2-stroke pocket bike engine on go kart?

[jace]

i have one of these

47cc pocket bike motors and was wondering if i put it on this go kart

..would i have pretty good speed and power. the specs say it has about 5hp the cart weighs about 210 pounds with me in it.if it would work what gear ratio would i need.?

 

[brendonv]

well it will go, but it will be crap.

 

[Rotore]

get for of them with built in cvt's like the x1 and it'll go at a dencent speed

 

[jace]

why will it be crap? the cart only weighs a little bit more than the pocket bike it came off of , the bike had really good pike up and a top speed of about 35 ? im probally going to end up puttting a honda gx160 clone on it ..i was just wondering becuase this engine would look alot better then the clone, i was thinking of doing a dual engine setup with two on these pocket bike engines but i couldnt figure out how to get the opposite wheel so spin the right way?

 

[Rotore]

ummmmmm live axle

 

[jace]

Don't want a live axle . i want each tire to spin by its self.

 

[EagleTalons]

If each tire spins by itself it with pull more to one side. Unless you have the engines perfectly synchronized. A live axle would fix this problem.

 

[jace]

okay ..but would it be better to have the dual pocket bike enigines or the honda clone? power and speed wise?

If each tire spins by itself it with pull more to one side. Unless you have the engines perfectly synchronized. A live axle would fix this problem.

This statement is utterly false.

 

[jace]

Russ, from what i can tell your the person to ask about dual engines? how would i do dual engines without a live axle?

 

[Russ2251]

There is no inexpensive way.
A jackshaft arrangement would have to be incorporated.

 

[jace]

welll i have all the stuff for a jackshaft laying around in the garage . would i just mount the motor the normal way and make a jack shaft going from the output on the engine to the sprocket on the tire?seems easy enough.but ill probaly just put the clone on it for simplicity.

 

[Flexibel_kampfe]

From my understanding:

Motor chains to jack shaft. Then the jack shaft's sprockets at each end, chain to the sprockets on the wheels....

 

[KieranM]

if you decide to put it on the kart remember that it will be alot slower than the bike, because its a different design. its possible to do it, but the fun you will have will be minimum. You can upgrade the engine by big bore kit, replacing the reeds and performance exhaust ect and it will make it better, but the truth is, that it wont be a patch on a honda or briggs.

 

[Flexibel_kampfe]

Scour the dump for a ride on/snowmobile/motorbike/et cetera. Sometimes people throw out perfectly good things, because they upgrade, or something as small as a spark plug is shot.....

Since a 2 stroke pocket is junk for these beasts.... chances are the hp is miniscule...

This statement is utterly false.

Pretty sure if one of your rear tires spins faster then the other rear tire and the front end cant keep it straight it is going to pull to one side.

 

[Doc Sprocket]

I suppose that pulling would only be an issue if there was a gross difference in power from one side to the other.

how many cc's and hp's does your avergae lawnboy,mac,homlite have becuase ive seen tons of people with those kind of engines on a cart?

 

[Russ2251]

how many cc's and hp's does your avergae lawnboy...ive seen tons of people with those kind of engines on a cart?

Current L-B's I use are 141cc's. Factory spec HP is 6.5. My actual HP (after light mods) is unknown. Could be 8 or 8.5.

P.S. Where else have you seen a Lawn-Boy powered GoKart???

 

[jace]

actually a guy down the street from me has a lawn-boy powered go kart and there is a few lawnboy powered go kart on youtube.
