curious clutch

[luckyluckey]

I know the term "you get what you pay for." So I'm curious
If anyone knows how long this clutch lasts or how well it works?

That clutch should be able to last you for many years depending on the gearing of your kart. If you gear too high it won't last very long (but then no clutch will). What gearing do you have now? For a standard 6:1 ratio, you will need a 72T axle sprocket.

For a standard 6:1 ratio, you will need a 72T axle sprocket.

Good advice if tire diameter is 10 to 12 inches.
Larger diameter tires require a higher ratio. Say 7:1 or 8:1, or higher.
Reaches a point where a torque converter would be required.

Thanks Russ, you are correct. I should have asked for tyre diameter

Max-Torque has been around for quite a while..... It's a great clutch......

Alright my tires are 22x11, axle sprocket 48 tooth and that clutch is a 12.

Indulge me for a moment...

Ignore what is printed on tire.
Take a measurement with a ruler from ground to top of tire.
What is this measurement?
It sounds like a centrifugal clutch may be wrong (by a factor of 2) for your current setup.

If I already have a belt driven pulley on my crankshaft, would I still need a torque converter or could I use a jackshaft?

Also 18" top to bottom.

 

[Russ2251]

A properly setup jackshaft system will work.
Your original question regarding max-torque centrifugal clutch will not work unless you have an impossibly large driven sprocket.

 

[luckyluckey]

Here is what I mean.

 

[luckyluckey]

The sprocket inside is a 9 tooth.

Thank you, you're helping me understand a great deal.

 

[landuse]

Yeah, your gear ratio is waaaay to high for the size of your tyres. With tyres that big you are going to need at least an 8 or 10:1 gear ratio.

Shoot, I can't get a bigger sprocket either.
