Some advice on CAG performance rebuild parts

Hi guys,

I am planning on rebuilding my bike this holidays, it has a 49cc cag motor. Has anyone tried either of these head/pistons kits before and which one do you think would be better.

From what i can see the one from pocketbikeparts has boost ports and a full circle crank, the other one from motorworks increases bore to 50.023cc (so a small upgrade)

heres a link, let me know any info (if youve had one, heard about one)

The first one is a std barrel... most likely 49cc as 12pins dont increase your output as far as i was aware. Unless its a zh, sy or sanren barrel..it will most likely be crap.

Your second option is a far better option for power. plus the forty heads that pocketbikeparts use are also great for compression. plus it says the barrel has been machined which it may have even more compression!
