newbe here, great sight....I am goin to attempt to put a ninja 250cc motor in my 1988 marathon I am thinkin I should go with a live straight axle similar to a go cart but cant find one to handle the hp's I think the ninja motor is around 30hp Ive looked everywhere where can I find one?

A guy on here used one, 1" shaft should take it fine otherwise get an ATV rear. I just read a post here a while back the parts were cheap, from a gokart place iirc. The MC motors are not bad breaking stuff unless you drop the clutch.

I use the cart mostly for off road so I am afraid of bending a stock go cart axle

its not likely that a 1'' hardened steel go kart axle will bend but it would be a good idea to have many points of support, not just the two pillowblock bearings you see on most go karts.
