79bart

Just acquired a gen 1 brat with an ea71 and the motor was a little tight because it was sitting for years but we freed it up and got new oil in and everything but still not having any luck keeping it running and im considering rebuilding the motor. Ive already ordered all kinds of parts for doing this while they were on wholesale but im wanting to do it soon but dont really know enough about rebuilds. I have quite a bit of knowledge i just havent tackled a rebuild on my own before so i have a couple questions... #1 is there a way to get a bit more power? I have my webber coming but i was wondering what i can do with the motor apart to add a bit #2 pistons and things... do i want to go a bit bigger? if so does anyone have any advice? #3 anyone know of any good write ups for this? Just hoping people have some advice so i can get this thing done and back up in good shape! Thanks in advance!
