Big Bore kit for 140cc

[Yamah_arider]

does anyone know where i could get a big bore kit and how much it would cost for my pitpro 140 bigfoot?

also, is a big bore kit easy to fit or do i have to take it to the bike shop to get it installed?

thanks

it's pretty simple to install, if you're not confident doing it yourself then send me a PM I'll do it much cheap than the bike shops

this is about the only off the shelf big bore kit around unless you go custom from akunar.

60mm BBK would be great for power but no so good for reliability as the head gasket ends up being pretty thing near one barrel stud....

fitting is pretty straight forward....but i would recommend ordering a thicker head gasket from akunar to lower the compression down to around standard...
