Honda DJ-1 showcase + exhaust

My DJ-1 recently had engine surgery and now has a 72cc big bore. This engine uses: -Malossi bore -Malossi head -Naraku big valve dio intake -Polini CP19 carburetor -Polini Variator -Malossi belt -Malossi clutch -Malossi gears -Malossi clutch bell -Chameleon Paralyzer-III exhaust The block remains a stock AF05E with no porting or trenching. The bike itself is a Honda Elite 50 that has been converted to a DJ-1 using all original Honda parts. I do not own the rights to the song played in the video.
