KFX 400, Changed the starter clutch/one way bearing, who ever did it before me messed up the threads on the crank. I was a bit nervous to tighten it to much so I did it by feel and after 30 min of run time it sheared the flywheel key off. I replaced the key ran a thread restore over the threads and got a new nut. I put locktite and torqued it to 50 LBS this time ( Spec is 80 something ). Do you think this will be okay? I was nervous about going much further and stripping the crank.
