Big Bore ported kit???

[Onebadpolaris]

Hey, Im wanting to get my x7 ported with a big bore and i saw this kit that makes it a 52cc with ported exhaust ports and intake and comes with the piston and all you need for it for like 85$ is this worth it? heres a link to it ....

said 44mm piston on the site, my piston's 44.5mm and from what i know, it's only 50cc

sounds like som b talk to me...

they mention in add the bore is 1 3/4 inch which is 45 mm so i would say this kit is a 49cc with some port mods only, check out the price of a stock 49cc barrell / piston / rings / bearing and pin then compare the difference.
the best barrell mod for performance is the machined barrell / head kit, this has a separate head /dome ect which produces the best power for any air cooled.

it's amazing how many of the kits out there are false when you look closely at the details, so be careful who you buy from.

from what i know, to get a proper 52cc you need a 44mm or 45mm barrel + a 33mm to 34mm stroker length on the crank

44mm + 34mm = 52cc

45mm + 33mm = 52cc


please correct me if i'm wrong as i haven't used this method in a while
