Can you guys give me some advice? I don't want to gear down as i drive this bike on the street and it's slow enough there as it is (top speed i mean) I would already gear taller but I know it would hurt my trail driving. Can I get a heavier flywheel? I know it's already heavier then a YZ, but is there a heavier one from yamaha or aftermarket? Is there any other ideas you guys can give me.
