How do you bore out another 40cc

[Bencooney11]

If I want to make my blaster 240cc must I just put a oversized piston on it and gaskets . What mm piston would make it an extra 40cc??

you can't bore out a stock cylinder an extra 40cc. period.


this chart will help you understand....

Ya, stock bore + .040" does NOT = 240cc A stock cylinder can be resleeved for a 72mm piston .
At that point cost wise might just as well get a Vito's BB. Or save up lots more and spring for an Airsal or CT Sonic $$$$$
