I rate the Chinese bike engines I've owned in this order:
1. Tiger brand, sold by Livefast Motors
2. ThatsDacs
3. Kings
That being said, the Kings is the fastest but the quality is the poorest.

Have you tryed a PowerKing lately?
I have and the differences from it's preddessor is astonishing.
The kits I'm getting from powerKing now are totally different from what they carried even 6 months ago.
For starters,
:they now have 8 mm head bolts as apposed to 6mm
:They use lower aswell as UPPER roller bearings instead of a bushing
:Much nicer throttle and matching grip
:higher quality intake manifold
:Better exhaust gasket
:The actual castings are of a much higher quality(no holes and/or pits in the cooling fins, etc.)
and other upgrades aswell.
Having purchaced 7 or 8 of these kits in the last couple months, I've had not a single problem with any of them , and the quality has remained consistently excellent.
I've had problems in the past with the quality of PowerKings kits and have stated such in this forum previously, but the kits they now carry are excellent.
I honestly can't think of a single weakness in todays PowerKIng kit compared to any others on the market and the service I've recieved from John in their Burbaby warehouse has been nothing short of topnotch.
I've just purchased a 49 cc 4 stroke kit from them.
Just installed it yesterday .
This Kit looks exc aswell.
I'm using a 44t rear sprocket from a HT instead of the 50t it came with as I havent had time to build a rear wheel around the freewheeling hub that was supplied but even with the 12 percent increase in gear ratio , it seems to have much more bottom end torque than any happpy time but this might be a dillusion on my part and don't take this as fact till i put them side by side. lol
Anyways , I myself am more than happy with the Kits PowerKing now carries, Both 2stroke and 4 stroke.
