there's a stigma about the '03's that's been around for a while due to the original Gates belt and then there are those that dismiss the '03 model and talk smack of them. those ass clowns give the year model a bad name. there's nothing wrong interchangeability of the parts between the '03's and newer, the exceptions are the belt, front and rear sprockets and side stand switch. everything else is plug and play...I'm wondering if it was just a interchangeable part or was wrong entirely that's holding up potential sales.
