which would give me more power?

[brsslam14]

What would give me more power? the 240cc kit with a bigger carb and a toomey b1 exhaust. or 68.25mm piston from wiseco ported and polished, and a toomey b1 exhaust? out of those two ideas which one would give me more power? or is there other things that i can do for around $500-$600 to get more power? thanks in advance!

Don't do the 68.25 piston.

Either buy the big bore, or get the stock cylinder ported. Get the Toomey and you'll be happy.

Big bore, port and the pipe

I would, port, polish, and do a head mod. Don't bore the stock cylinder unless its needed, the gain is insignificant.
