And what is this?

That's the part of the governor assy. that contained the flyweight/balls.
The gov. let loose and overspeeded the motor, and well, you know the rest.

Thank you. I have rebuild many automotive and two cucle engines but this would be a first v-twin.
In your opinion is it worth a rebuild or will i be better served parting it out?

 

I can't see enough money saved verses replacement to be worth rebuild , Especially once you figure the warranty on a new engine.

 

The more i look at it you are right. I will be parting it out. I believe i was missing(in small pieces) a few parts from the oil pump as well. I could be wrong and will double check tomorrow but that last picture may be part of the lubricating system. I do not see it in any diagrams relating to the governor

 

your at $600 (crank/rods and .050 pistons/rings) + governor assembly and your time-n-labor...who knows if part of the casting was cracked....looking at the one picture I see hair-line fracture from a bearing insert....that's never a good sight....who knows what that rod might have hair line fracture when it released. I see where it hit the side casing....probably should lap and seat new valves too and head gaskets.......then machine work for fixing the jug edges

In general I NEVER REBUILD motors that go "boom" only ones that smoke or have top-end/head problems.

$1200-1500 buys your a new motor shipped to your door... w/warranty and no other "iffy" parts....about 30% more in cost over an "iffy" rebuild

Heck you can get $10 for recycling itThumbs Up

 

I am most likely going to go for a kohler confidant can get 25hp for $950. Will most likely wait until spring to purchase.

Anyone need kasawaki parts... lol
