Here is a Picture of the Honda GXH50. As you can see. It is the same.. No bend in tabs for the connection rod bolts. I have removed the bolts and there was no loc Tight holding them in. Only proper torque specs. IF you use the Honda or not, these motors were designed to run 3600 RPM all day and night. If you run your motor for faster speeds longer, you can over heat the end cap and rod. This over heating and then cooling over time can loosen the end cap bolts. What we have done for Titan is put in a small oil Groove into the end cap and rod to allow for extra oiling to help keep things cool during sustained high speed runs. This is not done on any of the other motors that I know of. The Fact that the Honda has a governor to keep RPM max sustained at 3600 is the key for long life. Since we are using these motors for Bicycle assist, means we want much higher Speeds and RPM's. RPM's these motors were not originally designed for. So.. We are adding and making stronger certain key parts. Normally, I never use Loc Tight. But for this application, it may be a good recommendation to make. Added Oil Grooves should fix any lube and heating issues which should keep End Cap bolts in place. If not, Loc Tight may be the next add to the build. A Bendable Tab would also be an option. I am not sure what performance degradation would occur by adding a tab and the small weight associated with it. Any added reciprocating mass would hurt performance and cause vibrations. But. It will be something to look at if any large problems with End cap bolts occur. So far.. I only know of 2 engines where end caps bolts have come lose. Yours is one. Enjoy the ride..
