A starter clutch failure has been the only thing to go wrong with my bike from way to much use. In the repair of the starter clutch one must remove the flywheel. In removing the flywheel my crankshaft end mushroomed! The loctite that the factory uses # 648 has a tensile strength of 4000psi and takes a lot of heat too, making things almost impossible to get apart! So now that I have spent some amount of time to clean the threads back up. I fear using the 648 loctite again if I need to remove the flywheel for normal maintenance of the engine. So the question is has anyone used a loctite other than 648 to glue the flywheel? And I would strongly suggest that the nut be left on the very end of the shaft when using a puller to give the area extra strenght. What a pain!
