I'm just about to put the block back on after changing main and bi-end bearings and I was just about to put the block on when I noticed that the crank won't turn clockwise a full rotation. Counter-clockwise is fine but going the other direction it's like it just locks up but not always in the same spot and if I alternate directions it will unlock and spin a bit before locking again. The cam-chain isn't binding. What could be going on here? Thanks

 

We'd need a bit more info. It could be a number of things...

I'd recommend starting a thread under the Hurricane section and documenting the work you've done and current status. Then at least you/we will have a fighting chance
