I would read up on these engine kits here on the forum and make your own decision. As for your question, I will say that the basic componenets are the same, except the carb and a few minor other things. They are still a chinese engine kit in a box and you are buying a semi-unknown quantity when you buy one.
These are hobby engines, and may or may not run right, vibrate, ect. when you mount them up....but that's part of the fun.
It is like Bikeguyjoe says, some hold higher claims..............
YD (Yuan Dong) or NTJL (Nantong Jiali) factories Grubee engines.
Raw engines- Jiangdu Flying Horse Factory.
Boy go Fast engines- Rico group imports.
Grubee Generation II's claim to have a superior installation kit.
