Live axle recommendation for 60hp motor

[Ogre]

Im hoping to build a fat guy sized go kart. I picked up a Harley twin cam 88ci, outputting around 60hp. What thickness of axle would I have to use for this?

That engine might be a bit much for a kart. You might think more buggy.
1¼ axle most likely. Splined stuff not keyed.
What's your plans for a frame? Find and adapt or build?
That Vtwin would make a nice adult toy but your gonna need a bigger boat.

Sounds like a fun project!

I can weld, so I was thinking of using 2x3 box tubing. It's going to have to be beefy, I'm around 260 and the engine is 185.

I was planning on mounting the engine beside me so I can jockey shift it. My tinnitus can't get any worse, so why not?

I just need to figure out a front suspension that will tolerate the weight and a rear axle that can handle the hp and torque.

Mount it behind you in the center of the chassis. It will be far better for the suspension design wise.

Okay, the Harley engine has been sold (100 more than I paid for it). Apparently I'd have had to run a modified computer for it and that's just too much trouble.

Made a hundred bucks and saved yourself some hassle. Sounds good to me.

Since you can weld you could always buy a beater 2 seat kart, stretch it to your liking. The big block industrial engines ( 390 to 440 cc's ) can be hopped up to
20 to 25 horse power pretty easily. Enough umph to have fun with. Won't match a sportster engine, but no computer needed either.
