Gx-390 on a 4 wheeler frame

[shakey0818]

I have an Gx-390 Honda 13hp engine from a power washer with low hours on it.I am having a hard time finding a off road go cart frame in RI.I think it may be easier to find a $ wheeler with no engine at a junk yard or something.My question is will this engine be powerful enough to run it.I am 5"10" and 200lb.Also what cc muter size would a 13 hp be compared to?

More than enough power.
Take that engine and a 40 series torque converter setup, and the right gearing, it will be a force to be reckoned with.

 

[CaptCanadia]

That is your best answer right there. I'd like to say a gx390 is about 400cc.

 

[CaptCanadia]

Actually...now that I think bout it I think the 390 means 390cc. There is your answer!

WAIT! Before you go about buying anything, make sure that the motor has a straight shaft about 2.5"+ long. It may be too short and/or tapered, thus not practical on a kart as it sits.

Its against the law in RI to ride anywhere but privet land.There is a big park behind my house now that is closed allot of grass and a big parking lot and road.Your welcome to ride here.My path to the park is rathor narrow so u might have to go to the end of the street and down the beach or we can find another way.

I took that cart i bought off you all apart and painted it real nice.I haven't put it back together cause when i tried to bring my laptop out to look at the before picts i took i busted the screen.I will try to put it back together soon.I will probably sell it for hopefully a good profit and put it towards a buggy style cart for my HP motor.

If you want me to call u so u can have my # i think i still
got yours.

I measured it and it is 1" in diam. with a keyway no taper. 3'' long to the point it gets a little thicker and then another inch.

 

[CaptCanadia]

That is what you want.

 

[j.concepcion54321]

hey, yeah thatd be great if you can give me a call, i have a new number though so ill PM you. Thanks.

 

[shakey0818]

I got it Josh ty.Call me we will set up a time to meet and fig a way to fit ya cart through my path.Maybe if ya want ill pay you to help me put my cart together.It might b fun havin someone to build with.Not too many people into carts that i know.

 

[shakey0818]

I have see many builds on here and i havent seen a thread about this.Can any1 point me in the right direction.

It's unlike building a kart, just a higher center of gravity.

• Rolling chassis
• Engine
• Torque Converter (with belt)
• Jack shaft
• Sprockets and chains
• Throttle and brakes

Would it be able to keep up with a quad? To an extant?

I don't see why not with the right gearing you should get 40-50 mph out of it.

Yes, I know that part isnt too hard... but what about low end, would the TC be enough?

 

[redsox985]

If you really want to keep up with a quad, try a CVTech TC. They have a lower low and higher high than Comet 40s, IIRC.

 

[B.M.800]

betcha them aint cheap...

 

[redsox985]

I certainly wouldn't be against it!

 

[B.M.800]

Where would one go about finding one of them anyways?
