100cc Bicycle Engine kit, 2 Stroke Motorized Bike Kit Petrol Gas Engine Kit, Turn Your Pedal Bike Into an Electric Bike (Silver)

Make sure that the jug is a one piece design. Not a two piece design to insure that it is 100cc engine and not an 80cc engine

Not a good engine drive 3 miles to work and back not beating on it at all blew up in a week before it even got broke in. Gas mixture was what the book stated horrible purchase! Waste of money!

Nice motor easy to run.. terrible build instructions.. clutch is finicky and seems to expand when hot. Might just be another piece of clutch pad that rubbed off and is spinning around in the housing causing extra friction.. also choke is a bit floppy and randomly falls down causing poor performance.. but tons of fun!

I had one of these before and I thought i'd try another. this time it didn't run for an hour before the crank shaft broke. It's a fluke thing. The nut was still on the bolt, I took it off after I got it out.

Love it works like a champ
