250cc to much Power???

[mrmantis]

Hey all ive decided to make a go kart,

One of my mates has extremely kindly donated to me a good condition 250cc motor bike. I plan to strip the engine out an attach it to a go-kart, i was wondering however if the 250cc engine, probably about 45Hp, is just a bit to much of an overkill for my project, and If any one knows what sought of sound barrier breaking speeds i could break on this and what they would be. please let me know, or if anyone has had any succes with such a powerful engine.

Thanks heaps,
Max

i have a 400cc on mine. so if you die, ill die.:Angel_anim:

if you have a roll cage and seat belt set up properly then you've got nothing to worry about

hell no thats not to much power the more the better make it scream.i know thats what im going to do this summers project.

You should be good to go. It's only as fast and powerful as your throttle hand! (Or pedal!)

I dont think its 45hp, unless its one of those new kawasaki ones.

yeah just add an extra pillow block bearring to the axle and go for it. I dont think theres such a thing as to much power. is it 2 or 4 stroke?

Hey again,
Firstly, ive been on the website for the motor bike and it is rated at 45Hp. Its a 4 stroke. Its done less then 50,000 k's as well. The bike ill be using is in perfectly good condition, except it needs a new fuel tank wich is easy fixed.

Im welding the frame myself aswell, and i was wondering if anyone out there has some specifications or design templates for a frame with a roll cage?

Any way, thanks for all your support and keep you posted on my progress.

Cheers,
Max

I have a two cyl, Kawasaki 400 on a Mosskart frame. I wear a helmet & Depends!

what kind of bike is the engine out of?

 

[modelengineer]

Im getting a 500cc twin which makes 47hp... what the hell kind of 250cc makes 40hp? Only a 2-stroke, methinks.

But yeah, 250cc is IMHO the best engine size for a road kart.

Please, details on this 25 making 45hp, sounds like a race bike to me.

What the hell kind of 500cc makes only 47hp?...JK...

Haha, nice one. Yes, it is pretty unstressed. I think it has a 9.0 - 1 compression ratio which is pretty low for a bike.

It's a 2007 GS-500F with 9,500 k's. Parallel twin designed in the 80's. One of the most reliable and maintenance free bike engines you can get.

Did a bit of research. At a guess, is it an old CBR250rr? They make 39.5 hp (40 ps). 250cc 4 cylinder which revs in excess of 18,000 rpm.
