My chain bent in the crank case. I am looking for something really good, preferably 'prestretched' Pirate and every one else seems to be out.
I don't know if it's a 415, it's whatever came with my Grubee GT5.
Also I am looking for simple performance upgrades that either bolt on or are easy to install (not tearing into the motor) I already have a new pipe and an NT carb and an NGK.
Edit: looking for more torque. Also do centrifugal clutch kits fit on a GT5? heard 9/10 parts don't fit out of the box on a Grubee.
