  • Complete engine kit for motorized bicycle 100cc
Color: 100cc 2 Stroke 36 Tooth
YD100 engine kit with 50mm piston and one-piece cylinder/head. The YD100 engine kit came with everything needed to install on a beach cruiser, started right up, sounds strong and runs smooth, see video. (I used a different muffler instead of the one included in the YD100 engine kit) Note to installer: 1) add a little 2-stroke oil into the cylinder and into the crankcase - the engine comes completely dry - avoid turning the engine with a dry cylinder wall and piston rings 2) open side covers, check magneto and drive gear tightness 3) grease drive and driven gears - they come with just a dab of grease, basically dry. (change gear grease at regular intervals after good initial lube) 4) center the magneto coil around the magnet so it does not grind the coil arms 5) lubricate clutch release shaft/cover/push bar/ball bearing 6) check head studs and all fasteners for tightness - do not overtighten ... show more

Color: 100cc 2 Stroke 36 Tooth
They don’t listen to feedback, don’t give customer support. Leaks and pours gas. Throttle doesn’t work. Wires color coded wrong. Instructions are awful. Too much money for it to be defective and broken! Chain and tensioner won’t line up. The whole entire kit is wrong in every way. Nothing aligns properly. Instructions on the wires are not even color coded correctly. Doesn’t fit a 26”-28” bike. Chain pops every 30 seconds. Brakes don’t work. Nothing sits properly. Just an all around terrible buy for way too much money. Bought one a couple of years ago for way cheaper and worked perfect for two years. No issues at all. Definitely wouldn’t recommend this one. ... show more

  • Great for the price
The motor runs well for what it is, everything in the kit is all you need for a complete install. Make sure to take the time to clean stator and rotor before install as there is a light coat of oil on them and you need all the spark you can get. Also narrow the plug gap and it will run fine.
