Chain snapping axle bending torque

This was done with just 20hp. Might want to invest in an all steel sprocket and add an axle bearing right next to the sprocket.

The guys in this video are a little too excited so it's got some language in it.

by the way it 'lays' there.. I'd say it's a vertical shaft engine.

I'm not sure you can just mount it to run horizontally.
but if you can (or it is a horizontal engine) then as gran_pann said...
a ton of torque go get it

in my profile is pics of my running 18hp briggs twin cylinder
it runs highway speed and will do wheelies on this dingo frame with a 40 series and normal 10 to 60 tooth
there 3 pics in the first 5 of that folder in profile ...tight fit for sure ,but no welding at alland it does not bend chain or axle BUT
I HAVE 4 SUPPORT BEARING MPOUNTS AND DIFFERENTIAL
at this time its being switched over to live axle so maybe then we will see the axle bending torque but prob not with all the supports lol

BTW awesome find
mt cub cadet guy wouldve fought you for that

Please stop double posting. This has been mentioned to you before, IIRC. You double post in almost every thread...... Use the EDIT button......

EDIT sid, it's a horizontal shaft engine.... The air filter kinda gives a clue....

Now that you point it out...
It was looking like it's resting on one cylinder and that means there's no mounting plate on the base to me,
but I guess it's just the odd angle of the pic that had me fooled

Where are your pictures to? I can't find them on your profile?

However, IMO, that was only part of the problem; the bigger issue is he was rolling back when he hit the gas, creating a worse situation; the momentum of the kart was the reverse of the power; those circumstances were a disaster waiting to happen...

Is a 25 horse a good motor to have on a kart?

 

[KartFab]

A 5-7 is usually adequate. 8-13 is pretty powerful. 16-35 hp V-twins are just nuts.

 

[B.M.800]

If the appropriate modifications are done... heck yes!
You will need to beef up the frame, maybe a new mounting plate aswell.
Keep in mind, clutches will be more $$$ than the average.

Looks like that engine has 2 shafts you could utilize... I believe Doc Sprocket has a briggs engine like that

You are very right there!

On an equally strong frame, there's no reason why not...

Keep in mind, the vid gran_pann linked above is a perfect example of what not to do...

2 shafts?

What size is the shaft on this u guys think and could it supports lights?
It's probably way more of a beast for this kart...but upgrading the frame later is a option I don't mind! lol!
