New Motor for LT 30

[obcexp]

I'm about to order a motor for my LT 30 I got good advise on here last week. WM will only recommend a 18HP Kohler for a complete package, I still will need to make alternator bracket. I want more HP the Kawasaki FD851 is 122lbs and 31.0 HP, has anyone put this on a LT 30 or 40? I have the double chains on the set works is this too much weight?
My other option going with the Harbor Freight 22 HP predator motor the price is so low that if I'm not happy with the 22 HP I'm not out that much.
Bear with me I'm a newby to the blogging world.

Is there any concern about overpowering the components if you go up too large an increment in HP?

I would also be wary of additional weight.

I think I'm good on the weight 122 lbs is close to the weight of the electric motor I took off. I may go with a small gas tank. Has anyone put a debarker on a LT 30?

I think the HFT Predator 22hp is only about 98 pounds (not counting fuel tank or battery).
