Thanks for the video gnarwhale. It was very helpful I had no idea these were so simple!

[PTEredmond]

could i just stick a pulley or one of them gear things right on the shaft from the engine and have the chain or belt go to the pulley/gear thing to drive the wheels? what happens if you don't have a clutch one more question do you want a big gear/pulley thing or on the engine or a small one in order to get maximum speed? thanks :) im new to this

[gizmoguyar]

@PTEredmond Without the clutch the vehicle would always be moving. The clutch "disconnects" the engine from the wheels when the engine idles or is at low RPM. So the vehicle can be stopped and the engine keep running. Then when you want to go, you rev the engine which "engages" to the wheels, moving the vehicle.

[gizmoguyar]

@PTEredmond Maximum speed would be obtained with a large gear on the engine, and small gear on the wheels. But the engine spins too fast and doesn't produce enough torque to to power a go-cart, so usually a small gear on the engine and large gear on the wheels is required to get the right balance between torque and speed.

There is never a set ratio or size, it depends on the engine size and and the desired performance with the available power.

here's one for u . how many teeth do you have on your cluch and the cog on your axle and what is the horse power of you motor thank you

[matt11knebel]

how do you take the clutch apart?

[jopa29]

lol, dealing with those cluches are like dealing with ball bearings. they are so annoying

[erwer66]

is it possible to put a differential on a go kart?lol

[91redneckproductions]

@erwer66 yea buddy check out my vids u will see them i had them on mine

[rebelsoutherner]

dude i can soo hear your phone at 2:03 haha, good speakers

[hope2bmills]

hey what size bolt do you us to keep the clucth on

[buzzzatho]

what exactly activates the "shoes" to touch the drum?

the centrifugal force that acts upon them, pushing them outside to the drum? or there is an sistem in the craneshaft?

Please answer i have this doubt like forever...

Good video! please put more Kart videos like this

[ImRamro]

Thanks for the info.

I am working on a go kart with a Honda GX 160 and I can not seem to figure out why the rear tires are constantly spinning when the kart is just idling.

Well now thanks to your video I know that the engine is idling much too high. The clutch works of rpm and if I adjust the idle down then my clutch will not engage. This video has been helpful

thank you

[joostin123]

I got a STRIKE clutch for my Yamaha KT100J

[havocdaemon]

Thanks for the info, helped me out a bunch! Also, NICE STACK man. XD

[estevanruvalcaba]

so ur saying once u press the gas it will start going.............do u really need a clutch?

[DirectCore]

@estevanruvalcaba A centrifugal clutch is effectively a drum brake in reverse.

[kestelll]

it's tha same kind if clutch that's on many of the old mopeds

[jmoyet]

do you know how to maintain them? i recently got a go kart and want everything to last for a long time... although i know the tires wont.. lol

[gnarwhaleRanch]

I guess just keep them oiled.. spray WD40 on it sometimes.

[jmoyet]

i got a maxtorque TT racing clutch for my go kart. says oil the bushing about every gas refill with 30w oil.

[gnarwhaleRanch]

Well do that then lol

[mercuryblob]

hi, ur video was very helpful, i'm 14 and me and some mates are trying to build a go kart but we have a verticle shaft lawnmower engine. Can you give any advice or tell me where to buy parts or get plans, thanks

[gnarwhaleRanch]

What exactly are you making? a go cart or fast mower?

[P3mpi]

What is the best you can get with a vertical engine??

[jeas123196]

i have a question, does the engine have to power up both weels on the back? or just one side on the back?

[gnarwhaleRanch]

that all depends on your axle.

[jeas123196]

what does you mean by that?

[jmoyet]

some go karts are have 1 axel going to both back wheels and the engine has to move both wheels...

some go karts (like mine) have a separate small axle for each wheel and the engine only has to move 1 wheel.

if you rotate one wheel and the other move you have 1 axle attached to both wheels.. if only 1 moves you have 1 axle for each separate wheel.. so only 1 wheel will be moved by the engine..

[jeas123196]

making go karts with the experience of lego technic makes everything easier...

[av8rdavid2003]

Hahaha! I know what you mean when you say they are a bit anoying when the spring throws off the shoes....Its as anoying as trying to re-build a recoil pull start assembly..

Great video.

[gnarwhaleRanch]

true, but i (alex) am really good with rebuilding recoils
