Hey guys I think I have asked this b4 but I will try again. I have an old 80’s autisa kit here, which according to the specs it came with will give 14-15 bhp bolt on, however it has a couple of gouges in the bore (somebody forgot the circlips) The port layout is pretty much an enhanced standard. What aftermarket piston do you think would be the best bet for it? I was thinking polini but after checking out pinascos specs it seems that of all the kits this one has the closest port layout to standard
Any thoughts?
