So an 8hp with a 1 inch shaft would probably be better with #40 chain?

As a few people were saying, and I'm not sure if anybody dug deeper into this aspect but do you have a governor on the engine which limits it to 3600rpm? They are on there stock so unless the engine has been changed or is weird then it should be there. By removing that you will increase your top speed because the engine will spin faster. Should get around 10mph more going by the speed calc

 

[TripleT]

Yeah i have the governor on.

I'm thinking about using bar tires on it. Sound like a good idea?

 

[chris_the_poser]

I would go with the 40 chain it tends to hold up to the stress a little better than 35 with the power you'll be laying down at least that's what I've noticed. What are bar tires?

 

[TripleT]

Kinda like tractor tires, but small. Some people call them lug tires

 

[chris_the_poser]

Ok I just never heard them called that

 

[TripleT]

Thanks for everyone's help so far! I was doing some adding of prices and found out it will be around 314 to get it going. A bit more than i was planning, but oh well. It should be awesome. Any ideas or suggestions are open as to what else i should do.

Skip the #40 chain and go for the narrower 41 chain. I ran into problems with the 40 chain master link hitting things it shouldn't have, and the chain was quite a bit wider than all of my 41 sprockets which made everything wiggle around more than it should have. It was just sloppy. Replaced the 40 chain with 41 - everything was beautiful.

#41 chain rocks - as long as you have #41 sprockets!

What size is a #35, in comparison with something else?

Parts List
Angled Fabric Air Filter

2 Unihub for brake rotor and sprocket
72t Sprocket

If i get a new clutch, with the 72t sprocket, should a 17t clutch be alright? If not a 14t should be right?

 

[chris_the_poser]

your parts list looks good so far. 35 chain similar to bicycle chain. 40 chain helps if your sprokets arent perfectly lined up all the way plus you can use 40 chain on 41 sprockets.

 

[chris_the_poser]

i would try to go smaller clutch to not burn it up

 

[chris_the_poser]

like a 12 or 10 if possible what size chain you going with

 

[TripleT]

I'm gonna go with the #40

 

[chris_the_poser]

yeah then i think you can get a 10 tooth clutch which will help it not burn up with bigger tires and it will help throw you back in your seat better.

 

[mysteryboy28]

don't go with #40, go with #41 chain and make sure everything is aligned properly!

and yeah, get a 10t sprocket for your clutch. 72t for the axle, and you'll have plenty of torque.

As i said somewhere here on this forum building a go kart with my own hands doesn't seem to me as a great oportunity to enjoy my free time. It was a really disaster when i tried it, and after this i bought a new one.
But i still continue to read with big pleasure others experience, and maybegas go kartssomeday i will do it...

 

[TripleT]

Okay, so now i will be having a TC, BUT I was gonna put an alternator on it. Now that i won't have room on the engine shaft, can i do like a reverse jack shaft sort of thing? or would that work?
