I have been looking at a "Athena HP alloy 70cc kit" i know they wont be as reliable as a 2 ring kit, but does anyone know what the power output on these kits are like? I have heard that the port timings are quite tame but the kit produces alot of torqe? And lastly i have heard that these are the closest equivalent to the "PM tuning x teck 70cc cylinder kit"? Any help would be apreciated!
