My friend mentioned this movie to me, and I've searched far and wide to no avail!
Either his imagination has ran far too wild, or this movie is super obscure.

Made in the 80s or around that era, possibly 70s/90s, low budget more than likely, not popular. This kid/guy wants to impress this girl who only hangs out with the biker kids, and the biker kids are the popular kids. So anyways he builds this motorcycle from scrapyard parts basically and he dons an outfit that hides his identity and she swoons over him.

HEEEELP!
