Hi y'all
I got an f4 that was dropped on its left side, stator cover, stator, flywheel all destroyed. I installed all the parts (starter turns over without the gear beween the motor sprocket and the flywheel). Tried to start the bike... I can hear the starter relay clicking but the engine is not turning over, took the left cover off to re-examine and realised its almost impossible to turn the engine over by hand. The service manual says 'mechanical failure' if the starter relay clicks and no movement... Is there a possibility that crankshaft got bent from the fall? I can turn it over barely with a wrench (counter-clock). I spent a lot of time putting the rest of the bike together.. Just wanna make sure before I start shopping for an engine.
Thanks.

 

Definately your crank is bent. You can pick them up off ebay cheap, $100 - $150. Lotsa work to replace it, but it could be a good winter project.

 

Thanks.
Posted same question on CL, someone suggested me i might have an hydraulic lock, gonna take the spark plugs out.
Are there other parts most likely to replace other then the crankshaft?

 

I don't think it's a hydro lock, but it's deffinately worth checking. Maybe crank bearings? but probably not. The crank is the only thing I can think that would cause that.

 

I hope it would be something simple as hydro lock.
But probably not.

 

It Works!
Charged the battery all night and took one of the sparkplugs out in the morning.
Hit the starter switch and the flywheel turned over, Mounted the stator cover back, put in oil and engine started. Drove it for 50 miles this weekend, everything seems to run fine.
Thanks for the suggestions.
