Upgraded 100cc Bicycle Engine Kit - 2 Stroke Petrol Gas Motor Conversion Kit, Air-Cooling, Super Fuel-efficient, 2023

Just open my engine found out missing mount for sprocket

You must have know-how to put these kits on. There are electrical wires that are present on the engine but are not mentioned at all in the instructions. What wires are mentioned are not the same colors as what's on the engine. Photos in the instructions are awful. I'm sure my engine kit is fine, but I've been scouring the internet for hours and hours now troubleshooting things. My engine still will not start. Parts in the kit are very cheap, as they bend and break very easily, resulting in a number of annoying trips to hardware stores.

Instructions included are useless. The clutch is extremely unreliable. Parts strip easily. Motor does run and works decently.

It is overall a good kit. Everything fit well, but when it came time to fire it up, I found out the cdi was not working. So the motor has no spark, which means it will not run. I am only giving 1 star because after all the work installing the kit, and a fair bit of pedaling, it would not run.

Never used it

Great motor couldn't ask for a better running little motor
