Once you've got all the bugs out on shakedown, the Kinetic isn't all that bad of a moped, they are simple, with a fair amount of "go" to them, and reasonably durable.
The Problem comes from Kinetic having almost NO Quality Control at all on thier assembly line, so they do require extensive shakedown prior to using em on a regular basis.
So shake it down, take apart the parts you are skilled to do so, and check them.
Oil Mix is 3% on a Kinetic, but I'd run a hair more during break-in.
As for the discrepencies, prolly due to bad translation and folks with poor math skills converting from metric, but hell, you think that's bad, read some Motherboard documentation from PC mainboards sometime...now that's poor translation !
But anyhow, shake her down real good, and the Kinetic will hang in there quite well, once you get past the break-in period.
