Help with sprocket sizes

[5trucks]

Cart weighs about 250 lbs and the engine is a 13hp clone. I am using a comet 40 series and jack shaft set up. The jack shaft sprocket is 12 tooth and the axle is 54. the chain is a 40p and rear tire size is 25". Clutch is working really hard and is sqeeking at times. The belt was adjusted according to size and it flopped around like crazy. I could take it off without even moving the drive or driven clutch forward or back. I re-adjusted it to tighten it up and it appears fine but now the center to center is out of manufactures spec. So, what sprockets would be good for my combination? I can also throw some 22" tires on the rear if that will help. And whats up with my dang clutch?

Wow..Uh yea. Lemme guess your go-kart is slow as hell? Dude 250 lbs? 25" wheels? Omg. Don't blame your clutch. It's you. You have SO MUCH **** weight and such little torque. Thats like having a hamster make enough electricity for a whole city. Not possible. Nice engine though. Make thoughs tires smaller and make the sprocket on the axle have 72 teeth.

Or what would be great also is a torque converter. but it's kinda exspensive :/

Comet 40 IS torque converter.

 

[Aryukei]

Oh. Didn't Know. No Experience with torque converters..

That thing should be haulin a$$! Ive seen full size golf carts with 13 clone move quick! and there 600+ lbs

Here is what it looks like. Help!

Dude! What size is that small sprocket on the end of the jackshaft? If you made that a bit bigger, I'm sure you'd be hauling donkey! After you find out what's wrong with your TC, of course...

 

[Aryukei]

Wow nice. Good a nice engine. Nice shocks. Nice jackshaft. Nice Torque converter. How come you have no header or muffler though?

 

[5trucks]

Stock muffler modified on the inside to breathe like a bastid. What size sprocket on the jack shaft? What could be wrong with the tc? It has like 1.5 hrs on it.

Thats a sweet Kart!!! That T.C. should be able to handle a 13 h.p. with not too much difficulty,despite any weight issues. So whats the problem again???? Not enough torque/speed or wrong sprocket size?

Get a bigger driven sprocket and it will fly. like a 60 or maybe a 72. Im running a similar setup with a CAT99 and a 5 horse (same sprockets), but with 21 inch tires.

Where can i find a 60 or 72 tooth sprocket for a 1" live axle? What about jack shaft sprocket? It's 10 teeth. I had to double check.

 

[2or3wheels]

yeah, i recomend getting a 72 for sure.

 

[5trucks]

Currently using a #40 chain. I cant find a 72 tooth #40 anywhere. Should i go to a #35? I can get up to an 84 tooth if i go to that. What are the recommendations on that? Sprocket thickness is my only concern.

 

[Kenny_McCormic]

http://www.gokartsupply.com/sprocket.htm has #40 72 tooth sprockets but with shipping and a hub your looking at at least a bill for some of them.

 

[5trucks]

Sweet mother of all that is holy! I just ordered 4 sprockets (two jack shaft, one drive and one idler), 10' of chain, 4 master links and 4 half links for $60 shipped.

I think you have your Driven on backwards, the spring should be out not in.
