I'm am very new to the whole go kart thing. My brother gave me his go kart tho so i figured nows the time to learn.It has a 6.5 hp Honda motor on it with a 3/4" shaft.It has no tires on it but ill probably put some 11" tires on it. And it doesn't have a sprocket or clutch or chain. I would like to know what kind of clutch sprocket and chain would be the best bet.Im looking fora balance of acc and top end.but a lil more torque would be nicer then the speed. I would appreciate it very much if i could get some info.

several feet of #35 chain with a master link and chain tool, 72t #35 sprocket with either a 1" keyed hub if you have a live axle, or a 72t #35 sprocket that bolts to your wheel, then a standard 12t #35 chain, 3/4" bore keyed centrifugal clutch, you will also need i think its a 5/16"-24 1.5" long screw with a fender washer, if you need links for parts or clarification of the above just ask :thumbs up:

links would be nice lol

5/16"-24 1.5" long screw with a fender washer, first of all i have no idea what that is.lol Sorry im so new at this. Links would be nice. i don't have a live axle my sprocket just bolts to my tire. I found a 66t, not to question you but why would you use a 72 instead? I appreciate the help.

get your parts here, http://www.bmikarts.com/index.htm
do you alredy have the the tires and sprocket? find out what type of chain you have useing this link http://gokartsupply.com/chain.htm, the bolt (i guesse i called it a screw, oops) can be picked up from any hardware store, so can bolts to mount your engine. a 66t vs a 72t sprocket makes no difference as long as you change the size of the clutch sprocket, its all about ratios, here is a handy calculator http://www.diygokarts.com/speed-calculator.html, find out what ratio you want, remember the faster you go the less power, 25mph top speed should leave some decent power for you.

I do not have a sprocket or tires. but im probably going to get some 11" tires. im not exactly sure how fast i want to go. id like to get at least 25 out of it but id like to have enough torque to spin the tires if i needed to. i went to the calculator and the set up with a 72t and 12 t doesnt give me very much top speed. is there a better combination i could work with? sorry about bothering you so much. i appreciate all the help

don't expect to spin the tires on pavement over 10mph anytime soon, if you upgrade to larger size tires or get a smaller rear sprocket you can increase top speed, but it takes away power, another easy way to increase top speed is removing the gov.

Ok last question

I would be interested in probably removing to governor anyways so if you could point me in the right direction i would appreciate it. ill probably just get the 72t and the 12t. maybe ill just get a new motor when im ready for more power. i appreciate all the help.
Thank You

i would suggest you get part bundles because you save $$ and headaches from parts that don't fit.
