All right so my 300 engine finally gave out at around 65k miles, the cylinder 1 rod bearing left me searching for chunks of gold in the oil pan. At the moment its looking like a new piston, rod, and crank at the very minimum plus the smaller extras (bolts bearings , rings etc) So far its looking like;

~$600+ to repair
~$900 for a used engine
~$1100 for a ninja 400 engine
~unknown $ do something crazy with a random engine just because

I'm leaning towards the 400 engine (comes with wiring harness and ecu) to keep it a little more exciting of a bike, the 300 is tough to ride after getting off my street triple R lol. My understanding is that the 400 is a stroked and bored 300 and that the case is the same, is this correct? Not in any huge rush for this and depending on the route chosen there may be some cheap internals available for yall soon.
