I have been reading a ton of posts on here about the 03 starter gear upgrade, but have one question. I read an article that referred to an upgrade performed by the dealer, but it didn't detail what was done. They said you would know the upgrade was done on the bike because the dealer would put a punch mark above the VIN. My bike has this punch mark, but the starter gear cover is the 03 one(flat with chamfer edge). Does anyone know what this upgrade was? Is it sufficient, or do I need to do the full upgrade to the 04 gear? Thanks. BTW, I took my first ride on this bike today and really liked it. The suspension needs some tuning, but the motor puled really strong.
