Any ideas on what would be good to repower a John Deere 314? Motorcycle engine?

The problem with repowering a 314 is that for most engines you need to change from the stock drive shaft to one with U joints or modify the frame to lower the engine. Most engines have a higher crankshaft height than the K 321 which means they won't line up to the transmission without a u jointed drive shaft.

I have no experience with them but this is available.  I have considered it for my 312 because I think it would look cool hanging out the side of the hood supports. and would make it a snow moving monster with the 49 blower.  I would probably paint the red parts on the engine black or green...

Jim suggests the 18 also:

Here is a thread on another option:

I am not sure but think that 14HP Vanguard might have a bit smaller dimensions making the swap easier.

the 14 and 16 hp vasnguard are identical except the carbs same with the 18 and 21 has well the 21hp has a 2 barrel carb and the 23 has a high lift cam with you guessed it a slightly bigger carb as far as i know the block on all them except for minute differences. 

 

Awhil eback we repowered a 317 with a 20 hp honda engine with one of those repower kits and everything bolted right up except we had to put a 1 inch body lift on it because the valve cover hit the side shield but that tractor ran great and was powerful

From my experiences I was able to replace the K series Kohler with another CH series Kohler with only minor differences. The shaft adapter for the flywheel even bolted on . and they have a small package for such big power. So I would try a Kohler V-twin .

CH series is the replacement for the K series with a solid state ignition?

I don't think so? As the ignition and mounting bolt pattern are different. But it fits quite well and most of the tough stuff works right out.

I think the Magnum was the direct descendant of the K wasn't it. Pretty much a bolt in. Trying to find a good used low hours replacement for a K series isn't easy around here.

I repowered a JD140H3 for less $200 including a $140 muffler (that I ended up replacing later because it was so close to the PTO clutch the belts kept melting); plus $400 for the used used 16 hp B&S Vanguard horizontal twin.  Even kept the declutcher. 

 

Probably have sixty hours on it now with now problems at all, well except two $40 belts..
