F4i no longer runs after crash
So my 04 F4i no longer runs after a nice spill on my own damn block.
Long story short I lost my rear end, bike went down on the left cracked my stator , stator cover AND my case right behind the stator. Oil and coolant leaking all over, pick it up roll it back to my house and so begins my rebuild. Case was fixed with jb weld that's held so far , granted I haven't gotten the bike to start since the accident.
stator replaced , stator cover replaced. Figure awesome she'll start right up, nope. Key in, dash lights up, bike in neutral, kick stand up, clutch in, hit starter *click* , one click, dash goes out and stays out as long as I hold , pops right back on as soon as I let go, repeat the process.
So i do my research, f4i's tend to get hydrolocked when they sit on its side (was only about a minute AND the tip sensor triggered which cut the engine) , not likely but a possibility. Great lets pull the plugs , and hit the starter to get it to puke the oil out of the spark plug holes.
Nothing. Same deal *click*
Ok maybe it sounds to be starter related, check the relay and jump it to see if I get it to trip, it does. Ok great now I figure it's my starter motor , pull my starter motor, take apart, clean it up, put it back together , attach it to a battery to check motor runs absolutely fine.
Rear wheel spins free in neutral, TONS of drag if in any gear even with clutch pulled in.
at this point only thing I could imagine is a seized engine , completely out of ideas , help guys!!

How exactly would I hand crank it? Ratchet on front sprocket nut with clutch pulled in?

put in neutral and turn it clockwise (I think it's 17mm) it should turn with some resistance and whoosh sounds, if it's locked you won't be able to hand turn it
Again it would be really odd if the motor locked... but at least you can rule it out

All you have to do is take the timing hole cover off on the right side, you'll see something like this B0A2DE48-77E8-4A16-AC1E-9EA423804CDC-6306-0000053BF8367731.jpg Photo by Bawlzout Photobucket

Bike IS currently on a stand, even in 2nd or 3rd gear the bike has a ton of rear wheel drag so much so that it requires 2 hands to spin , much more then I've ever noticed it needed to roll it with clutch in before the crash

So as long as I'm getting some movement I should be okay, will give it another shot of spinning the tire in 2nd/3rd gear later on today, thanks for the help so far!

how would I check that ? I have definitely confirmed the starter relay and motor both work by jumping the leads and then connecting the motor to a battery, also inspected the cables coming off the relay to make sure they are not frayed or otherwise damaged
