I generally would stay away from using any locktight inside the motor but I have an Woodcraft cover for my busa that has an exterior skid pad with screws that install from within the cover. Also, there is a sensor that reads the generator rotor in there. The sensor is bolted to the inside of the cover also.
I think I should use locktight because I have noticed anodized screws seem to have a tendency to come loose. These are steal screws but the cover is anodized aluminum. I'd hate to have one of those screws fall out in there. That would be bye-bye busa!
So what kind of locktight? Hightemp?
