Anyone with GO KART building experience :)
 

I wanted to build a Gokart using a 600cc or 1000cc motorcycle engine.
Anyone wanna help?

I always wanted to try this too! The thing that has me stumped is that you wont have reverse. Going forwards would be super fun and fast though. My brother just got some new toys in the garage so I'm always thinking of new projects to try and do.

If I were closer I would in a heartbeat. I taught my son how to weld a couple years ago and we flipped a bunch of gokarts, made out like bandits.

My advise would be to find a race kart chassis and just stretch it. They're designed to much larger stress loads than a standard kart

Tell me im reaching for the heavens here, but im trying to make something similar to a BAC MONO. But with a 1000cc engine and hopefully 700-800 pounds max. Im gonna need an engine and a differential, the chassis i guess i would hehe, copy the mono's to the best of my ability.

I guess with a motorcycle engine i would get no reverse haha, but hmmm could you do paddle shifters with it? I dont understand how to do the gearing in terms of conversion to a four wheel kart.

Find a FSAE (formula SAE) car at a local university for sale. Remove the 600cc motor and swap in a 1000cc motor. Add lightness and enjoy.

I didn't even think that as a possibility lol. I'll look into it, but iono the joy of making your own

We have a Geo Metro that we race in 24hr of Lemons that has a CBR1000rr motor

How deep are your pockets? To do something like the Bac Mono will take some $$ For an engine. Look into a junk yard for a 1000 'zuki motor. Parts for them are easy to get. ;)

Depends on you fabrication skills and tools/equipment

Back when I was a kid, we would just stick our legs out the sides and push back with our feet. Those were small, light karts with lawnmower engines.

Dude. You in no way need that size of an engine. Or that much weight. My kart weighs about 175 lbs. and with a 125cc (26 hp) engine will do 75. Shifter karts with a 250cc moto engine (42 hp) are pretty much uncontrollable. 0-60 in less than 2 seconds.

The engine is the easy part. The chassis / ackerman, etc. is the hard part. Becasue a kart is direct drive, solid axle, the chassis has to be able to twist to lift the inside rear wheel off the ground to turn it. If not, you're stuck going straight (or will overload / bog the engine with every turn).

That's not a go kart then, that's a mini race car.

I guessing the difference would be a narrow front or a 2:1 rear:frot ratio to help with torsion. Something similar to the ATOM vs a 1:1 box chassis.

Didn't you already have a thread about this same idea where plenty of people told you what you needed to know?
