Clutch smoking

[Odom]

I’m unsure of what’s causing my go kart to smoke…. I have a 224cc engine with a centrifugal clutch with 10 teeth, a drive sprocket with 40teeth, 12” tires, my weight is 165, my go carts weight is approximately 100lbs I put this thing together and it struggles to even get going and soon there after like with in seconds the clutch is sparking and smoking and getting extremely hot

You need a final drive ratio closer to 6:1, right now you are 4:1

 

[Odom]

Ok how do I get to that

 

[Odom]

And the tires are 16” not 12

Cluches are the same on my go kart just get a tourqe converter with that set up there faster and dont smoke

Also there is no way that go kart weighs 100 pounds thats gota weigh like 300 pounds or more

Ya you’re probably right on the weight….. and I guess I’ll get a converter then… I appreciate the input….

Probably cuz yer a bad parent. Smoking is stress induced. If your parenting skills were better, your influence would have kept it from smoking.
Look at the bright side; its better than drinking!

You need a torque converter with a Genuine Comet Belt. And you need to mount a 60 tooth sprocket on the axle. After that you will be home free!

 

[Odom]

Ok any idea on what type or model of torque converter I should get? To match up with the engine?

A 30 series or on amazon search 224 cc torqe converter ex:3/4 shaft torqe converter (3/4 size of output shaft)(and what size chain)

Um you need to get a 30 series, a Genuine Comet belt, and rear sprocket with 60t. Or at least absolutely no less than 54t and pair it to a 9t sprocket.

Hilliard clutches just aren't that strong to begin with, they are best suited to track racing where the spend 98% of their exsistance locked... you have too much engine, too much gear, too much tire, and not enough clutch.

Final drive is the :1(to one ratio) dividend of the rear by the front...

40÷10 = 4.0:1
50÷10 = 5.0:1
54÷10 = 5.4:1
56÷10 = 5.6:1🫳 the kart is light, you are light, but it will likely struggle with hills and eat belts

60÷10=6.0:1
54÷9=6.0:1
56÷9=6.22:1

I don’t smoke clutches, too hard on your lungs. Bad for your health too!

So this one

So this one

Or any other cheap "Tav2" or Comet 30 series clone... they're all the same.
What most important is that the come with a sprocket for #41 (410, 420) because a #35 isn't going to hold... most do come with both, but others come 41 or 35 only.

 

[Denny]

And only use Genuine Comet Belts!!!!

Odom, the one you put in your post will work fine. Like Rat said, they're all the same. I have 4, from 3 different manufacturers and I can't tell the difference. When the belt that comes with it wears out, ( won't be long ) do like Denny suggest and buy a Comet brand belt. It cost around $25 and the cheapies are only $10. It very well could last as long as you own the kart. Worth the price many times over.
