It was a night and day difference after I installed this on my 1994 Z50R kart track race bike. For a 88cc bike this thing screams! Only issue I had is I didn't like the VM26 carb. I ended up buying the 20mm carb kit Fast50's sells, and it fixed any of the issues I was having with bogging. This is a tremendous power upgrades! Revs to the moon and back!
