what a vogue??! dude those are awesome.
forget ebay man. 1977 and treats and quarterkick would be way better. look up 103 like he said
If you want something simple you can upgrade the carb, exhaust and intake. then take out three balls from the variator for more acceleration. (vogues are newer so this might be different) If you want to make a big hobby out of it you can upgrade the variator, engine case, head, clutch pulley maybe...etc
