wel, we'v decided to swap it to a live axle setup with a disk brake, and run the centrifical clutch, this is a dangerousely low budget build, i knw we won't get the most outta the engine, but, oh well

 

[modelengineer]

Live axle will be much better than a diff IMO.

yah, i would do a friggin torque converter, but $ is a big problem

 

[fasterthanyou]

the frame is all stripped of paint and gonna get primed soon, we put the live axle on and it looks good, gotta modify the hubs a lil, spark plug for the engine will be in soon so we can get her runnin, we found a gas tank, its just gonna run the centrifical clutch till we burn it up, if anybody knows what the stock clutch is for the kohler k309 is please tell me, i;d like to run the stock cvt thing, but i cn't find it

 

[fasterthanyou]

well, i was lookin, if i bought a super heavy duty racing clutch for 2 cycle engines would it be good enough to use, i can get one for 75 on ebay rite now

What is the size of the output shaft?

 

[fasterthanyou]

i'm thinkin 30mm or 1in, gotta read the manual i picked up on ebay and check

 

[armyvet]

be careful you dont wad yourself up on that thing,that this is gonna have major understeer.a 5 or 6hp and a centrifugal clutch ould be ideal on that platform.

i'll be able to handle it, haha, 5hp's are too boing and so are 6's i need power, and with the tire size, i don't think a 6 hp would get me anywhere fast

how does 22" tires with 10/22 gearing sound, thats what i have

 

[Doc Sprocket]

10/22? As in 10tooth clutch, 22tooth axle? And no jackshaft? Not a chance, waaay too steep.

 

[Blazkowiez]

With 22" tires the lowest i'd go is 10/54, and thats pushing it on the axle pretty hard.

 

[fasterthanyou]

oops, typo, i meant 10/44, lol, hows that sound?

 

[redsox985]

Without a TC? Go bigger than 44. With and you might be ok.

you read this??????

 

[fasterthanyou]

well, that sucks, cause we kinda already have a 44 welded up to the sprocket hub and on there

 

[redsox985]

Jackshaft time. 10 on the clutch 15-18 on the jackshaft then 10 to 44 on the other end of the jackshaft. If I'm thinking straight 10 to 15 then 10 to 44 would come out at 6.6:1? It's late please correct me.

 

[Blazkowiez]

Good God, my suggestion of gearing counted in for a Torque Converter... without that your only option is to fix gearing through a Jack-Shaft, and you may never be happy with the ratio.

 

[redsox985]

On my kart in progress I'm running a TC with 10 teeth to a rear of 54 on 18" golf cart tires. I know you have said anything over 15 needs a TC or ungodly ratio to move with a cent. clutch.
