I couldnt get the software to work so I never finished the movie lol. Maybe at some point I'll finish it just for you ha ha

[musician1232]

you have no vid on that meter thing

[NewHeadGasket]

@musician1232

yes i am interested in that thing too. please put video! i build go kart too and i want to know how much HP my go kart have! :)

[iAmCaRTooNz]

Well there's a lot to explain. Do you have texting?

[iKnowWhatisBest]

Hey, when you get back on. Can you help me? You seem to be posting a lot of comments on the Magic of Making Up videos & I'm in need of some help.

I can't live my life without my ex & I don't have money to get the advice people get with that book. So do you think you can give me some advice?

[123frederikt]

Absolutely Id love to help!

Alright so the first thing you need to do is tell me your situation and what ever you do dont initiate any contact with your ex until we figure something out! It really is key and a mistake I made. So try and stay away from your ex for the time being!Thanks Fred

[pivotboy63]

cool good job

[123frederikt]

Thanks I appreciate it!!
