the bottom bike has a lawn mower engine from the 80s. its a victa 160cc 2stroke engine, its from australia. this engine was modified to run a tillotson carb. i didnt mod it though i got it from school this engine was on a gokart. it was pretty good but at the time i didnt know anything about carbs or performance so it never ran at its best. if it was tuned properly and had a tuned pipe it would have been really fast. if you want a similar engine lawn boy still makes 2 stroke lawn mowers, its very similar to that.
also some of my first few minibikes were 3d and out of square tubing. but i found that its very hard to make the frame straight with so many pieces. personally i cant have a crooked frame so i started to make flat frames because i can just lay it out on a table and it will be straight.
