any mods needed for a .02 or .05 bore?



would i need any additional jetting or carb for a bore thats .06 over or .o2 over. whats basically the largest i can get without having to get a new carb or jetting
An Overbore doesn't really require any mods. but a 60 overbore is a lot and might need a little bit bigger main jet. To be honest I wouldn't even bore a blaster cylinder that far. Because it will over heat easy and over heating leads to catastrophic failure.
