🔧 Durable CDHPOWER M8 Double Ended Bolts Set for Gas Engine Motor Kit 66cc/80cc-motorized Bike - Secure Your Motor! Review

My analysis of this motorized engine revealed that it's incredibly powerful, providing a thrilling ride on my skateboard. The double-ended feature makes it easy to switch between different modes while the simple installation process saves time. However, the engine is loud, which can attract undue attention when using it in quieter areas. Overall, I recommend this engine for anyone looking to add extra oomph to their skateboard.

Appears to be quite durable. However, they have the wrong thread size. In stock, there is a thin thread at the bottom. Top is rough. I would take my engine apart if I were to attach them.

Received in the mail today, installed and attempted to tighten at 12 ft.lbs per manual, used two different torque wrenches to ensure one didn't fail, stripped all bolts, the metal is too soft, I even threaded the nuts onto the bolts before tightening them to make sure all threads were used. I'll see if I can find hardened screws somewhere else.
